Sometimes it is easier to simply read the table into an array and perform array operations after the MySQL query versus trying to do all the processing with a MySQL query.

I advise you to simplify the query, read the data into an array, and get the data you need by operating on the array, presumably in PHP.

Are you programming this in PHP?
