$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
if ($stmt = mysqli_prepare($link, $query)) {
 
    /* execute query */
    mysqli_stmt_execute($stmt);
 
    /* bind result variables */
    mysqli_stmt_bind_result($stmt, $name, $code);
 
    /* store result */
    mysqli_stmt_store_result($stmt);
 
    /* seek to row no. 400 */
    mysqli_stmt_data_seek($stmt, 399);
 
    /* fetch values */
    mysqli_stmt_fetch($stmt);
 
    printf ("City: %s  Countrycode: %s\n", $name, $code);
 
    /* close statement */
    mysqli_stmt_close($stmt);
