BUG#: 11796 (6.00)



SYMPTOMS
The IF UPDATE clause will return FALSE in a UPDATE trigger if the is referenced by a foreign key constraint. The IF UPDATE clause will return TRUE in an INSERT trigger or if the foreign key constraint on the referencing table is removed.



WORKAROUND
Remove the foreign key from the referencing table.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server 6.0 and 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



MORE INFORMATION
Note that the update trigger will only get fired in this type of situation if the update does not violate the foreign key constraint. By design, SQL Server prevents a trigger from executing if a constraint is violated.
