Or perhaps something like this:
WITH Regions (Region) AS (
SELECT 'north' UNION ALL SELECT 'south')
SELECT region=CASE Region WHEN 'north' THEN 2 WHEN 'south' THEN 3 END
FROM Regions
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
