Unanswered: supertype relationships
Is there a way to create a supertype/subtype table in sql server 2000 or is supertype/subtype an abstract idea rather than an option on creating a table?
i would like to set up a supertype table:
and two subtype tables:
how do i set this up so that I cant have the same personid in employee and customer. How do i make sure that the personid is in either one or the other.
With foreign keys and 2 triggers...
But what do you mean that it has to be 1 or the other...it could be none...
