hi,
i am confused between these keys. say i create two tables. Now, i
would like to know - which table i need to create primery key and in
which table foreign key, how do i relate them when i write a query.
While creating foreign key do we have to mention that this key has
primery key in some perticular table.
i have not understood the concept. pl explain
