It would be nice if OpenJPA were a little smarter and only used CAST when necessary. Using the CAST causes any indexes not to be used so performance won't be what it should. > I saw some other DB2 functions that also are always CAST, so we may need to improve these also. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
