That does not make any sense in OO or RDBMS terms. Your database will not allow you to have a FK to two different tables. In OO, you would not want a relationship to two different classes not in an inheritance hierarchy. At the very least your code would be littered with casts and instanceof tests. Ugly.
As a interesting point of fact, I have a customer with a legacy database that does exactly this, so it is possible. Just because it is ugly (and yes, it is) and doesn't make any sense, doesn't mean that a customer won't do it.
But please, don't! Paul _______________________________________________ Do not post admin requests to the list. They will be ignored.
