You are probably better off using a Tally table for this:
CREATE TABLE #TempBet
(High int, Low int)
INSERT INTO #TempBet (Low, High)
SELECT 1, 3 UNION ALL
SELECT 2, 3 UNION All
SELECT 5, 8
;WITH Tally (n) AS (
SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY (SELECT NULL))
FROM sys.all_columns t1 CROSS JOIN sys.all_columns t2)
SELECT High, Low, Bet=n
FROM #TempBet
CROSS APPLY (
SELECT n
FROM Tally
WHERE n BETWEEN Low AND High) a
DROP TABLE #TempBet
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.
Need to UNPIVOT? Why not CROSS APPLY VALUES instead?[/url]
