Updating foreign key values

Question

I have a database application in which a group is modeled like this:

TABLE Group
(
  group_id integer primary key,
  group_owner_id integer
)

TABLE GroupItem
(
         


        

Answer 1

Does SQL Server not support UPDATE CASCADE? :-

Foreign Key (group_id, group_owner_id)
 references Group(group_id, group_owner_id)
 ON UPDATE CASCADE

Then you simply update the Group table's group_owner_id.
