Hi,
I have been testing the following scenario:
Parent table has PK Integer. This key cannot have NULL; this is an Identity column.
Child table has FK with the constraint set to the PK of the parent. If I set a value of this FK of one of the rows to NULL, I get no error. I thought that because the constraint requires that FK has to have a value in the parent table and the parent table has no NULL values, I should get an error. But I don't. What am I missing? TIA.
