BUG: Stored Proc Can Cause Thread-Level AV After Dump/Load

• Microsoft SQL Server, version 6.0

SYMPTOMS

If a stored procedure creates a temporary table and executes another stored procedure that creates a temporary table with the same table name, it can cause a thread-level access violation (AV) the first time this stored procedure is executed after the database is dumped and then restored from the dump.

CAUSE

Limited testing has shown that the scenario for reproducing this problem has a narrow scope:

1. The first stored procedure must create a local temporary table.

   must create a local temporary table with the same table name as the
   temporary table created in the first stored procedure.

   Loading the database right after dump, and executing the first stored
   procedure will demonstrate the problem. Subsequent execution of these
   stored procedures will work fine.

WORKAROUND

Do not create a temporary table with the same table name within two stored procedures if one stored procedure needs to call the other one.

STATUS

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