I am trying to create two tables: parent and child. Child inherits from the parent and has a foregn key (FK) referencing parent's primary key (PK). Suppose parent table has one row with PK = 1 and I have one row in the child table with FK=1 and PK=2. Now, I want to insert another row in the child table with FK = 2, however it won't let me do this, since parent table does not have a record with PK = 2.
I was expecting that children tables will also be searched when verifying a foreign key constraint referencing the parent table.
Is there a way to force this kind of "hierarchical" foreign key constraint check?
Thanks.
Oleg
