You might want to look into using the CROSS APPLY VALUES approach to UNPIVOT (see the first article in my signature links). I find it much more readable that multiple UNPIVOTs and it seems to perform better as well.
No loops! No CURSORs! No RBAR! Hoo-uh!
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?
Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Are you too recursively challenged?
Splitting strings based on patterns can be fast!
