    $sql = "SELECT productname
    FROM exportorder
    GROUP BY productname
    HAVING count(*) > 1;";
    $result = mysqli_query($mysqli, $sql);


    $sql1 = "SELECT productname,
                    sum(pieceexport) as total 
                    FROM exportorder where factory='โรงงาน1' and smonth = '$month'
                    GROUP BY productname";
    $result1 = mysqli_query($mysqli, $sql1);


    $sql2 = "SELECT productname,
                    sum(pieceexport) as total 
                    FROM exportorder where factory='โรงงาน2' and smonth = '$month'
                    GROUP BY productname";
    $result2 = mysqli_query($mysqli, $sql2);

    $sql3 = "SELECT productname,
