+=head1 NAME
+
+DBIx::Class::Storage::DBI::Sybase - Sybase support for DBIx::Class
+
+=head1 SYNOPSIS
+
+This subclass supports L<DBD::Sybase> for real Sybase databases. If you are
+using an MSSQL database via L<DBD::Sybase>, your storage will be reblessed to
+L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>.
+
+=head1 DESCRIPTION
+
+If your version of Sybase does not support placeholders, then your storage
+will be reblessed to L<DBIx::Class::Storage::DBI::Sybase::NoBindVars>. You can
+also enable that driver explicitly, see the documentation for more details.
+
+With this driver there is unfortunately no way to get the C<last_insert_id>
+without doing a C<SELECT MAX(col)>.
+
+But your queries will be cached.
+
+A recommended L<DBIx::Class::Storage::DBI/connect_info> setting:
+
+ on_connect_call => [['datetime_setup'], ['blob_setup', log_on_update => 0]]

-=head1 NAME
+=head1 FreeTDS
-DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
+This driver supports L<DBD::Sybase> compiled against FreeTDS
+(L<http://www.freetds.org/>) to the best of our ability, however it is
+recommended that you recompile L<DBD::Sybase> against the Sybase Open Client
+libraries. They are a part of the Sybase ASE distribution:
-=head1 SYNOPSIS
+The Open Client FAQ is here:
+L<http://www.isug.com/Sybase_FAQ/ASE/section7.html>.
-This subclass supports L<DBD::Sybase> for real Sybase databases. If
-you are using an MSSQL database via L<DBD::Sybase>, see
-L<DBIx::Class::Storage::DBI::Sybase::MSSQL>.
+Sybase ASE for Linux (which comes with the Open Client libraries) may be
+downloaded here: L<http://response.sybase.com/forms/ASE_Linux_Download>.
-=head1 CAVEATS
+To see if you're using FreeTDS check C<< $schema->storage->using_freetds >>, or run:
-This storage driver uses L<DBIx::Class::Storage::DBI::NoBindVars> as a base.
-This means that bind variables will be interpolated (properly quoted of course)
-into the SQL query itself, without using bind placeholders.
+ perl -MDBI -le 'my $dbh = DBI->connect($dsn, $user, $pass); print $dbh->{syb_oc_version}'
-More importantly this means that caching of prepared statements is explicitly
-disabled, as the interpolation renders it useless.
+Some versions of the libraries involved will not support placeholders, in which
+case the storage will be reblessed to
+L<DBIx::Class::Storage::DBI::Sybase::NoBindVars>.
-=head1 AUTHORS
+In some configurations, placeholders will work but will throw implicit
+conversion errors for anything that's not expecting a string. In such a case,
+the C<auto_cast> option is automatically set, which you may enable yourself with
+L</connect_call_set_auto_cast> (see the description of that method for more
+details.)
+
+In other configurations, placeholers will work just as they do with the Sybase
+Open Client libraries.
+
+Inserts or updates of TEXT/IMAGE columns will B<NOT> work with FreeTDS.
+
+=head1 MAXIMUM CONNECTIONS
+
+The TDS protocol makes separate connections to the server for active statements
+in the background. By default the number of such connections is limited to 25,
+on both the client side and the server side.
+
+This is a bit too low for a complex L<DBIx::Class> application, so on connection
+the client side setting is set to C<256> (see L<DBD::Sybase/maxConnect>.) You
+can override it to whatever setting you like in the DSN.
+
+See
+L<http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.ase_15.0.sag1/html/sag1/sag1272.htm>
+for information on changing the setting on the server side.
+
+=head1 DATES
-Brandon L Black <blblack@gmail.com>
+See L</connect_call_datetime_setup> to setup date formats
+for L<DBIx::Class::InflateColumn::DateTime>.
+
+=head1 TEXT/IMAGE COLUMNS
+
+L<DBD::Sybase> compiled with FreeTDS will B<NOT> allow you to insert or update
+C<TEXT/IMAGE> columns.
+
+Setting C<< $dbh->{LongReadLen} >> will also not work with FreeTDS use either:
+
+ $schema->storage->dbh->do("SET TEXTSIZE $bytes");
+
+or
+
+ $schema->storage->set_textsize($bytes);
+
+instead.
+
+However, the C<LongReadLen> you pass in
+L<DBIx::Class::Storage::DBI/connect_info> is used to execute the equivalent
+C<SET TEXTSIZE> command on connection.
+
+See L</connect_call_blob_setup> for a L<DBIx::Class::Storage::DBI/connect_info>
+setting you need to work with C<IMAGE> columns.

+=head1 NAME
+
+DBIx::Class::Storage::DBI::Sybase::NoBindVars - Storage::DBI subclass for Sybase
+without placeholder support
+
+=head1 DESCRIPTION
+
+If you're using this driver than your version of Sybase, or the libraries you
+use to connect to it, do not support placeholders.
+
+You can also enable this driver explicitly using:
+
+ my $schema = SchemaClass->clone;
+ $schema->storage_type('::DBI::Sybase::NoBindVars');
+ $schema->connect($dsn, $user, $pass, \%opts);
+
+See the discussion in L<< DBD::Sybase/Using ? Placeholders & bind parameters to
+$sth->execute >> for details on the pros and cons of using placeholders.
+
+One advantage of not using placeholders is that C<select @@identity> will work
+for obtainging the last insert id of an C<IDENTITY> column, instead of having to
+do C<select max(col)> in a transaction as the base Sybase driver does.
+
+When using this driver, bind variables will be interpolated (properly quoted of
+course) into the SQL query itself, without using placeholders.
+
+The caching of prepared statements is also explicitly disabled, as the
+interpolation renders it useless.
