อยากจะ update ข้อมูล แต่ติดเรื่อง select count ตอน update แก้ไขข้อมูลเดิม

     $sql = "select count(*) as countrow from flowmail where femail = $femail and access = $access ";  
     $result = mysql_query($sql) or exit($sql);
     $row = mysql_fetch_array($result);

     if ($row['countrow'] >0)
        exit("<script>alert('Please change femail and access There only 1 person');history.back();</script>");

    $sql1 = "update flowmail set
            femail  = '$femail ',
            access = '$access'
            where id = '$id'";

  mysql_query($sql1) or die(mysql_error());
  
  echo "<script>alert('Update Complete');window.location='showlist.php';</script>";

   if ($row['countrow'] >0)
      exit("<script>alert('Please change femail and access There only 1 person');history.back();</script>");

$sql1 = "update flowmail set
          femail  = '$femail ',
          access = '$access'
          where id = '$id'";

  $id = $_POST['id'];  // id=3
  $femail = $_POST['femail'];  // femail=02
  $access = $_POST['access'];  // access=003

   $sql = "select count(*) as countrow from flowmail where femail = $femail and access = $access ";  
   $result = mysql_query($sql) or exit($sql);
   $row = mysql_fetch_array($result);

   if ($row['countrow'] >0)
      exit("<script>alert('Please change femail and access There only 1 person');history.back();</script>");

  $sql1 = "update flowmail set
          femail  = '$femail ',
          access = '$access'
          where id = '$id'";

mysql_query($sql1) or die(mysql_error());

echo "<script>alert('Update Complete');window.location='showlist.php';</script>";
