Revision history for DBIx::Class
+0.08109 2009-08-18 08:35:00 (UTC)
+ - Replication updates:
+ - Improved the replication tests so that they are more reliable
+ and accurate, and hopefully solve some cross platform issues.
+ - Bugfixes related to naming particular replicants in a
+ 'force_pool' attribute.
+ - Lots of documentation updates, including a new Introduction.pod
+ file.
+ - Fixed the way we detect transaction to make this more reliable
+ and forward looking.
+ - Fixed some trouble with the way Moose Types are used.
+ - Made discard_chages/get_from_storage replication aware (they
+ now read from the master storage by default)
+ - Refactor of MSSQL storage drivers, with some new features:
+ - Support for placeholders for MSSQL via DBD::Sybase with proper
+ autodetection
+ - 'uniqueidentifier' support with auto newid()
+ - Dynamic cursor support and other MARS options for ODBC
+ - savepoints with auto_savepoint => 1
+ - Support for MSSQL 'money' type
+ - Support for 'smalldatetime' type used in MSSQL and Sybase for
+ InflateColumn::DateTime
+ - support for Postgres 'timestamp without timezone' type in
+ InflateColumn::DateTime (RT#48389)
+ - Added new MySQL specific on_connect_call macro 'set_strict_mode'
+ (also known as make_mysql_not_suck_as_much)
+ - Multiple prefetch-related fixes:
+ - Adjust overly agressive subquery join-chain pruning
+ - Always preserve the outer join-chain - fixes numerous
+ problems with search_related chaining
+ - Deal with the distinct => 1 attribute properly when using
+ prefetch
+ - An extension of the select-hashref syntax, allowing labeling
+ SQL-side aliasing: select => [ { max => 'foo', -as => 'bar' } ]
+ - Massive optimization of the DBI storage layer - reduce the
+ amount of connected() ping-calls
+ - Some fixes of multi-create corner cases
+ - Multiple POD improvements
+ - Added exception when resultset is called without an argument
+ - Improved support for non-schema-qualified tables under
+ Postgres (fixed last_insert_id sequence name auto-detection)
+
+0.08108 2009-07-05 23:15:00 (UTC)
+ - Fixed the has_many prefetch with limit/group deficiency -
+ it is now possible to select "top 5 commenters" while
+ prefetching all their comments
+ - New resultsed method count_rs, returns a ::ResultSetColumn
+ which in turn returns a single count value
+ - Even better support of count with limit
+ - New on_connect_call/on_disconnect_call functionality (check
+ POD of Storage::DBI)
+ - Automatic datetime handling environment/session setup for
+ Oracle via connect_call_datetime_setup()
+ - count/all on related left-joined empty resultsets now correctly
+ returns 0/()
+ - Fixed regression when both page and offset are specified on
+ a resultset
+ - Fixed HRI returning too many empty results on multilevel
+ nonexisting prefetch
+ - make_column_dirty() now overwrites the deflated value with an
+ inflated one if such exists
+ - Fixed set_$rel with where restriction deleting rows outside
+ the restriction
+ - populate() returns the created objects or an arrayref of the
+ created objects depending on scalar vs. list context
+ - Fixed find_related on 'single' relationships - the former
+ implementation would overspecify the WHERE condition, reporting
+ no related objects when there in fact is one
+ - SQL::Translator::Parser::DBIx::Class now attaches tables to the
+ central schema object in relationship dependency order
+ - Fixed regression in set_column() preventing sourceless object
+ manipulations
+ - Fixed a bug in search_related doubling a join if the original
+ $rs already joins/prefetches the same relation
+ - Storage::DBI::connected() improvements for Oracle and Sybase
+ - Fixed prefetch+incomplete select regression introduced in
+ 0.08100
+ - MSSQL limit (TOP emulation) fixes and improvements
+
+0.08107 2009-06-14 08:21:00 (UTC)
+ - Fix serialization regression introduced in 0.08103 (affects
+ Cursor::Cached)
+ - POD fixes
+ - Fixed incomplete ::Replicated debug output
+
+0.08106 2009-06-11 21:42:00 (UTC)

+ (proper timezone handling)
+ - Fix more test problems
+
+0.08105 2009-06-11 19:04:00 (UTC)
+ - Update of numeric columns now properly uses != to determine
+ dirtyness instead of the usual eq
+ - Fixes to IC::DT tests
+ - Fixed exception when undef_if_invalid and timezone are both set
+ on an invalid datetime column
+
+0.08104 2009-06-10 13:38:00 (UTC)
+ - order_by now can take \[$sql, @bind] as in
+ order_by => { -desc => \['colA LIKE ?', 'somestring'] }
+ - SQL::Abstract errors are now properly croak()ed with the
+ correct trace
+ - populate() now properly reports the dataset slice in case of
+ an exception
+ - Fixed corner case when populate() erroneously falls back to
+ create()
+ - Work around braindead mysql when doing subquery counts on
+ resultsets containing identically named columns from several
+ tables
+ - Fixed m2m add_to_$rel to invoke find_or_create on the far
+ side of the relation, to avoid duplicates
+ - DBIC now properly handles empty inserts (invoking all default
+ values from the DB, normally via INSERT INTO tbl DEFAULT VALUES
+ - Fix find_or_new/create to stop returning random rows when
+ default value insert is requested (RT#28875)
+ - Make IC::DT extra warning state the column name too
+ - It is now possible to transparrently search() on columns
+ requiring DBI bind (i.e. PostgreSQL BLOB)
+ - as_query is now a Storage::DBI method, so custom cursors can
+ be seamlessly used
+ - Fix search_related regression introduced in 0.08103
+
+0.08103 2009-05-26 19:50:00 (UTC)
+ - Multiple $resultset -> count/update/delete fixes. Now any
+ of these operations will succeed, regardless of the complexity
+ of $resultset. distinct, group_by, join, prefetch are all
+ supported with expected results
+ - Return value of $rs->delete is now the storage return value
+ and not 1 as it used to be
+ - don't pass SQL functions into GROUP BY
+ - Remove MultiDistinctEmulation.pm, effectively deprecating
+ { select => { distinct => [ qw/col1 col2/ ] } }
+ - Change ->count code to work correctly with DISTINCT (distinct => 1)
+ via GROUP BY
+ - Removed interpolation of bind vars for as_query - placeholders
+ are preserved and nested query bind variables are properly
+ merged in the correct order
+ - Refactor DBIx::Class::Storage::DBI::Sybase to automatically
+ load a subclass, namely Microsoft_SQL_Server.pm
+ (similar to DBIx::Class::Storage::DBI::ODBC)
+ - Refactor InflateColumn::DateTime to allow components to
+ circumvent DateTime parsing
+ - Support inflation of timestamp datatype
+ - Support BLOB and CLOB datatypes on Oracle
+ - Storage::DBI::Replicated::Balancer::Random:
+ added master_read_weight
+ - Storage::DBI::Replicated: storage opts from connect_info,
+ connect_info merging to replicants, hashref connect_info support,
+ improved trace output, other bug fixes/cleanups
+ - distinct => 1 with prefetch now groups by all columns
+ - on_connect_do accepts a single string equivalent to a one
+ element arrayref (RT#45159)
+ - DB2 limit + offset now works correctly
+ - Sybase now supports autoinc PKs (RT#40265)
+ - Prefetch on joins over duplicate relations now works
+ correctly (RT#28451)
+ - "timestamp with time zone" columns (for Pg) now get inflated with a
+ time zone information preserved
+ - MSSQL Top limit-emulation improvements (GROUP BY and subquery support)
+ - ResultSetColumn will not lose the joins infered from a parent
+ resultset prefetch
+
+0.08102 2009-04-30 08:29:00 (UTC)
+ - Fixed two subtle bugs when using columns or select/as
+ paired with a join (limited prefetch)
+ - Fixed breakage of cdbi tests (RT#45551)
+ - Some POD improvements
+
+0.08101 2009-04-27 09:45:00 (UTC)
+ - Fix +select, +as, +columns and include_columns being stripped
+ by $rs->get_column
+ - move load_optional_class from DBIx::Class::Componentised to

+0.08099_08 2009-03-30 00:00:00 (UTC)
+ - Fixed taint mode with load_namespaces
+ - Putting IC::DateTime locale, timezone or floating_tz_ok attributes into
+ extra => {} has been deprecated. The new way is to put these things
+ directly into the columns definition

+ - Document db-side default_value caveats
+ - Search_like() now warns to indicate deprecation in 0.09.

