RE: Force unique constraint to be enforced at statement execution?
Not exactly familiar with Spring Data JPA but I am with JPA with container managed transactions. Assuming you have a handle on the EntityManager, invoke the 'flush' method on it which will cause the entity manager to perform the database operations before the commit. You can then wrap your code with a try/catch block if needed to catch the exception that occurs. -Original Message- From: Matthew Adams [mailto:matt...@matthewadams.me] Sent: Tuesday, January 08, 2013 1:46 PM To: derby-user@db.apache.org Subject: Force unique constraint to be enforced at statement execution? Hi all, How do I force a unique constraint to be enforced upon statement execution instead of at transaction commit? I'm using Spring Data JPA over DataNucleus & Derby (embedded), and Spring's persistence exception translation proxy is not translating the unique constraint exception because it's happening at transaction commit instead of when the statement is executed.

Hi Matthew, I am not familiar with how your application stack defers constraint enforcement until commit time. Derby constraints are always enforced at statement end and never deferred to commit time. There is an outstanding enhancement request for deferring enforcement: https://issues.apache.org/jira/browse/DERBY-532. If you run in autocommit mode, statement and transaction boundaries coincide. More information on Derby constraints can be found in the section titled "CONSTRAINT clause" in the Derby Reference Manual.
