[PHP-DB] Idea as to why this query won't work as expected?
Hi All, I have a query like: select * FROM OrderTable WHERE submitted=1 AND dateinserted='1036386000' AND dateinserted='1036502796' AND order_status='Shipped' OR order_status='Not Shipped' Now.. if I omit the AND order_status='Shipped' OR order_status='Not Shipped' part the query works fine and only returns 2 results (as expected). However, with the inclusion of the previous I get all the results (currently 8) returned. It seems to be ignoring everything before AND order_status='Shipped' OR order_status='Not Shipped'. Any clues? Much thanks! Aaron

AND/ OR precedence mistake. Your query will return all the rows for which order_status='Not Shipped' Probably what you want is: select * FROM OrderTable WHERE submitted=1 AND dateinserted='1036386000' AND dateinserted='1036502796' AND ( order_status='Shipped' OR order_status='Not Shipped' ) HTH Ignatius J.

Try grouping your WHERE clauses with parentheses like so: select * FROM OrderTable WHERE ( submitted=1 AND dateinserted='1036386000' AND dateinserted='1036502796' AND order_status='Shipped' ) OR order_status='Not Shipped' I can never remember whether SQL is left-to-right, right-to-left, or some other deviant. Using parens is a sure way to guarantee that your statements are processed in the order you desire. --Dave Aaron Wolski wrote: Hi All, I have a query like: select * FROM OrderTable WHERE submitted=1 AND dateinserted='1036386000' AND dateinserted='1036502796' AND order_status='Shipped' OR order_status='Not Shipped' Now.. if I omit the AND order_status='Shipped' OR order_status='Not Shipped' part the query works fine and only returns 2 results (as expected).

The or part should be in parens. Your bascialy saying grab everything that has order_status='Shipped' and your date requirements, OR everything where order_status is equal to 'Not Shipped'... -- Josh -Original Message- From: Aaron Wolski [mailto:aaronjw;martekbiz.com] Sent: Tuesday, November 05, 2002 9:00 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] Idea as to why this query won't work as expected?

Multiplications are done before additions, so ANDs are done before ORs. Thomas -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
