SYMPTOMS
The join order is not controllable in UPDATE statements, even though SET FORCEPLAN is ON. The optimizer does not permit the override on the join sequence.



WORKAROUND
Proper index design and query design aids the optimizer in choosing the desired join sequence. Updating statistics on the tables involved in the join also results in the proper join order for performance considerations.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server versions 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.
