SYMPTOMS
A dynamic cursor retrieves the same row two times when all the following conditions are true:
- The dynamic cursor has an order-by clause that matches a non-clustered index.
- One or more key columns is updated to the same value that the column currently has. The key columns in the non-clustered index are used to specify order.
- One or more key columns can be assigned a null value,

WORKAROUND
To work around this problem, use one of the following methods:
Method 1
Switch to another cursor type instead of the dynamic-cursor type.
Method 2
Do not update any one of the key columns of the non-clustered index.
Method 3
Use DBCC DBREINDEX. DBCC DBREINDEX sets the correct value for the null-block column.
Method 4
Determine the dynamic cursor position with an order-by clause. Now, only the key columns of the index are compared instead of the whole index row.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