+ was NULL and the row was not stored would unexpectedly fail
- Split sql statements for deploy only if SQLT::Producer returned a scalar
containing all statements to be executed
- Add as_query() for ResultSet and ResultSetColumn. This makes subqueries
- possible. See the Cookbook for details. (robkinyon, michaelr)
+ possible. See the Cookbook for details.
- Massive rewrite of Ordered to properly handle position constraints and
to make it more matpath-friendly
- deploy_statements called ddl_filename with the $version and $dir arguments
- in the wrong order. (groditi)
+ in the wrong order.
- columns/+columns attributes now support { as => select } hahsrefs
- support for views both in DBIC and via deploy() in SQLT

additional argument format type
- InflateColumn::DateTime: add warning about floating timezone
- InflateColumn::DateTime: possible to enforce/skip inflation
- - delete throws exception if passed arguments to prevent drunken mishaps. (purge)

- Fix storage to copy scalar conds before regexping to avoid
trying to modify a constant in odd edge cases
- Related resultsets on uninserted objects are now empty
- "belongs_to" to "contains/refers/something"
Using inflated objects/references as values in searches
- - Goes together with subselects above
- should deflate then run search
-FilterColumn - like Inflate, only for changing scalar values
- - This seems to be vaporware atm..
-
SQL/API feature complete?
- UNION
- proper join conditions!
Moosification - ouch
+Metamodel stuff - introspection
+
Prefetch improvements
- slow on mysql, speedup?
- multi has_many prefetch
- - paging working with prefetch
Magically "discover" needed joins/prefetches and add them
- eg $books->search({ 'author.name' => 'Fred'}), autoadds: join => 'author'
- also guess aliases when supplying column names that are on joined/related tables
-Metamodel stuff - introspection
-
Storage API/restructure
- call update/insert etc on the ResultSource, which then calls to storage
- handle different storages/db-specific code better
Documentation - improvements
- better indexing for finding of stuff in general
- more cross-referencing of docs

- ResultSource objects caching ->resultset causes interesting problems
- find why XSUB dumper kills schema in Catalyst (may be Pg only?)

- find a way to un-wantarray search without breaking compat
- - audit logging component
- delay relationship setup if done via ->load_classes
- double-sided relationships
- make short form of class specifier in relationships work
We should still support the old inflate/deflate syntax, but this new
way should be recommended.
-2006-02-07 by castaway
- - Extract DBIC::SQL::Abstract into a separate module for CPAN

- Leftovers for next dev-release
- Rewrite the test suite to rely on $schema->deploy, allowing for seamless
testing of various RDBMS using the same tests
- - Proper support of default create (i.e. create({}) ), with proper workarounds
- for different Storage's
- Automatically infer quote_char/name_sep from $schema->storage
- - Finally incorporate View support (needs real tests)
- Fix and properly test chained search attribute merging
-
-2008-11-07 by ribasushi
- - Be loud when a relationship resolution fails because we did not select/as
- a neccessary pk
- Recursive update() (all code seems to be already available)
- - $rs->populate changes its syntax depending on wantarray context (BAD)
- Also the interface differs from $schema->populate (not so good)

__PACKAGE__->add_columns(
starts_when => { data_type => 'datetime' }
+ create_date => { data_type => 'date' }
);
NOTE: You B<must> load C<InflateColumn::DateTime> B<before> C<Core>. See
If you want to set a specific timezone and locale for that field, use:
__PACKAGE__->add_columns(
- starts_when => { data_type => 'datetime', extra => { timezone => "America/Chicago", locale => "de_DE" } }
+ starts_when => { data_type => 'datetime', timezone => "America/Chicago", locale => "de_DE" }
);
If you want to inflate no matter what data_type your column is,
__PACKAGE__->add_columns(
starts_when => { data_type => 'varchar', inflate_datetime => 1 }
);
-
+
__PACKAGE__->add_columns(
starts_when => { data_type => 'varchar', inflate_date => 1 }
);
It's also possible to explicitly skip inflation:
-
+
__PACKAGE__->add_columns(
starts_when => { data_type => 'datetime', inflate_datetime => 0 }
);
+NOTE: Don't rely on C<InflateColumn::DateTime> to parse date strings for you.
+The column is set directly for any non-references and C<InflateColumn::DateTime>
+is completely bypassed. Instead, use an input parser to create a DateTime
+object. For instance, if your user input comes as a 'YYYY-MM-DD' string, you can
+use C<DateTime::Format::ISO8601> thusly:
+
+ use DateTime::Format::ISO8601;
+ my $dt = DateTime::Format::ISO8601->parse_datetime('YYYY-MM-DD');
+
=head1 DESCRIPTION
This module figures out the type of DateTime::Format::* class to
that this feature is new as of 0.07, so it may not be perfect yet - bug
reports to the list very much welcome).
+If the data_type of a field is C<date>, C<datetime> or C<timestamp> (or
+a derivative of these datatypes, e.g. C<timestamp with timezone>, this
+module will automatically call the appropriate parse/format method for
+deflation/inflation as defined in the storage class. For instance, for
+a C<datetime> field the methods C<parse_datetime> and C<format_datetime>
+would be called on deflation/inflation. If the storage class does not
+provide a specialized inflator/deflator, C<[parse|format]_datetime> will
+be used as a fallback. See L<DateTime::Format> for more information on
+date formatting.
+
For more help with using components, see L<DBIx::Class::Manual::Component/USING>.
=cut
In the case of an invalid date, L<DateTime> will throw an exception. To
bypass these exceptions and just have the inflation return undef, use
the C<datetime_undef_if_invalid> option in the column info:

=head1 USAGE NOTES
-If you have a datetime column with the C<timezone> extra setting, and subsenquently
+If you have a datetime column with an associated C<timezone>, and subsequently
create/update this column with a DateTime object in the L<DateTime::TimeZone::Floating>
timezone, you will get a warning (as there is a very good chance this will not have the
result you expect). For example:
__PACKAGE__->add_columns(
- starts_when => { data_type => 'datetime', extra => { timezone => "America/Chicago" } }
+ starts_when => { data_type => 'datetime', timezone => "America/Chicago" }
);
my $event = $schema->resultset('EventTZ')->create({
=item Suppress the check on per-column basis
__PACKAGE__->add_columns(
- starts_when => { data_type => 'datetime', extra => { timezone => "America/Chicago", floating_tz_ok => 1 } }
+ starts_when => { data_type => 'datetime', timezone => "America/Chicago", floating_tz_ok => 1 }
);
=item Suppress the check globally
=back
-
+Putting extra attributes like timezone, locale or floating_tz_ok into extra => {} has been
+B<DEPRECATED> because this gets you into trouble using L<DBIx::Class::Schema::Versioned>.
+Instead put it directly into the columns definition like in the examples above. If you still
+use the old way you'll see a warning - please fix your code then!

