ON DUPLICATE KEY..."Table logs:id: INT(11) auto_increment primary keysite_id: INT(11)time: DATEhits: INT(11)Then: CREATE UNIQUE INDEX comp ON logs (`site_id`, `time`); And then you can: INSERT INTO logs (`site_id`, `time`,`hits`) VALUES (1,"2004-08-09", 15) ON DUPLICATE KEY UPDATE hits=hits 15; Excellent feature, and it is much faster and briefer then using first a select, then issuing either an update or an insert depending on the value of the select.You also get rid of the probably necessary table-lock during this action.
