Return true in ExecuteSQL could be a confusing point

if($this->records > 0){
                         $this->ArrayResults();
                         return $this->arrayedResult;
                        }else{
                         return true;
                        }

When we use ExecuteSQL, commonly here we can't use :

$ret = $db->ExecuteSQL (....);
if (empty($ret)) {
}

coz it's always "TRUE", so you don't know it's empty.
