NAME
       DBI::DBD::SqlEngine - Base class for DBI drivers without their own SQL engine

SYNOPSIS
           package DBD::myDriver;

           use base qw(DBI::DBD::SqlEngine);

           sub driver
           {
               ...
               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::db;

           @ISA = qw(DBI::DBD::SqlEngine::db);

           sub init_valid_attributes { ... }
           sub init_default_attributes { ... }
           sub set_versions { ... }
           sub validate_STORE_attr { my ($dbh, $attrib, $value) = @_; ... }
           sub validate_FETCH_attr { my ($dbh, $attrib) = @_; ... }
           sub get_myd_versions { ... }
           sub get_avail_tables { ... }

           package DBD::myDriver::st;

           @ISA = qw(DBI::DBD::SqlEngine::st);

           sub FETCH { ... }
           sub STORE { ... }

           package DBD::myDriver::Statement;

           @ISA = qw(DBI::DBD::SqlEngine::Statement);

           sub open_table { ... }

           package DBD::myDriver::Table;

           @ISA = qw(DBI::DBD::SqlEngine::Table);

           sub new { ... }

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-devATperl.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.
