>>>In your signature, you have "If you can't win them, lose them." My slogan is somewhat more agressive, "If you can't join them, beat them." <vbg>

>>You surely meant two unjoinable tables in a SQL? So how do you beat them to have a foreign key into each other? Hold one hostage while the other goes across the border to smuggle a key? (we know domestic key won't work here)

>Yes, I mean one round table and one square table, they are very difficult to join. And I always use foreign keys, most of them are danish. Do you think I should try american keys and oval tables?

Try those little Swedish double-L-shaped keys by which you assemble every Ikea item of furniture :-)
