Recordset total record count problem using LEFT OUTER JOIN

Hi i'm having an issue with the display total records count, it displays 18 records from one table and 3 from the other doing a LEFT OUTER JOIN, this should come to 21 but displays 18, I've included screenshots showing the count and SQL recordset, I've tried grouping by logs.id and eventlog.id but returns 1 in the count, any help will be much appreciated, I don't know if i'm just missing something in the SQL statement or whether it's a problem with the MySQLi behaviours extension.

The parameters i'm using $qget is just isset $_GET['q'] just in a customised variable form

Many thanks
Michael

A left join won't necessarily show the combined rows in the result. I'm thinking your SQL statement is wrong, but I'm not sure exactly what you are trying to achieve, so I can't comment on how to improve it.

Maybe try displaying the final SQL statement with:
<?php
echo($combinedlogs->debugSQL());
?>

Than you can cut and paste that into phpMyAdmin and see the full results and try to figure out what query returns the actual results you expect or need. I could help with this in a premier support ticket, but I'd need to have a conversation with you to figure out what you are trying to do and see it in context to figure out what the right SQL statement is.

Thanks for the reply, the debug code helped, it returned 18 so the WebAssist code is correct, I guess I just can't count the extra records using a left join, you were correct the main SQL code was wrong, I've corrected that now, thanks, the problem still exists with what I'm trying to do but I can settle by ordering by logs.id I have two log tables that I was trying to join together but could only join on id for both anything else I tried returned multiple records over and over again, so I joined on id and wanted to order by logs.date on the left table with the records being affected on the right, but having tried everything I don't think it's possible but id will do, many thanks for your help it was much appreciated
