-=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)>. This is done safely in a transaction
-(locking the table.) See L</INSERTS WITH PLACEHOLDERS>.
-
-A recommended L<DBIx::Class::Storage::DBI/connect_info> setting:
-
-  on_connect_call => [['datetime_setup'], ['blob_setup', log_on_update => 0]]

-Also sets the C<log_on_update> value for blob write operations. The default is

-=head1 Schema::Loader Support
-
-There is an experimental branch of L<DBIx::Class::Schema::Loader> that will
-allow you to dump a schema from most (if not all) versions of Sybase.
-
-It is available via subversion from:
-
-  http://dev.catalyst.perl.org/repos/bast/branches/DBIx-Class-Schema-Loader/current/
-
-=head1 FreeTDS
-
-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:
-
-The Open Client FAQ is here:
-L<http://www.isug.com/Sybase_FAQ/ASE/section7.html>.
-
-Sybase ASE for Linux (which comes with the Open Client libraries) may be
-downloaded here: L<http://response.sybase.com/forms/ASE_Linux_Download>.
-
-To see if you're using FreeTDS check C<< $schema->storage->using_freetds >>, or run:
-
-  perl -MDBI -le 'my $dbh = DBI->connect($dsn, $user, $pass); print $dbh->{syb_oc_version}'
-
-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>.
-
-In some configurations, placeholders will work but will throw implicit type
-conversion errors for anything that's not expecting a string. In such a case,
-the C<auto_cast> option from L<DBIx::Class::Storage::DBI::AutoCast> is
-automatically set, which you may enable on connection with
-L<DBIx::Class::Storage::DBI::AutoCast/connect_call_set_auto_cast>. The type info
-for the C<CAST>s is taken from the L<DBIx::Class::ResultSource/data_type>
-definitions in your Result classes, and are mapped to a Sybase type (if it isn't
-already) using a mapping based on L<SQL::Translator>.
-
-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 INSERTS WITH PLACEHOLDERS
-
-With placeholders enabled, inserts are done in a transaction so that there are
-no concurrency issues with getting the inserted identity value using
-C<SELECT MAX(col)>, which is the only way to get the C<IDENTITY> value in this
-mode.
-
-When using C<DBIx::Class::Storage::DBI::Sybase::NoBindVars> transactions are
-disabled, as there are no concurrency issues with C<SELECT @@IDENTITY> as it's a
-session variable.

-=head1 TRANSACTIONS
-
-Due to limitations of the TDS protocol, L<DBD::Sybase>, or both; you cannot
-begin a transaction while there are active cursors. An active cursor is, for
-example, a L<ResultSet|DBIx::Class::ResultSet> that has been executed using
-C<next> or C<first> but has not been exhausted or
-L<reset|DBIx::Class::ResultSet/reset>.
-
-For example, this will not work:
-
-  $schema->txn_do(sub {
-    my $rs = $schema->resultset('Book');
-    while (my $row = $rs->next) {
-      $schema->resultset('MetaData')->create({
-        book_id => $row->id,
-        ...
-      });
-    }
-  });
-
-Transactions done for inserts in C<AutoCommit> mode when placeholders are in use
-are not affected, as they use an extra database handle to do the insert.
-
-Some workarounds:
-
-=over 4
-
-=item * use L<DBIx::Class::Storage::DBI::Replicated>
-
-=item * L<connect|DBIx::Class::Schema/connect> another L<Schema|DBIx::Class::Schema>
-
-=item * load the data from your cursor with L<DBIx::Class::ResultSet/all>

-=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
-
-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.
+=head1 NAME
 
-Setting C<< $dbh->{LongReadLen} >> will also not work with FreeTDS use either:
+DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
 
-  $schema->storage->dbh->do("SET TEXTSIZE $bytes");
+=head1 SYNOPSIS
 
-or
+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>.
 
-  $schema->storage->set_textsize($bytes);
+=head1 CAVEATS
 
-instead.
+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.
 
-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.
+More importantly this means that caching of prepared statements is explicitly
+disabled, as the interpolation renders it useless.
 
-See L</connect_call_blob_setup> for a L<DBIx::Class::Storage::DBI/connect_info>
-setting you need to work with C<IMAGE> columns.
