Jessica Posted July 10, 2006 Share Posted July 10, 2006 I am performing this query:$update_item = "UPDATE stall_transactions SET cleared = 1 WHERE stall_id = $stall_id LIMIT 50";I want it to update the 50 most recent by either sold (datetime) or transaction_id (primary key). How can I ensure it does the 50 most recent?Thanks!ps: the new forum design is awesome!

designationlocutus Posted July 10, 2006 Share Posted July 10, 2006 Baffled me for a minute, but I was sure it was possible, so I had a look over at mysql.com.The following is the syntax for UPDATE. As long as you get the order correct, I'm sure you will have no problems.[code]UPDATE [LOW_PRIORITY] [IGNORE] tbl_name SET col_name1=expr1 [, col_name2=expr2 ...] [WHERE where_condition] [ORDER BY ...] [LIMIT row_count][/code] Link to comment https://forums.phpfreaks.com/topic/14177-how-to-order-in-update-when-using-limit-by/#findComment-55562 Share on other sites More sharing options...
fenway Posted July 10, 2006 Share Posted July 10, 2006 Yup... just add the necessary ORDER BY clause and you're set. Link to comment https://forums.phpfreaks.com/topic/14177-how-to-order-in-update-when-using-limit-by/#findComment-55641 Share on other sites More sharing options...
