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.

- 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

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.
