The "Migrating databases to IBM Cloudscape Version 10.0" at IBM lists changes between Cloudscape 5.1 and Derby: http://www.ibm.com/software/data/cloudscape/pubs/cloudscape10-migrate.html To answer your direct question, Java data types and static method calls to dbclasses drops out. I think this is what you're talking about, but I'm new myself and have little experience with the earlier CS releases. Nobody should hesitate to dive in and correct/clarify anything I say. Derby now supports SQL functions and stored procedures implemented in Java. The To Do list at http://incubator.apache.org/derby/DerbyToDo.html has helpful mail list pointers to feature topics, including one on supporting user defined types. I hope this helps. regards -jean
