No, it's just the script. I figure if you don't already have a CLR library, you probably aren't interested anyway. As far as performance goes it should be pretty linear - it's not doing the grouping of things into months (or whatever period you prefer). It's just to remove the drudgery of writing all those PIVOTS.

You give it some data, it groups by the string fields, pivots the date field (there can only be one), and sums the numeric fields.

You didn't think I'd be THAT helpful, did you? :w00t:
