[hibernate-dev] Statements issued for unidirectional one-to-many with @JoinColumn

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
