Re: [PHP] Query for two fields with the same name
Maybe something like this : $connection = SELECT t2.id AS idtwo, t1.id AS idone FROM connection AS t1, pr AS t2 WHERE t1.area_id = '$gateway_link' AND t1.pr_id = t2.id; This is probably a simple question, but I can't seem to find the answer online. I'm using this query: $connection = select * from connection, pr WHERE connection.area_id = '$gateway_link' and connection.pr_id = pr.id; Both tables have a field called ID but they have different information in them. $row['id'] gets me the one from the table called pr but I need to call the ID from the table connection. -- Kevin Murphy Webmaster: Information and Marketing Services Western Nevada Community College www.wncc.edu 775-445-3326 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You have now stumbled into ONE of many reasons why SELECT * is just Bad Code. :-) Figure out which fields you REALLY need and specify them by name in place of * In addition, to actually solve your problem, you'll be able to do something like: SELECT pr.id as pr_id, connection.id as connection_id, area_id, ... You can useas XYZ to sort of rename any column you want on the fly, and that is what it will be called. It's also really handy when you have formulas in your select: SELECT (x.size + y.size) as sum, x.id, y.id from x, y ... Without the as sum $row['something goes here'] will have your sum answer, but what will it be called? I don't even know the answer to that one, cuz whatever it is, it's just too painful compared to using 'sum' -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

NOT a php question. Kevin Murphy wrote: This is probably a simple question, but I can't seem to find the answer online. I'm using this query: $connection = select * from connection, pr WHERE connection.area_id = '$gateway_link' and connection.pr_id = pr.id; doing SELECT * FROM bla is not recommended, better to actually specify _just_ the fields you need. SELECT c.id AS cid, p.id AS pid FROM connection AS c, pr AS p WHERE ... this stuff can be found in the mysql docs.
