         my $drh = $proto->SUPER::driver($attr);
         ...
         return $drh->{class};
         }
 
     package DBD::myDriver::dr;
 
     @ISA = qw(DBI::DBD::SqlEngine::dr);
 
     sub data_sources { ... }

     package DBD::myDriver::Statement;
 
     @ISA = qw(DBI::DBD::SqlEngine::Statement);
 
     sub open_table { ... }

DESCRIPTION

DBI::DBD::SqlEngine abstracts the usage of SQL engines from the DBD. DBD authors can concentrate on the data retrieval they want to provide.

It is strongly recommended that you read DBD::File::Developers and DBD::File::Roadmap, because many of the DBD::File API is provided by DBI::DBD::SqlEngine.

Currently the API of DBI::DBD::SqlEngine is experimental and will likely change in the near future to provide the table meta data basics like DBD::File.

Where can I go for more help?

For questions about installation or usage, please ask on the dbi-dev@perl.org mailing list.

If you have a bug report, patch or suggestion, please open a new report ticket on CPAN, if there is not already one for the issue you want to report. Of course, you can mail any of the module maintainers, but it is less likely to be missed if it is reported on RT.

Report tickets should contain a detailed description of the bug or enhancement request you want to report and at least an easy way to verify/reproduce the issue and any supplied fix. Patches are always welcome, too.