=item *

While single() takes a search condition just like search() does, it does
_not_ accept search attributes. However one can always chain a single() to
a search():
- my $top_cd = $cd_rs -> search({}, { order_by => 'rating' }) -> single;
+ my $top_cd = $cd_rs->search({}, { order_by => 'rating' })->single;
=item *
+
Since single() is the engine behind find(), it is designed to fetch a
single row per database query. Thus a warning will be issued when the
underlying SELECT returns more than one row. Sometimes however this usage
at the top of the charts at any given time. If you know what you are doing,
you can silence the warning by explicitly limiting the resultset size:
- my $top_cd = $cd_rs -> search ({}, { order_by => 'rating', rows => 1 }) -> single;
+ my $top_cd = $cd_rs->search ({}, { order_by => 'rating', rows => 1 })->single;

Sometimes you have to run arbitrary SQL because your query is too complex
(e.g. it contains Unions, Sub-Selects, Stored Procedures, etc.) or has to
-be optimized for your database in a special way, but you still want to
-get the results as a L<DBIx::Class::ResultSet>.
-The recommended way to accomplish this is by defining a separate ResultSource
-for your query. You can then inject complete SQL statements using a scalar
-reference (this is a feature of L<SQL::Abstract>).
+be optimized for your database in a special way, but you still want to
+get the results as a L<DBIx::Class::ResultSet>.
-Say you want to run a complex custom query on your user data, here's what
-you have to add to your User class:
+This is accomplished by defining a
+L<ResultSource::View|DBIx::Class::ResultSource::View> for your query,
+almost like you would define a regular ResultSource.
- package My::Schema::User;
-
+ package My::Schema::Result::UserFriendsComplex;
+ use strict;
+ use warnings;
use base qw/DBIx::Class/;
-
- # ->load_components, ->table, ->add_columns, etc.
-
- # Make a new ResultSource based on the User class
- my $source = __PACKAGE__->result_source_instance();
- my $new_source = $source->new( $source );
- $new_source->source_name( 'UserFriendsComplex' );
-
- # Hand in your query as a scalar reference
- # It will be added as a sub-select after FROM,
- # so pay attention to the surrounding brackets!
- $new_source->name( \<<SQL );
- ( SELECT u.* FROM user u
- INNER JOIN user_friends f ON u.id = f.user_id
- WHERE f.friend_user_id = ?
- UNION
- SELECT u.* FROM user u
- INNER JOIN user_friends f ON u.id = f.friend_user_id
- WHERE f.user_id = ? )
- SQL
-
- # Finally, register your new ResultSource with your Schema
- My::Schema->register_extra_source( 'UserFriendsComplex' => $new_source );
+
+ __PACKAGE__->load_components('Core');
+ __PACKAGE__->table_class('DBIx::Class::ResultSource::View');
+
+ # ->table, ->add_columns, etc.
+
+ # do not attempt to deploy() this view
+ __PACKAGE__->result_source_instance->is_virtual(1);
+
+ __PACKAGE__->result_source_instance->view_definition(q[
+ SELECT u.* FROM user u
+ INNER JOIN user_friends f ON u.id = f.user_id
+ WHERE f.friend_user_id = ?
+ UNION
+ SELECT u.* FROM user u
+ INNER JOIN user_friends f ON u.id = f.friend_user_id
+ WHERE f.user_id = ?
+ ]);
Next, you can execute your complex query using bind parameters like this:
- my $friends = [ $schema->resultset( 'UserFriendsComplex' )->search( {},
+ my $friends = $schema->resultset( 'UserFriendsComplex' )->search( {},
{
bind => [ 12345, 12345 ]
}
- ) ];
-
+ );
+
... and you'll get back a perfect L<DBIx::Class::ResultSet> (except, of course,
that you cannot modify the rows it contains, ie. cannot call L</update>,
L</delete>, ... on it).
-If you prefer to have the definitions of these custom ResultSources in separate
-files (instead of stuffing all of them into the same resultset class), you can
-achieve the same with subclassing the resultset class and defining the
-ResultSource there:
+Note that you cannot have bind parameters unless is_virtual is set to true.

+results by, one or more columns in a related table.
+
+This requires that you have defined the L<DBIx::Class::Relationship>. For example :
+
+ My::Schema::CD->has_many( artists => 'My::Schema::Artist', 'artist_id');
+
+To return all CDs matching a particular artist name, you specify the name of the relationship ('artists'):
my $rs = $schema->resultset('CD')->search(
{
- 'artist.name' => 'Bob Marley'
+ 'artists.name' => 'Bob Marley'
},
{
- join => 'artist', # join the artist table
+ join => 'artists', # join the artist table
}
);
# JOIN artist ON cd.artist = artist.id
# WHERE artist.name = 'Bob Marley'
+In that example both the join, and the condition use the relationship name rather than the table name
+(see L<DBIx::Class::Manual::Joining> for more details on aliasing ).
+
If required, you can now sort on any column in the related tables by including
-it in your C<order_by> attribute:

},
{
- join => 'artist',
- order_by => [qw/ artist.name /]
+ join => 'artists',
+ order_by => [qw/ artists.name /]
}
);
my $rs = $schema->resultset('CD')->search(
{
- 'artist.name' => 'Bob Marley'
+ 'artists.name' => 'Bob Marley'
},
{
- join => 'artist',
- order_by => [qw/ artist.name /],
- prefetch => 'artist' # return artist data too!
+ join => 'artists',
+ order_by => [qw/ artists.name /],
+ prefetch => 'artists' # return artist data too!
}
);
so no additional SQL statements are executed. You now have a much more
efficient query.
-Note that as of L<DBIx::Class> 0.05999_01, C<prefetch> I<can> be used with
-C<has_many> relationships.
-
Also note that C<prefetch> should only be used when you know you will
definitely use data from a related table. Pre-fetching related tables when you
only need columns from the main table will make performance worse!

- my $artist_rs = $schema->resultset('Artist');
+ my $artist_rs = $schema->resultset('Artist');
This can be useful when you don't want to pass around a Schema object to every
method.

