ok, so more odd-ball questions
I have two columns in a table:
bool_bill | billing_id
one is a boolean that determines if we bill a customer, and the other one
is NULL if we don't, and has a billing_id of that customer if we do. the
billing_id uses a foreign key on the billing table to check that the
billing_id exists.
what I'd like to do is if bool_bill = y, then there has to be something in
billing_id (automatically checked with the foreign key).
again, do I need a function for this?
thanks!!!
