O.K. you SQL gurus-- I have a difficult query for you that has me stumped. The table has two columns: rowID (MEDIUMINT-but *NOT* AUTO_INCREMENT) and theDate (DATETIME). I need it to find:
1. The COUNT of REPEATED instances of the rowID in the last month. - so if there are 5 rows with the same rowID in the last month, it would return "4" (I can only seem to get it to return "10" WHERE t1.rowID = t2.rowID AND t1.theDate > t1.theDate) 2. The AVERAGE number of REPEATED instances of the rowID per week (Monday 00:00:00 through Monday 00:00:00 one week later) in the last month. If I need to add table columns I certainly can.
