What I wrote with HAVING doesn't do any difference - replace back to WHERE.
Your query is OK.
Try: echo mysql_error();
And try to remove the condition "WHERE admin.user..." if that outputs anything.

Thanks Martin, oddly enough that still doesn't pull any results, it won't even print the variables if I try to list them to see, I know my db connection is good checked that, and can do really simple queries, would something be preventing a JOIN from working? When I Reveal my variables this query snippet:$sql = "SELECT admin.AdminID, workorders.WorkOrderIDFROM admin INNER JOIN workorders ON admin.AdminID=workorders.AdminID HAVING admin.username='".$_SESSION['user']."' ";$result2 = mysql_query ($sql); $row2 = mysql_fetch_assoc ($result2); $Total = ceil(mysql_num_rows($result2)/$PerPage);Returns this: $sql"SELECT admin.AdminID, workorders.WorkOrderID FROM admin INNER JOIN workorders ON admin.AdminID=workorders.AdminID HAVING admin.username='tmiller' "$result2""$row2"" Terion On Thu, Jan 29, 2009 at 11:56 AM, Martin Zvarík <mzvarik@gmail.com> wrote:This will work: $sql = " SELECT admin.AdminID, workorders.WHAT_YOU_WANT FROM admin INNER JOIN workorders ON admin.AdminID=workorders.AdminID HAVING admin.username='".$_SESSION['user']."'

What I'm trying to do is match up AdminID's from two tables and display only that users orders, sounds simple enough right...but I can't get it to return the AdminID... My Query: $sql =-- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php"SELECT admin.AdminID , workorders.AdminID FROM admin INNER JOIN workorders ON (admin.AdminID=workorders.AdminID) WHERE admin.UserName = '".$_SESSION['user']."' ";$result = mysql_query ($sql); $row = mysql_fetch_assoc ($result); $Total = ceil(mysql_num_rows($result)/$PerPage);Thanks for any tips on how else I can accomplish this... Terion