+=head2 Dynamic Sub-classing DBIx::Class proxy classes
AKA multi-class object inflation from one table
-
+
L<DBIx::Class> classes are proxy classes, therefore some different
techniques need to be employed for more than basic subclassing. In
this example we have a single user table that carries a boolean bit
for admin. We would like like to give the admin users
-objects(L<DBIx::Class::Row>) the same methods as a regular user but
+objects (L<DBIx::Class::Row>) the same methods as a regular user but
also special admin only methods. It doesn't make sense to create two
seperate proxy-class files for this. We would be copying all the user
methods into the Admin class. There is a cleaner way to accomplish
grab the object being returned, inspect the values we are looking for,
bless it if it's an admin object, and then return it. See the example
below:

+=head2 Relationships across DB schemas
+
+Mapping relationships across L<DB schemas|DBIx::Class::Manual::Glossary/DB schema>
+is easy as long as the schemas themselves are all accessible via the same DBI
+connection. In most cases, this means that they are on the same database host
+as each other and your connecting database user has the proper permissions to them.
+
+To accomplish this one only needs to specify the DB schema name in the table
+declaration, like so...
+
+ package MyDatabase::Main::Artist;
+ use base qw/DBIx::Class/;
+ __PACKAGE__->load_components(qw/PK::Auto Core/);
+
+ __PACKAGE__->table('database1.artist'); # will use "database1.artist" in FROM clause
+
+ __PACKAGE__->add_columns(qw/ artist_id name /);
+ __PACKAGE__->set_primary_key('artist_id');
+ __PACKAGE__->has_many('cds' => 'MyDatabase::Main::Cd');
+
+ 1;
+
+Whatever string you specify there will be used to build the "FROM" clause in SQL
+queries.
+
+The big drawback to this is you now have DB schema names hardcoded in your
+class files. This becomes especially troublesome if you have multiple instances
+of your application to support a change lifecycle (e.g. DEV, TEST, PROD) and
+the DB schemas are named based on the environment (e.g. database1_dev).
+
+However, one can dynamically "map" to the proper DB schema by overriding the
+L<connection|DBIx::Class::Schama/connection> method in your Schema class and
+building a renaming facility, like so:
+
+ package MyDatabase::Schema;
+ use Moose;
+
+ extends 'DBIx::Class::Schema';
+
+ around connection => sub {
+ my ( $inner, $self, $dsn, $username, $pass, $attr ) = ( shift, @_ );
+
+ my $postfix = delete $attr->{schema_name_postfix};
+
+ $inner->(@_);
+
+ if ( $postfix ) {
+ $self->append_db_name($postfix);
+ }
+ };
+
+ sub append_db_name {
+ my ( $self, $postfix ) = @_;
+
+ my @sources_with_db
+ = grep
+ { $_->name =~ /^\w+\./mx }
+ map
+ { $self->source($_) }
+ $self->sources;
+
+ foreach my $source (@sources_with_db) {
+ my $name = $source->name;
+ $name =~ s{^(\w+)\.}{${1}${postfix}\.}mx;
+
+ $source->name($name);
+ }
+ }
+
+ 1;
+
+By overridding the L<connection|DBIx::Class::Schama/connection>
+method and extracting a custom option from the provided \%attr hashref one can
+then simply iterate over all the Schema's ResultSources, renaming them as
+needed.
+
+To use this facility, simply add or modify the \%attr hashref that is passed to
+L<connection|DBIx::Class::Schama/connect>, as follows:
+
+ my $schema
+ = MyDatabase::Schema->connect(
+ $dsn,
+ $user,
+ $pass,
+ {
+ schema_name_postfix => '_dev'
+ # ... Other options as desired ...
+ })
+
+Obviously, one could accomplish even more advanced mapping via a hash map or a
+callback routine.

package MyAppDB::Dual;
use strict;
use warnings;
"dummy",
{ data_type => "VARCHAR2", is_nullable => 0, size => 1 },

-
+
my $rs = $schema->resultset('Dual')->search(undef,
{ select => [ 'sydate' ],
as => [ 'now' ]
},
);
-
+
All you have to do now is be careful how you access your resultset, the below
will not work because there is no column called 'now' in the Dual table class
-
+
while (my $dual = $rs->next) {
print $dual->now."\n";
}
# Can't locate object method "now" via package "MyAppDB::Dual" at headshot.pl line 23.
-

You could of course use 'dummy' in C<as> instead of 'now', or C<add_columns> to
your Dual class for whatever you wanted to select from dual, but that's just
silly, instead use C<get_column>
-
+
while (my $dual = $rs->next) {
print $dual->get_column('now')."\n";
}
-
+
Or use C<cursor>
-
+
my $cursor = $rs->cursor;
while (my @vals = $cursor->next) {

}
-
+
+In case you're going to use this "trick" together with L<DBIx::Class::Schema/deploy> or
+L<DBIx::Class::Schema/create_ddl_dir> a table called "dual" will be created in your
+current schema. This would overlap "sys.dual" and you could not fetch "sysdate" or
+"sequence.nextval" anymore from dual. To avoid this problem, just tell
+L<SQL::Translator> to not create table dual:
+
+ my $sqlt_args = {
+ add_drop_table => 1,
+ parser_args => { sources => [ grep $_ ne 'Dual', schema->sources ] },
+ };
+ $schema->create_ddl_dir( [qw/Oracle/], undef, './sql', undef, $sqlt_args );
+

-
+
$rs->result_class('DBIx::Class::ResultClass::HashRefInflator');

+
+=head2 Cached statements
+
+L<DBIx::Class> normally caches all statements with L<< prepare_cached()|DBI/prepare_cached >>.
+This is normally a good idea, but if too many statements are cached, the database may use too much
+memory and may eventually run out and fail entirely. If you suspect this may be the case, you may want
+to examine DBI's L<< CachedKids|DBI/CachedKidsCachedKids_(hash_ref) >> hash:
+
+ # print all currently cached prepared statements
+ print for keys %{$schema->storage->dbh->{CachedKids}};
+ # get a count of currently cached prepared statements
+ my $count = scalar keys %{$schema->storage->dbh->{CachedKids}};
+
+If it's appropriate, you can simply clear these statements, automatically deallocating them in the
+database:
+
+ my $kids = $schema->storage->dbh->{CachedKids};
+ delete @{$kids}{keys %$kids} if scalar keys %$kids > 100;
+
+But what you probably want is to expire unused statements and not those that are used frequently.
+You can accomplish this with L<Tie::Cache> or L<Tie::Cache::LRU>:
+
+ use Tie::Cache;
+ use DB::Main;

Once you've defined the basic classes, either manually or using
$album->set_column('title', 'Presence');
$title = $album->get_column('title');

+Just like with L<Class::DBI>, you call C<update> to save your changes to the

in the new record:

So, joins are a way of extending simple select statements to include
fields from other, related, tables. There are various types of joins,
depending on which combination of the data you wish to retrieve, see

=item *
-Each method starts with a "head2" statement of it's name.
+Each method starts with a "head2" statement of its name.
+
+Just the plain method name, not an example of how to call it, or a link.
+This is to ensure easy linking to method documentation from other POD.
=item *
-The header is followed by a one-item list.
+The header is followed by a two-item list. This contains a description
+of the arguments the method is expected to take, and an indication of
+what the method returns.
-The single item provides a list of all possible values for the
+The first item provides a list of all possible values for the
arguments of the method in order, separated by C<, >, preceeded by the
text "Arguments: "
=item *
+%var - A hashref variable (list of key/value pairs) - rarely used in DBIx::Class.
+
+Reading an argument as a hash variable will consume all subsequent
+method arguments, use with caution.
+
+=item *
+
+@var - An array variable (list of values).
+
+Reading an argument as a array variable will consume all subsequent
+method arguments, use with caution.
+
+=item *
+
? - Optional, should be placed after the argument type and name.
+ ## Correct
+ \%myhashref|\@myarrayref?
+
+ ## Wrong
+ \%myhashref?|\@myarrayref
+
+Applies to the entire argument.
+
+Optional arguments can be left out of method calls, unless the caller
+needs to pass in any of the following arguments. In which case the
+caller should pass C<undef> in place of the missing argument.
+
=item *
-| - Alternate argument types.
+| - Alternate argument content types.
+
+At least one of these must be supplied unless the argument is also
+marked optional.
=back
-NOTES:
+The second item starts with the text "Return value:". The remainder of
+the line is either the text "undefined", a text describing the result of
+the method, or a variable with a descriptive name.
-If several arguments are optional, it is always possible to pass
-C<undef> as one optional argument in order to skip it and provide a
-value for the following ones. This does not need to be indicated in
-the Arguments line, it is assumed.
+ ## Good examples
+ =item Return value: undefined
+ =item Return value: A schema object
+ =item Return value: $classname
-The C<?> for optional arguments always applies to the entire argument
-value, not a particular type or argument.
+ ## Bad examples
+ =item Return value: The names
+
+"undefined" means the method does not deliberately return a value, and
+the caller should not use or rely on anything it does return. (Perl
+functions always return something, usually the result of the last code
+statement, if there is no explicit return statement.)
=item *
The description paragraph is followed by another list. Each item in
the list explains one of the possible argument/type combinations.
+This list may be omitted if the author feels that the variable names are
+self-explanatory enough to not require it. Use best judgement.
+
=item *
The argument list is followed by some examples of how to use the
Alternatively use the C<< storage->debug >> class method:-
- $class->storage->debug(1);
+ $schema->storage->debug(1);
To send the output somewhere else set debugfh:-
- $class->storage->debugfh(IO::File->new('/tmp/trace.out', 'w');
+ $schema->storage->debugfh(IO::File->new('/tmp/trace.out', 'w');
Alternatively you can do this with the environment variable too:-
L<DBI> version 1.50 and L<DBD::Pg> 1.43 are known to work.

