Best groupmember, I am doing this query that works fine.
SELECT tps.tour_player_id, sum(if(tsh.hole_number<=9, tps.strokes, '0')) AS 'front_9', sum(if(tsh.hole_number>=10, tps.strokes, '0')) AS 'back_9', sum(tps.strokes) AS 'score' FROM tour_player_score tps INNER JOIN tour_scorecard_hole tsh ON tps.scorecard_hole_id=tsh.id GROUP BY tps.tour_player_id ORDER BY score, back_9; However, I would like to just get the result where sum(tps.strokes)<90, so I added WHERE sum(tps.strokes)<90 after the inner join like this SELECT tps.tour_player_id, sum(if(tsh.hole_number<=9, tps.strokes, '0')) AS 'front_9', sum(if(tsh.hole_number>=10, tps.strokes, '0')) AS 'back_9', sum(tps.strokes) AS 'score' FROM tour_player_score tps INNER JOIN tour_scorecard_hole tsh ON tps.scorecard_hole_id=tsh.id WHERE sum(tps.strokes) < 90 GROUP BY tps.tour_player_id ORDER BY score, back_9; It gives me error 1111: Invalid use of group function Where does the error come from? And how would I solve this? Best regards, Peter Lauri -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
