Hello Brian,
I have to apologize as I did not type the connecting clause A to B on
storenumber
> SELECT a.storenumber,a.storename FROM $customer a LEFT JOIN $customer b on
> a.id=b.id AND b.storenumber in ('$storenumberlist') where b.storenumber is
> null
SELECT a.storenumber,a.storename
FROM $customer a
LEFT JOIN $customer b
ON a.id=b.id
AND a.storenumber = b.storenumber
AND b.storenumber in ('$storenumberlist')
WHERE b.storenumber is null
