 }

$sql = "SELECT Lastname FROM Persons ORDER BY LastName;";
 $sql .= "SELECT Country FROM Customers";

// Execute multi query
if (mysqli_multi_query($con,$sql))

 if ($result=mysqli_store_result($con))
 {
 while ($row=mysqli_fetch_row($result))
 {
 printf("%sn",$row[0]);
 }
 mysqli_free_result($con);
 }
 }
 while (mysqli_next_result($con));
