There's no need to use dynamic code. Here's one option and maybe someone could give a better one because I'm not so sure on its performance with big loads. It's quite simple though. 🙂
SELECT MYID,
TITLE
FROM #Temp
GROUP BY MYID,
TITLE
HAVING COUNT(*) = (SELECT COUNT( DISTINCT ID) FROM #Temp)
ORDER BY MYID,
TITLE
+1
Unless of course you allow duplicates in your table, like the last row in the following:
INSERT INTO #Temp
Select 1, 1, 'First' UNION ALL
Select 1, 2, 'Second' UNION ALL
Select 1, 3, 'Third' UNION ALL
Select 1, 4, 'Fourth' UNION ALL
Select 1, 5, 'Fifth' UNION ALL
Select 1, 6, 'Sixth' UNION ALL
Select 1, 7, 'Seventh' UNION ALL
Select 1, 8, 'Eighth' UNION ALL
Select 1, 9, 'Ninth' UNION ALL
Select 1, 10, 'Tenth' UNION ALL
Select 2, 3, 'Third' UNION ALL
Select 2, 4, 'Fourth' UNION ALL
Select 2, 5, 'Fifth' UNION ALL
Select 2, 6, 'Sixth' UNION ALL
Select 2, 7, 'Seventh' UNION ALL
Select 2, 8, 'Eighth' UNION ALL
Select 2, 9, 'Ninth' UNION ALL
Select 3, 1, 'First' UNION ALL
Select 3, 2, 'Second' UNION ALL
Select 3, 3, 'Third' UNION ALL
Select 3, 4, 'Fourth' UNION ALL
Select 3, 5, 'Fifth' UNION ALL
Select 3, 6, 'Sixth' UNION ALL
Select 3, 7, 'Seventh' UNION ALL
Select 3, 8, 'Eighth' UNION ALL
Select 3, 8, 'Eighth';
I believe what Luis has done could be modified for this case, but I'll leave that to you if you say it can happen.
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.
