Hi,

In one of my concurrent insert operation in the same table I'm getting the ConstraintViolationException.



Can Hibernate Optimistic Lock can help me in this regard?
As far I know that Optimistic locking work in update/delete operation on same record in the database.

Does it work for insert query as well?

I have created a version column in the target table (entity). But still getting the same exception(no optimisticLockException or StaleObjectStateException).

No, it doesn't work for inserts by principle:
optimistic Locking bases on comparing old version against new version.
To have an onld version you must have an already existing record.
