BUG: SELECT from View with UNION ALL and Aggregate Function AVs

• Microsoft SQL Server version 6.5

SYMPTOMS

You may receive a handled access violation (AV) if all of the following conditions are true:

• You issue a SELECT statement against a view.
  
  -and-



• That view uses UNION ALL to union a SELECT statement containing an aggregate function with another view.
  
  -and-



• That other view also contains UNION ALL.

WORKAROUND

To work around this problem, do any one of the following:

• Change any of the UNION ALL statements to a UNION.
  
  -or-



• Eliminate the aggregate function from the SELECT statement in the outer view.
  
  -or-



• Execute the Transact-SQL statements that make up the outer view directly (as opposed to selecting from the outer view).

STATUS

Microsoft has confirmed this to be a problem in SQL Server version 6.5.
