This is relatively easy: SELECT rowID, COUNT( rowID ) -1 AS countrepeat FROM <tablename> WHERE theDate < CONCAT(DATE_FORMAT(CURDATE(), '%Y-%m-'), '01') AND theDate >= CONCAT(DATE_FORMAT(CURDATE(), '%Y-%m-'), '01') - INTERVAL 1 MONTH GROUP BY rowID HAVING countrepeat >0 See if I have time for #2 later...
