Revision history for DBIx::Class
+ - Complete Sybase RDBMS support including:
+ - Support for TEXT/IMAGE columns
+ - Support for the 'money' datatype
+ - Transaction savepoints support
- - Support for bind variables when connecting via Sybase OpenClient
++ - Support for bind variables when connecting to a newer Sybase with
++ OpenClient libraries
++ - Support for bind variables over FreeTDS with CASTs when needed
+ - Support for interpolated variables with proper quoting when
- connecting via FreeTDS
++ connecting to an older Sybase or via FreeTDS
+ - Fixed a complex prefetch + regular join regression introduced
+ in 0.08108
+ - SQLT related fixes:
+ - sqlt_type is now called on the correct storage object
+ - hooks can now see the correct producer_type
+ - POD improvements

+ This API is B<EXPERIMENTAL>, will almost definitely change in the future, and
+ currently only used by L<::AutoCast|DBIx::Class::Storage::DBI::AutoCast> and
+ L<::Sybase|DBIx::Class::Storage::DBI::Sybase>.
+
+ The default implementation returns C<undef>, implement in your Storage driver if
+ you need this functionality.
- sub sqlt_type { shift->_get_dbh->{Driver}->{Name} }
+ Should map types from other databases to the native RDBMS type, for example
+ C<VARCHAR2> to C<VARCHAR>.
+ Types with modifiers should map to the underlying data type. For example,
+ C<INTEGER AUTO_INCREMENT> should become C<INTEGER>.
+
+ Composite types should map to the container type, for example
+ C<ENUM(foo,bar,baz)> becomes C<ENUM>.
