Hi

I have a simple question: what's the best way to delete a child record?

I'm doing it like this at the moment (pseudocode):

A contains B
therefore I have: a.getB();

How to delete:
B b = a.getB( )
a.setB(null)
save( a )
delete( b )

This gets around FK constraints. But, I would like to do this:



I've played around with the mapping and the 'cascade' option but haven't stumbled upon one that works for my case.



Thanks

you can use cascade = all-delete-orphan

Thanks, but that results in:

oh, yes i think thi is correct, bnecause tou association is one-to-one (by unique foreign key)association, so b is not dependent of a.

i think you can implement b as composite element of a.

Thanks, that gives me something to go on. I'll give it a whirl
