 }
 
 mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
 mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");
 
 
 $query = "SELECT Name, Code FROM myCountry ORDER BY Name";
 if ($stmt = mysqli_prepare($link, $query)) {
 
 /* drop table */
 mysqli_query($link, "DROP TABLE myCountry");
