Okay so this has been modified there is still 3 tables board, account, log

Thanks to Bryan Moyles he kind of give me an epiphany

here’s my code

$query=$S->query("
    SELECT
        `TBL`.`LAcc`,
        `TBL`.`AId`,
        `TBL`.`Add`,
        `TBL`.`Lost`,
        `TBL`.`LDate`,
        `TBL`.`FDate`

        FROM (
            SELECT 
                (SELECT SUM(`Add`) FROM `m_rules` GROUP BY `Group`) AS `Add`,
                `S`.`Account` as `LAcc`,
                `P`.`Id` as `AId`,
                SUM(`S`.`Loss`*`S`.`Multiple`) AS `Lost`,
                MAX(`S`.`Timestamp`) AS `LDate`,
                MIN(`S`.`Timestamp`) AS `FDate`
                    FROM `log` AS S,`account` AS P

            GROUP BY `P`.`Id`
        ) as `TBL`
        WHERE `TBL`.`FDate` <= NOW()
        AND `TBL`.`LDate` >= DATE_SUB(NOW(), INTERVAL 1 DAY)

") or die(mysql_error());

    while($Log=$S->fetch($query)) { 

        if($Log['AId']==$Log['LAcc']) {
            $Score=$Log['Add']-$Log['Lost'];
        } else {
            $Score='Bonus';
        }

        /*
            echoing to see results
        */
        echo $Log['AId'].' : '.$Score.'<br />';

        /* 
        This is what the query would look like Thanks to Bryan Moyles,

        $S->query("INSERT INTO `board` (`Account`,`Score`, `Date`)VALUES('".$Log['Id']."', '".$Score."', 'NOW()') ON DUPLICATE KEY UPDATE Score = '".$Score."'");
        */
    }

Here you go all results: Group by Account ID

GROUP BY Log Account ID

I see the problem just not sure of the solution..

SOLVED!

I replaced 

FROM `log` AS S,`account` AS P

With

FROM `account` AS `P` LEFT JOIN `log` AS `S` ON `P`.`Id`=`S`.`Account`

in the original query (before I modified and changed it on here) I had the account and log in reverse along with the P.Id=S.Account which didn’t work so I just swapped log and account around and it works.. can’t believe that was the issue but thank you for the help.

    I’m not sure how you would ever come across a situation where the log didn’t exist, being that you’re building your data off of the results of a query. However, you’re inserting the primary key, and you can catch the duplicate key error, and run an update accordingly.

    Check out this article
    http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html

    $S->query("INSERT INTO `board` (`Account`,`Score`, `Date`)VALUES('".$Log['Id']."', '".$Score."', 'NOW()') ON DUPLICATE KEY UPDATE Score = '".$Score."'");
