Hi there.
I am working with a database that has no primary keys. This schema is beyond my control. As recommended I have configured the mappings to have logical keys, despite no keys existing.
Where a table contains data that would break the key constraint (if it had one), the call to session.delete fails with the message "SQL insert, update or delete failed (row not found)". Logging would indicate that Hibernate has deleted multiple records when it expected to delete only one. The attempt to delete the second record with the same primary key results in the exception.
I attempted to work around this by using a raw SQL query, but I received an exception along the lines of "cursor state invalid".
Any advice on how to get around this problem?
Regards
Jem
