I'm afraid, no. Maybe I'm too tired right now but "select a bunch of data" is not very precise. It is especially unclear to me whether you need the "bunch" only for counting purposes or are interested in the result as well.

Also, your remark "based on the results of the original select" might indicate that you have a too procedural view of SQL.

Maybe. Can you try to explain more elaborately what you have as input and expect as output?

Kind regards
