Question

Is there a way to find out which record caused such a violation in Hibernate?

Normally you add objects to session and at the end you persist them. If such an error occurs it takes a while to track down which record has violated the constraint.

Is there way to find out which record caused (either to “toString() in case of new objects or Primary Key in case of existing objects should simplify debug process enormously.

Thanks.

Answer 1

I simply set a breakpoint in AbstractEntityPersister::performInsert(...) to find out the offending record.

As _NT said may be MySQL supports this but not Oracle.

But will keep this open to know any elegant solution.
