cascade="all_delete_orphan" -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Niclas Pehrsson Sent: den 14 maj 2009 11:08 To: nhusers Subject: [nhusers] Parent Child problem Hi I earlier posted this post: http://groups.google.com/group/nhusers/browse_thread/thread/b06317e4d6b8a1e0# The post was about a parent child scenario where I didn't want the child to know about its parent. The problem were that I got 2 calls to the DB for each child row, one Insert, and then one Update. I solved this by adding a many-to-one reference in the child mapping with not-null=true and inverse=true on the parent. Now Im facing the problem that when I delete a child from my parent it will not being deleted, so how can I solve this? I want to be able to save my parent, with its childs with only inserts no updates. I want to be able to delete one child from my parent by calling remove on the childs list and then when I make Save on the parent the childs will be removed. Can I make it happen? Or should I just ignore the updates for each child? Im not only thinking performance in the two sql queries being executed for each child, im thinking that it would be harder to make something going wrong in the database if I keep the columns where I allow null's at a low level. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
