BUG# NT: 16544 (6.50)



SYMPTOMS
If a SELECT query is optimized using the optimizer hint "INDEX =", a CURSOR declared using the same SELECT and having the same optimizer hint may not optimize identically. Both performance and showplan demonstrate that the HINT index is being used in the first case, but not in the second.



WORKAROUND
To work around this problem, move relevant data into a separate table that has the desired indexing structure, and apply the cursor to it.



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.
