I have the following query

  select UID FROM RaceCDC WHERE HierarchicalCode =
  (Select LEFT(HierarchicalCode,2)
   FROM RaceCDC WHERE Concept = 'Payson Apache')

What I want to do is to return NULL when the second select fails to find a match. So if 'Payson Apache' isn't in the table I want the complete statement to return NULL.

Can someone show me how to do this?