+
+When a resultset is chained from another resultset, conditions and

+
+L</join>, L</prefetch>, L</+select>, L</+as> attributes are merged
+into the existing ones from the original resultset.
+
+The L</where>, L</having> attribute, and any search conditions are
+merged with an SQL C<AND> to the existing condition from the original
+resultset.
+
+All other attributes are overridden by any new ones supplied in the
+search attributes.

CAVEAT: C<search_literal> is provided for Class::DBI compatibility and should

+It is equivalent to calling $schema->search(\[]), but if you want to ensure
+columns are bound correctly, use C<search>.
+
+Example of how to use C<search> instead of C<search_literal>
+

require C<search_literal>.

=head1 DESCRIPTION
-A ResultSource is a component of a schema from which results can be directly
-retrieved, most usually a table (see L<DBIx::Class::ResultSource::Table>)
+A ResultSource is an object that represents a source of data for querying.
+
+This class is a base class for various specialised types of result
+sources, for example L<DBIx::Class::ResultSource::Table>. Table is the
+default result source type, so one is created for you when defining a
+result class as described in the synopsis above.
+
+More specifically, the L<DBIx::Class::Core> component pulls in the
+L<DBIx::Class::ResultSourceProxy::Table> as a base class, which
+defines the L<table|DBIx::Class::ResultSourceProxy::Table/table>
+method. When called, C<table> creates and stores an instance of
+L<DBIx::Class::ResultSoure::Table>. Luckily, to use tables as result
+sources, you don't need to remember any of this.
+
+Result sources representing select queries, or views, can also be
+created, see L<DBIx::Class::ResultSource::View> for full details.
+
+=head2 Finding result source objects
+
+As mentioned above, a result source instance is created and stored for
+you when you define a L<Result Class|DBIx::Class::Manual::Glossary/Result Class>.
+
+You can retrieve the result source at runtime in the following ways:
+
+=over
+
+=item From a Schema object:
+
+ $schema->source($source_name);
+
+=item From a Row object:
+
+ $row->result_source;
+
+=item From a ResultSet object:
-Basic view support also exists, see L<<DBIx::Class::ResultSource::View>.

=head1 METHODS
$source->add_columns('col1' => \%col1_info, 'col2' => \%col2_info, ...);
-Adds columns to the result source. If supplied key => hashref pairs, uses
-the hashref as the column_info for that column. Repeated calls of this
-method will add more columns, not replace them.
+Adds columns to the result source. If supplied colname => hashref
+pairs, uses the hashref as the L</column_info> for that column. Repeated
+calls of this method will add more columns, not replace them.
The column names given will be created as accessor methods on your
L<DBIx::Class::Row> objects. You can change the name of the accessor
=item accessor
+ { accessor => '_name' }
+
+ # example use, replace standard accessor with one of your own:

+ $self->_name($value);
+
+ return $self->_name();
+ }

the name of the column will be used.

-This contains the column type. It is automatically filled by the
-L<SQL::Translator::Producer::DBIx::Class::File> producer, and the

=item is_auto_increment

+
+ { is_numeric => 1 }
+
+Set this to a true or false value (not C<undef>) to explicitly specify

+decides whether to consider a column dirty after an update: if
+C<is_numeric> is true a numeric comparison C<< != >> will take place
+instead of the usual C<eq>
+
+If not specified the storage class will attempt to figure this out on
+first access to the column, based on the column C<data_type>. The
+result will be cached in this attribute.

View definition SQL is deployed to your database on

+=head1 EXAMPLES
+
+Having created the MyDB::Schema::Year2000CDs schema as shown in the SYNOPSIS

+
+ $2000_cds = $schema->resultset('Year2000CDs')
+ ->search()
+ ->all();
+ $count = $schema->resultset('Year2000CDs')
+ ->search()
+ ->count();
+
+If you modified the schema to include a placeholder
+
+ __PACKAGE__->result_source_instance->view_definition(
+ "SELECT cdid, artist, title FROM cd WHERE year ='?'"
+ );
+
+and ensuring you have is_virtual set to true:
+
+ __PACKAGE__->result_source_instance->is_virtual(1);
+
+You could now say:
+
+ $2001_cds = $schema->resultset('Year2000CDs')
+ ->search({}, { bind => [2001] })
+ ->all();
+ $count = $schema->resultset('Year2000CDs')

+Please note that if a value is not passed to new, no value will be sent
+in the SQL INSERT call, and the column will therefore assume whatever
+default value was specified in your database. While DBIC will retrieve the
+value of autoincrement columns, it will never make an explicit database
+trip to retrieve default values assigned by the RDBMS. You can explicitly
+request that all values be fetched back from the database by calling
+L</discard_changes>, or you can supply an explicit C<undef> to columns
+with NULL as the default, and save yourself a SELECT.
+
+ CAVEAT:
+
+ The behavior described above will backfire if you use a foreign key column
+ with a database-defined default. If you call the relationship accessor on
+ an object that doesn't have a set value for the FK column, DBIC will throw
+ an exception, as it has no way of knowing the PK of the related object (if
+ there is one).

+=head1 NAME
+
+DBIx::Class::SQLAHacks::OracleJoins - Pre-ANSI Joins-via-Where-Clause Syntax
+
+=head1 PURPOSE
+
+This module was originally written to support Oracle < 9i where ANSI joins
+weren't supported at all, but became the module for Oracle >= 8 because
+Oracle's optimising of ANSI joins is horrible. (See:
+http://scsys.co.uk:8001/7495)
+
+=head1 SYNOPSIS
+
+Not intended for use directly; used as the sql_maker_class for schemas and components.
+
+=head1 DESCRIPTION
+
+Implements pre-ANSI joins specified in the where clause. Instead of:
+
+ SELECT x FROM y JOIN z ON y.id = z.id
+
+It will write:
+
+ SELECT x FROM y, z WHERE y.id = z.id
+
+It should properly support left joins, and right joins. Full outer joins are
+not possible due to the fact that Oracle requires the entire query be written
+to union the results of a left and right join, and by the time this module is
+called to create the where query and table definition part of the sql query,
+it's already too late.
+
+=head1 METHODS
+
+=over
+
+=item select ($\@$;$$@)
+
+Replaces DBIx::Class::SQLAHacks's select() method, which calls _oracle_joins()
+to modify the column and table list before calling SUPER::select().
+
+=item _recurse_from ($$\@)
+
+Recursive subroutine that builds the table list.
+
+=item _oracle_joins ($$$@)
+
+Creates the left/right relationship in the where query.
+
+=back
+
+=head1 BUGS
+
+Does not support full outer joins.
+Probably lots more.

