Tom,

        I would disagree in some circumstances. But one does need to minimize = them at all cost. I prefer a before insert/update trigger that does the = same thing, but that too can become a problem.

Peter,

I totally agree with you. Allowing Fk references from outside of the = schema
is inviting confusion, duplication and disaster. There is really no = good
reason for it.

Whoa there everybody!

While the answer is quite correct, of course (I read the FM years ago), = what
has not been raised is the danger of allowing reference to multiply unhindered across numerous schemas.

Be very careful if you choose to do this, otherwise, without a little = care,
you may manage to lock your entire database solid with conflicting FKs!

We did, learned our lesson, and now reference is ONLY permitted within = the
one corporate schema.
