First of all I want to confirm that you are actually using sql 2000.
I can't use CTE, TEMP Tables or SPs, I have to resolve this in the SELECT query (I can use subqueries).
This is a rather strange requirement. If you are truly using sql 2000 then I understand the restriction on cte since they didn't exist yet. No temp table or SP sounds like an artificial restriction that is often found in homework assignments.
