You should take a look at this article

Most in here would say you want to unpivot the table :-D

:-P:-P I was going to say that! HeheHehe


My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

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?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!

Without seeing your query, it's impossible to tell what the best approach may be. The previous posts will certainly work, but it's entirely possible that your original query may be doing on unnecesary pivot or crosstab and removing that pivot/crosstab will solve your problem.
