This is a real newbie question. I am the proud owner of "Hibernate in Action" but I haven't encountered the solution to this (not to say its not there just that I haven't seen it yet).

I have two tables PARENT and CHILD



What is the correct way to map this? The CHILD rows are dependant on their PARENT row. The conceptual issue for me is I have to have an <id> tag in the child.hbm.xml but it isn't generated from a sequence, hilo or anything else; it comes from the parent. If I had to guess I would say that I should use the "assigned" value for the generator...

I am using Hibernate 2.1 against Oracle 8i.

Thanks for any suggestions

Guess you're looking for a 1:1 mapping where both sides do have the same primary key. If yes, read all of chapter 5.1.11 of the reference manual.

Thanks Ernst, I'll do that.
