RE: T-SQL puzzler - given a cell in an N-dimensional space, return the cells that are inline with the given cell along each axis

I'm not sure if I am understanding the requirements for this correctly, but would this work?declare @cellid int = 1;select *

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?

RE: Summarize data over contiguous date ranges
Perhaps you can explain how you expect to "condense" overlapping periods in ID=1 from 5 rows to 6 rows (sample data vs. expected results)?

RE: Calculate Differences and move differences into Next Month

It would probably be a lot faster than what you settled on.