Since wantarray context is basically the same as looping over $rs->create(...)
you won't see any performance benefits and in this case the method is more for
convenience. Void context sends the column information directly to storage
data in-place on the Schema class. You should probably be calling
L</connect> to get a proper Schema object instead.

-If a exception occurs, the transaction will be rolled back. This is still very
-experiemental, and we are not 100% sure it is working right when nested. The
-onus is on you as the user to make sure you dont forget to call
-$C<$txn->commit>.
+If an exception occurs, or the guard object otherwise leaves the scope
+before C<< $txn_guard->commit >> is called, the transaction will be rolled
+back by an explicit L</txn_rollback> call. In essence this is akin to
+using a L</txn_begin>/L</txn_commit> pair, without having to worry
+about calling L</txn_rollback> at the right places. Note that since there
+is no defined code closure, there will be no retries and other magic upon
+database disconnection. If you need such functionality see L</txn_do>.

DBIx::Class can do some wonderful magic with handling exceptions,
disconnections, and transactions when you use C<< AutoCommit => 1 >>
-combined with C<txn_do> for transaction support.
+(the default) combined with C<txn_do> for transaction support.
If you set C<< AutoCommit => 0 >> in your connect info, then you are always
in an assumed transaction between commits, and you're telling us you'd
be with raw DBI.

+DBIx::Class::Storage::DBI::AmbiguousGlob - Storage component for RDBMS supporting multicolumn in clauses
+
+=head1 DESCRIPTION
+
+Some servers choke on things like:
+
+ COUNT(*) FROM (SELECT tab1.col, tab2.col FROM tab1 JOIN tab2 ... )
+
+claiming that col is a duplicate column (it loses the table specifiers by
+the time it gets to the *). Thus for any subquery count we select only the
+primary keys of the main table in the inner query. This hopefully still
+hits the indexes and keeps the server happy.
+
+At this point the only overriden method is C<_subq_count_select()>

=head1 NAME
-DBIx::Class::Storage::DBI::MSSQL - Storage::DBI subclass for MSSQL
+DBIx::Class::Storage::DBI::MSSQL - Base Class for Microsoft SQL Server support
+in DBIx::Class
=head1 SYNOPSIS
-This subclass supports MSSQL, and can in theory be used directly
-via the C<storage_type> mechanism:
+This is the base class for Microsoft SQL Server support, used by
+L<DBIx::Class::Storage::DBI::ODBC::Microsoft_SQL_Server> and
+L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>.
+
+=head1 IMPLEMENTATION NOTES
+
+Microsoft SQL Server supports three methods of retrieving the IDENTITY
+value for inserted row: IDENT_CURRENT, @@IDENTITY, and SCOPE_IDENTITY().
+SCOPE_IDENTITY is used here because it is the safest. However, it must
+be called is the same execute statement, not just the same connection.
+
+So, this implementation appends a SELECT SCOPE_IDENTITY() statement
+onto each INSERT to accommodate that requirement.
+
+C<SELECT @@IDENTITY> can also be used by issuing:
+
+ $self->_identity_method('@@identity');
- $schema->storage_type('::DBI::MSSQL');
- $schema->connect_info('dbi:....', ...);
+it will only be used if SCOPE_IDENTITY() fails.
-However, as there is no L<DBD::MSSQL>, you will probably want to use
-one of the other DBD-specific MSSQL classes, such as
-L<DBIx::Class::Storage::DBI::Sybase::MSSQL>. These classes will
-merge this class with a DBD-specific class to obtain fully
-correct behavior for your scenario.
+This is more dangerous, as inserting into a table with an on insert trigger that
+inserts into another table with an identity will give erroneous results on
+recent versions of SQL Server.

+DBIx::Class::Storage::DBI::MultiColumnIn - Storage component for RDBMS supporting multicolumn in clauses

+
+While ANSI SQL does not define a multicolumn in operator, many databases can
+in fact understand WHERE (cola, colb) IN ( SELECT subcol_a, subcol_b ... )
+The storage class for any such RDBMS should inherit from this class, in order
+to dramatically speed up update/delete operations on joined multipk resultsets.
+
+At this point the only overriden method is C<_multipk_update_delete()>

-\r

-\r
-This module is currently considered alpha software and can change without notice.\r
-\r
-=head1 DESCRIPTION\r
-\r
-This class implements support specific to Microsoft Access over ODBC.\r
-\r
-It is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it\r
-detects a MS Access back-end.\r
-\r
-=head1 SUPPORTED VERSIONS\r
-\r
-This module have currently only been tested on MS Access 2003 using the Jet 4.0 engine.\r
-\r
-As far as my knowledge it should work on MS Access 2000 or later, but that have not been tested.\r
-Information about support for different version of MS Access is welcome.\r
-\r
-=head1 IMPLEMENTATION NOTES\r
-\r
-MS Access supports the @@IDENTITY function for retriving the id of the latest inserted row.\r
-@@IDENTITY is global to the connection, so to support the possibility of getting the last inserted\r
-id for different tables, the insert() function stores the inserted id on a per table basis.\r
-last_insert_id() then just returns the stored value.\r
-\r
-=head1 KNOWN ACCESS PROBLEMS\r
-\r

-\r
-=item Invalid precision value\r
-\r
-This error message is received when trying to store more than 255 characters in a MEMO field.\r
-The problem is (to my knowledge) an error in the MS Access ODBC driver. The problem is fixed\r
-by setting the C<data_type> of the column to C<SQL_LONGVARCHAR> in C<add_columns>. \r
-C<SQL_LONGVARCHAR> is a constant in the C<DBI> module.\r

+=head1 NAME
+
+DBIx::Class::Storage::DBI::ODBC::ACCESS - Support specific to MS Access over ODBC
+
+=head1 WARNING
+
+I am not a DBI, DBIx::Class or MS Access guru. Use this module with that in
+mind.
+
+This module is currently considered alpha software and can change without notice.
+
+=head1 DESCRIPTION
+
+This class implements support specific to Microsoft Access over ODBC.
+
+It is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it
+detects a MS Access back-end.
+
+=head1 SUPPORTED VERSIONS
+
+This module have currently only been tested on MS Access 2003 using the Jet 4.0 engine.
+
+As far as my knowledge it should work on MS Access 2000 or later, but that have not been tested.
+Information about support for different version of MS Access is welcome.
+
+=head1 IMPLEMENTATION NOTES
+
+MS Access supports the @@IDENTITY function for retriving the id of the latest inserted row.
+@@IDENTITY is global to the connection, so to support the possibility of getting the last inserted
+id for different tables, the insert() function stores the inserted id on a per table basis.
+last_insert_id() then just returns the stored value.
+
+=head1 KNOWN ACCESS PROBLEMS
+
+=over
+
+=item Invalid precision value
+
+This error message is received when trying to store more than 255 characters in a MEMO field.
+The problem is (to my knowledge) an error in the MS Access ODBC driver. The problem is fixed
+by setting the C<data_type> of the column to C<SQL_LONGVARCHAR> in C<add_columns>.
+C<SQL_LONGVARCHAR> is a constant in the C<DBI> module.

