valajio Posted December 22, 2009 Share Posted December 22, 2009 Hello, some of the simplest things in code are the hardest for me... I've done this before but I can't remember how. I have a mysql loop that fetches information from a table based on the username and then a loop inside of that one that fetches matches to the results based on an entry id... the problem is that the matching results are duplicated under under every match in the loop... please help? $queryb = "SELECT * FROM database.field WHERE author = '".$user."' ORDER BY time DESC LIMIT 8"; $query_resultb = @mysql_query ($queryb) OR error(mysql_error(), __LINE__, __FILE__, 0, '', ''); while($infob = @mysql_fetch_array($query_resultb)) { $eid = $infob['eid']; $entry = info[*]; heres the matches... then I have another loop $queryc = "SELECT * FROM database.comments WHERE id='".$eid."' ORDER BY time DESC LIMIT 2"; $query_resultc = @mysql_query ($queryc) OR error(mysql_error(), __LINE__, __FILE__, 0, '', ''); while($infoc = @mysql_fetch_array($query_resultc)) { matches found here repeat for every $entry match above on the page inside the 1st loop?? } } I know this is a really easy fix... but I'm better at harder stuff when it comes to coding and always forget the simplest things that should just become second nature! I'm sure alot of other people have the same issues!

trq Posted December 22, 2009 Share Posted December 22, 2009 There is a tutorial on our main site on using mysql joins and unions, you should read it. Executing queries within loops is very inefficient when you can get all your data in one query.
