Morten,
I'd like to help you with actual code, but I can't, because the version of
MySQL I use doesn't implement foreign key constraints.
In my own code (written in the C API), I plan on checking these constraints
myself. But I can't implement them in the tables themselves.
Best,
Steve Fromm

Hello MySQL programmers,
suppose we have an Enhanced ER diagram,
with entities as classes/ subclasses connected through
some IS-A relationship.
How can this be Coded in MySQL Please?
