DESCRIPTIONDBI::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.
