/* seek to row no. 10 */
$result->data_seek(10);
/* fetch row */
$row = $result->fetch_row();
printf ("City: %s State: %s\n", $row[0], $row[1]);
/* free result set*/
$result->close();
}
/* close connection */
$maxdb->close();
?>

}
$query = "SELECT name, state FROM hotel.city ORDER BY name";
if ($result = maxdb_query($link, $query)) {
/* seek to row no. 400 */
maxdb_data_seek($result, 10);
/* fetch row */
$row = maxdb_fetch_row($result);
