To start with, the result set you get in MySQL is probably not the result set you are looking for because the SQL you have here is not logical. You are asking for U.User_ID to be returned from WMS_User but you are not including that table in the where clause so you are going to get every row in that table returned. You are also including a table WMS_Projects that is not anywhere in the Select or Where clause. I would suggest to trim down your SQL to only contain tables A and B then add back in the other tables once you add the proper code in the where clause to link them into the first query. Execute this SQL on your database and see if you get fewer rows returned: SELECT A.*, B.* FROM WMS_Allocations A, WMS_Bookings B WHERE A.User_ID = B User_ID AND A.User_ID = '1' AND B.Booking_Start_Date >= '2003-04-28' AND B Booking_End_Date <= '2003-04-29'; Jim -------Original Message------- From: shaun Date: Tuesday, April 22, 2003 10:35:36 AM To: php-db@lists.php.net Subject: Re: Bizzare Error sorry, here it is: num = 0 query = SELECT A.*, B.*, U.User_ID FROM WMS_Allocations A, WMS_Bookings B, WMS_User U, WMS_Projects P WHERE A.User_ID = B.User_ID AND A.User_ID = '1' AND B.Booking_Start_Date >= '2003-04-28' AND B.Booking_End_Date <= '2003-04-29' when this query is entered directly to mysql there are lots of rows, i dont understand this at all!
