BUG #: 15572 (6.0), 15405 (6.5)



SYMPTOMS
The TRUNCATE statement fails with the following error message:

Msg 4712, Level 16, State 1

Cannot truncate table ' ' because it is being referenced by a

foreign key constraint.

Deleting from the table produces the following error:

Msg 439, Level 16, State 1

Unable to find foreign key constraints for table ' ' in dbid

'x' though table is flagged as having them.



WORKAROUND
To work around this problem, do the following:


 * 1) Back up the database.
 * 2) Drop and re-create the table.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server versions 6.0 and 6.5. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.



MORE INFORMATION
This problem occurs if the table once had a constraint defined, but the constraint was later removed by the ALTER statement.
