Strange - I'm sure I wrote a message here...

Did I forget to post?

Anyway, one more time - using the derived table is the correct approach for this problem, since TOP clause applies to the first select and then the second select (from UNION ALL part) brings all records satisfying the condition.

If it's not broken, fix it until it is.
