Good news for the upcoming 1.5.4 release of jOOQ (scheduled for the end of February)! I have implemented code generation and query execution support for the Apache Derby RDMBS. This means we're on track with the roadmap of RDMBS that should be supported by jOOQ. If you have any more input / requests, feel free to answer to this post or add an answer to stack overflow (MS SQL and Sybase are priorities): http://stackoverflow.com/questions/4685107/what-other-rdbms-should-my-open-source-java-persistence-library-support
Then again, feel free to provide an implementation for your RDMBS of choice :-) See the contribution guidelines here: https://sourceforge.net/apps/trac/jooq/wiki/Contribute I will put more effort into the stability of this new integration, as I am facing similar issues with Derby as we faced before with DB2. Derby expects NULL values to be typed in various occasions where jOOQ cannot provide a type. This means that some integration tests currently fail: https://sourceforge.net/apps/trac/jooq/ticket/240 Another issue with Derby may be related to an actual bug in the Derby RDMBS itself: https://sourceforge.net/apps/trac/jooq/ticket/238 Cheers Lukas
