I'm trying to update multiple rows in one table in MySQL database by doing this. And its not working.
$query = "UPDATE cart SET cart_qty='300' WHERE cart_id = '21';
UPDATE cart SET cart_qty='200' WHERE cart_id = '23';
UPDATE cart SET cart_qty='100' WHERE cart_id = '24';";
mysql_query($query,$link);// $link is specified above
Anyone know what is wrong with this.