+=head1 IMPLEMENTED FUNCTIONS
+
+=head2 bind_attribute_by_data_type
+
+This function currently supports the SQL_LONGVARCHAR column type.

+This class implements support specific to Microsoft SQL Server over ODBC. It is
+loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it detects a
+MSSQL back-end.
+
+Most of the functionality is provided from the superclass
+L<DBIx::Class::Storage::DBI::MSSQL>.
+
+=head1 MULTIPLE ACTIVE STATEMENTS
+
+The following options are alternative ways to enable concurrent executing
+statement support. Each has its own advantages and drawbacks.
+
+=head2 connect_call_use_dynamic_cursors
+
+Use as:
-sub last_insert_id { shift->{_scope_identity} }
+ on_connect_call => 'use_dynamic_cursors'
-sub sqlt_type { 'SQLServer' }
+in your L<DBIx::Class::Storage::DBI/connect_info> as one way to enable multiple
+concurrent statements.
-sub _sql_maker_opts {
- my ( $self, $opts ) = @_;
+Will add C<< odbc_cursortype => 2 >> to your DBI connection attributes. See
+L<DBD::ODBC/odbc_cursortype> for more information.
- if ( $opts ) {
- $self->{_sql_maker_opts} = { %$opts };
- }
+Alternatively, you can add it yourself and dynamic cursor support will be
+automatically enabled.
- return { limit_dialect => 'Top', %{$self->{_sql_maker_opts}||{}} };
+If you're using FreeTDS, C<tds_version> must be set to at least C<8.0>.
+
+This will not work with CODE ref connect_info's.
+
+B<WARNING:> this will break C<SCOPE_IDENTITY()>, and C<SELECT @@IDENTITY> will
+be used instead, which on SQL Server 2005 and later will return erroneous
+results on tables which have an on insert trigger that inserts into another
+table with an C<IDENTITY> column.

-=head1 DESCRIPTION
+Use as:
-This class implements support specific to Microsoft SQL Server over ODBC,
-including auto-increment primary keys and SQL::Abstract::Limit dialect. It
-is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it
-detects a MSSQL back-end.
+ on_connect_call => 'use_server_cursors'
-=head1 IMPLEMENTATION NOTES
+May allow multiple active select statements. See
+L<DBD::ODBC/odbc_SQL_ROWSET_SIZE> for more information.
-Microsoft SQL Server supports three methods of retrieving the IDENTITY
-value for inserted row: IDENT_CURRENT, @@IDENTITY, and SCOPE_IDENTITY().
-SCOPE_IDENTITY is used here because it is the safest. However, it must
-be called is the same execute statement, not just the same connection.
+Takes an optional parameter for the value to set the attribute to, default is
+C<2>.
-So, this implementation appends a SELECT SCOPE_IDENTITY() statement
-onto each INSERT to accommodate that requirement.
+B<WARNING>: this does not work on all versions of SQL Server, and may lock up
+your database!

+bind_attribute_by_data_type.

This class implements autoincrements for PostgreSQL.
+=head1 POSTGRESQL SCHEMA SUPPORT
+
+This supports multiple PostgreSQL schemas, with one caveat: for
+performance reasons, the schema search path is queried the first time it is
+needed and CACHED for subsequent uses.
+
+For this reason, you should do any necessary manipulation of the
+PostgreSQL search path BEFORE instantiating your schema object, or as
+part of the on_connect_do option to connect(), for example:
+
+ my $schema = My::Schema->connect
+ ( $dsn,$user,$pass,
+ { on_connect_do =>
+ [ 'SET search_path TO myschema, foo, public' ],
+ },
+ );

