A database-abstraction package?

[Thomas Weholt]

Hi,

I need to make my project work with SQLite, MySQL and Postgresql, but I
don't want to create and maintain a set of table-schemas for all of them.
I'd rather specify this information in a common format and then let some
piece of code generate and run the sql-statements to create the tables in
the database. When I insert, update or delete records I also want a common
interface. In my project I use alot of auto-increment primary keys so this
would have to be handled as well.

Does anybody know if there are any such module or package available already?
If not I've got to start working on one and it would be nice to have some
pointers or guidelines if somebody has any ideas or opionions. A system
capable of handling any database would be best, but as a minimum I need to
support SQLite and MySQL, on Linux and Windows.
