Dino, Not trying to be a "database purist" here, but...
If table A has no key, then why X,Y, and Z belong in one table? And, table B has no key, then why P,Q, and R belong in one table? And even more so, why are you trying to put X,Y,Z,P,Q,R into one table? May be, if you tell us, what business entity/rule you are trying to implement here, it'll be easier to help you.