+
+=head1 NAME
+
+DBIx::Class::Storage::DBI::Replicated::Introduction - Minimum Need to Know
+
+=head1 SYNOPSIS
+
+This is an introductory document for L<DBIx::Class::Storage::Replication>.
+
+This document is not an overview of what replication is or why you should be
+using it. It is not a document explaing how to setup MySQL native replication
+either. Copious external resources are avialable for both. This document
+presumes you have the basics down.
+
+=head1 DESCRIPTION
+
+L<DBIx::Class> supports a framework for using database replication. This system
+is integrated completely, which means once it's setup you should be able to
+automatically just start using a replication cluster without additional work or
+changes to your code. Some caveats apply, primarily related to the proper use
+of transactions (you are wrapping all your database modifying statements inside
+a transaction, right ;) ) however in our experience properly written DBIC will
+work transparently with Replicated storage.
+
+Currently we have support for MySQL native replication, which is relatively
+easy to install and configure. We also currently support single master to one
+or more replicants (also called 'slaves' in some documentation). However the
+framework is not specifically tied to the MySQL framework and supporting other
+replication systems or topographies should be possible. Please bring your
+patches and ideas to the #dbix-class IRC channel or the mailing list.
+
+For an easy way to start playing with MySQL native replication, see:
+L<MySQL::Sandbox>.
+
+If you are using this with a L<Catalyst> based appplication, you may also wish
+to see more recent updates to L<Catalyst::Model::DBIC::Schema>, which has
+support for replication configuration options as well.
+
+=head1 REPLICATED STORAGE
+
+By default, when you start L<DBIx::Class>, your Schema (L<DBIx::Class::Schema>)
+is assigned a storage_type, which when fully connected will reflect your
+underlying storage engine as defined by your choosen database driver. For
+example, if you connect to a MySQL database, your storage_type will be
+L<DBIx::Class::Storage::DBI::mysql> Your storage type class will contain
+database specific code to help smooth over the differences between databases
+and let L<DBIx::Class> do its thing.
+
+If you want to use replication, you will override this setting so that the
+replicated storage engine will 'wrap' your underlying storages and present to
+the end programmer a unified interface. This wrapper storage class will
+delegate method calls to either a master database or one or more replicated
+databases based on if they are read only (by default sent to the replicants)
+or write (reserved for the master). Additionally, the Replicated storage
+will monitor the health of your replicants and automatically drop them should
+one exceed configurable parameters. Later, it can automatically restore a
+replicant when its health is restored.
+
+This gives you a very robust system, since you can add or drop replicants
+and DBIC will automatically adjust itself accordingly.
+
+Additionally, if you need high data integrity, such as when you are executing
+a transaction, replicated storage will automatically delegate all database
+traffic to the master storage. There are several ways to enable this high
+integrity mode, but wrapping your statements inside a transaction is the easy
+and canonical option.
+
+=head1 PARTS OF REPLICATED STORAGE
+
+A replicated storage contains several parts. First, there is the replicated
+storage itself (L<DBIx::Class::Storage::DBI::Replicated>). A replicated storage
+takes a pool of replicants (L<DBIx::Class::Storage::DBI::Replicated::Pool>)
+and a software balancer (L<DBIx::Class::Storage::DBI::Replicated::Pool>). The
+balancer does the job of splitting up all the read traffic amongst each
+replicant in the Pool. Currently there are two types of balancers, a Random one
+which chooses a Replicant in the Pool using a naive randomizer algorithm, and a
+First replicant, which just uses the first one in the Pool (and obviously is
+only of value when you have a single replicant).
+
+=head1 REPLICATED STORAGE CONFIGURATION
+
+All the parts of replication can be altered dynamically at runtime, which makes
+it possibly to create a system that automatically scales under load by creating
+more replicants as needed, perhaps using a cloud system such as Amazon EC2.
+However, for common use you can setup your replicated storage to be enabled at
+the time you connect the databases. The following is a breakdown of how you
+may wish to do this. Again, if you are using L<Catalyst>, I strongly recommend
+you use (or upgrade to) the latest L<Catalyst::Model::DBIC::Schema>, which makes
+this job even easier.
+
+First, you need to connect your L<DBIx::Class::Schema>. Let's assume you have
+such a schema called, "MyApp::Schema".
+
+ use MyApp::Schema;
+ my $schema = MyApp::Schema->connect($dsn, $user, $pass);
+
+Next, you need to set the storage_type.
+
+ $schema->storage_type(
+ ::DBI::Replicated' => {
+ balancer_type => '::Random',
+ balancer_args => {
+ auto_validate_every => 5,
+ master_read_weight => 1
+ },
+ pool_args => {
+ maximum_lag =>2,
+ },
+ }
+ );
+
+Let's break down the settings. The method L<DBIx::Class::Schema/storage_type>
+takes one mandatory parameter, a scalar value, and an option second value which
+is a Hash Reference of configuration options for that storage. In this case,
+we are setting the Replicated storage type using '::DBI::Replicated' as the
+first value. You will only use a different value if you are subclassing the
+replicated storage, so for now just copy that first parameter.
+
+The second parameter contains a hash reference of stuff that gets passed to the
+replicated storage. L<DBIx::Class::Storage::DBI::Replicated/balancer_type> is
+the type of software load balancer you will use to split up traffic among all
+your replicants. Right now we have two options, "::Random" and "::First". You
+can review documentation for both at:
+
+L<DBIx::Class::Storage::DBI::Replicated::Balancer::First>,
+L<DBIx::Class::Storage::DBI::Replicated::Balancer::Random>.
+
+In this case we will have three replicants, so the ::Random option is the only
+one that makes sense.
+
+'balancer_args' get passed to the balancer when it's instantiated. All
+balancers have the 'auto_validate_every' option. This is the number of seconds
+we allow to pass between validation checks on a load balanced replicant. So
+the higher the number, the more possibility that your reads to the replicant
+may be inconsistant with what's on the master. Setting this number too low
+will result in increased database loads, so choose a number with care. Our
+experience is that setting the number around 5 seconds results in a good
+performance / integrity balance.
+
+'master_read_weight' is an option associated with the ::Random balancer. It
+allows you to let the master be read from. I usually leave this off (default
+is off).
+
+The 'pool_args' are configuration options associated with the replicant pool.
+This object (L<DBIx::Class::Storage::DBI::Replicated::Pool>) manages all the
+declared replicants. 'maximum_lag' is the number of seconds a replicant is
+allowed to lag behind the master before being temporarily removed from the pool.
+Keep in mind that the Balancer option 'auto_validate_every' determins how often
+a replicant is tested against this condition, so the true possible lag can be
+higher than the number you set. The default is zero.
+
+No matter how low you set the maximum_lag or the auto_validate_every settings,
+there is always the chance that your replicants will lag a bit behind the
+master for the supported replication system built into MySQL. You can ensure
+reliabily reads by using a transaction, which will force both read and write
+activity to the master, however this will increase the load on your master
+database.
+
+After you've configured the replicated storage, you need to add the connection
+information for the replicants:
+
+ $schema->storage->connect_replicants(
+ [$dsn1, $user, $pass, \%opts],
+ [$dsn2, $user, $pass, \%opts],
+ [$dsn3, $user, $pass, \%opts],
+ );
+
+These replicants should be configured as slaves to the master using the
+instructions for MySQL native replication, or if you are just learning, you
+will find L<MySQL::Sandbox> an easy way to set up a replication cluster.
+
+And now your $schema object is properly configured! Enjoy!

=head1 NAME
-DBIx::Class::Storage::DBI::mysql - Automatic primary key class for MySQL
+DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics
=head1 SYNOPSIS
- # In your table classes
- __PACKAGE__->load_components(qw/PK::Auto Core/);
- __PACKAGE__->set_primary_key('id');
+Storage::DBI autodetects the underlying MySQL database, and re-blesses the
+C<$storage> object into this class.
+
+ my $schema = MyDb::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } );
=head1 DESCRIPTION
-This class implements autoincrements for MySQL.
+This class implements MySQL specific bits of L<DBIx::Class::Storage::DBI>.
+
+It also provides a one-stop on-connect macro C<set_strict_mode> which sets
+session variables such that MySQL behaves more predictably as far as the
+SQL standard is concerned.

=head1 HOW TO USE
This is a test of the replicated storage system. This will work in one of
will try to test those. If you do that, it will assume the setup is properly
replicating. Your results may vary, but I have demonstrated this to work with
mysql native replication.

Exports functions that can be used to compare generated SQL and bind values.
-If L<SQL::Abstract::Test> (packaged in L<SQL::Abstract> versions 1.50 and
-above) is available, then it is used to perform the comparisons (all functions
-are delegated to id). Otherwise uses simple string comparison for the SQL
-statements and simple L<Data::Dumper>-like recursive stringification for
-comparison of bind values.
-
+This is a thin wrapper around L<SQL::Abstract::Test>, which makes it easier
+to compare as_query sql/bind arrayrefrefs directly.

+
+We have a number of reasons to believe that this is a development
+checkout and that you, the user, did not run `perl Makefile.PL`
+before using this code. You absolutely _must_ perform this step,
+as not doing so often results in a lot of wasted time for other
+contributors trying to assit you with "it broke!" problems.
+
+If you are seeing this message unexpectedly (i.e. you are in fact
+attempting a regular installation be it through CPAN or manually,
+set the variable DBICTEST_NO_MAKEFILE_VERIFICATION to a true value
+so you can continue. Also _make_absolutely_sure_ to report this to
+either the mailing list or to the irc channel as described in
+
+http://search.cpan.org/dist/DBIx-Class/lib/DBIx/Class.pm#GETTING_HELP/SUPPORT
+
+Failure to do this will make us believe that all these checks are
+indeed foolproof and we will remove the ability to override this
+entirely.

+things into the right spot is, likewise, pretty straightforward. Instead of
+storing things in a AoH, store them in a HoH keyed on the PKs of the the table,
+then convert to an AoH after all collapsing is done.
This implies that the collapse attribute can probably disappear or, at the
least, be turned into a boolean (which is how it's used in every other place).

-The fix is to, when using prefetch, take the query and put it into a subquery
-joined to the tables we're prefetching from. This might result in the same
-table being joined once in the main subquery and once in the main query. This
-may actually resolve other, unknown edgecase bugs. It is also the right way
-to do prefetching. Optimizations can come later.
-
-This means that:
- $foo_rs->search(
- { ... },
- {
- prefetch => 'bar',
- ...
- },
- );
-
-becomes:
- my $temp = $foo_rs->search(
- { ... },
- {
- join => 'bar',
- ...
- },
- );
- $foo_rs->storage->schema->resultset('foo')->search(
- undef,
- {
- from => [
- { me => $temp->as_query },
- ],
- prefetch => 'bar',
- },
- );
-
-Problem:
- * The prefetch->join change needs to happen ONLY IF there are conditions
- that depend on bar being joined.
- * How will this work when the $rs is further searched on? Those clauses
- need to be added to the subquery, not the outer one. This is particularly
- true if rows is added in the attribute later per the Pager.
