Hi,
I must be missing something simple. When I try to set the foreign key constraint, it fails. Here is the description:
1. I added new table PART_CLASS with primary column CLASS_PK (Int), Identity.
2. I added to PARTS table a column CLASS_PK (int), default 0
I want to be sure that when/if the row/record in PART_CLASS is deleted, all referenced rows in PARTS set the value in columnd CLASS_PK to default (0).
I think the constraint, when I set it up in SSMS, fails because table PARTS has many records and all of them have value 0 in the column CLASS_PK. But table PART_CLASS has no records. So SQL Server does not find a record in PART_CLASS of CLASS_PK value 0.
How do you deal with this? TIA.
