Hi
I have a mysql database that contains numeric values.

Example :

affID l Amount

MW001 5
MW004 10
MW001 11
MW001 15
MW004 20

What i need is help on a query that will caluculate the Total Amount for the affID MW001.

So for example : MW001 = 31

At the moment it gets the value of the affID through a login session.

this is what i have and it is not working :

$sql = "SELECT affID, COUNT(*) as c FROM taffiliate WHERE AffCommision = '" . $_SESSION['affID'] . "'";
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
echo $row['c'] ;

Solution 1

I'm not sure of mySQL itself, but ANSI SQL would be:

SELECT SUM(Amount)
FROM taffiliate
WHERE affID = 'MW001'

try this

PHP

$sql="SELECT  SUM(amount)as sum  FROM `taffiliate` WHERE affid='MW001'";

$result=  mysqli_query($con, $sql) or die(mysqli_error($con));




    while ($row=  mysqli_fetch_array($result))
    {
        $y= $row['sum'].'<br>';


    }

you can use where condition as you want i just gave one example, for MW001, the total will be 31
