BUG: ANSI Full Outer Join and Non-ANSI Join May Cause Handled AV

Article ID: 169346

Article Last Modified on 10/3/2003



APPLIES TO

  • Microsoft SQL Server 6.5 Standard Edition



This article was previously published under Q169346

BUG #: 16833 (6.5)

SYMPTOMS

Optimizing a query may cause a handled access violation (AV) that stops the clients thread on the server if all of the following conditions are true:

  • The query contains the same table more than once.
  • The query does an ANSI Full Outer Join with one of the instances of the duplicated table.
  • The second instance of the table is joined to another table without the ANSI Join syntax.
  • There is no join condition between the instances of the table.


WORKAROUND

To work around this problem, rewrite the query:

  • Create a join condition between the two or more instances of the table.
  • Remove one of the instances of the table from the query.
  • Change the ANSI join to either a Left or Right Outer Join.


STATUS

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