Steve, all,
I have a model with two entities, Parent and Child, and an
unidirectional one-to-many association from the former to the latter.
Via @JoinColumn on the association it is ensured that the Parent FK is
stored in the Child table, i.e. without a separate join table. When
inserting a Parent and several Child entities, I see the following
statements:
INSERT INTO parent (id, name) VALUES (?,?)
INSERT INTO child (id, childname) VALUES (?,?)
INSERT INTO child (id, childname) values (?,?)
UPDATE CHILD SET Parent_id=? WHERE id=?
UPDATE CHILD SET Parent_id=? WHERE id=?
Why is it that the FK is propagated through separate updates instead
of doing it as part of the Child insert?
Thanks,
--Gunnar
