Example #1 cubrid_data_seek() example


<?php
$conn = cubrid_connect("127.0.0.1", 33000, "demodb");

$req = cubrid_execute($conn, "SELECT * FROM code");
cubrid_data_seek($req, 0);

$result = cubrid_fetch_row($req);
var_dump($result);

cubrid_data_seek($req, 2);
$result = cubrid_fetch_row($req);
var_dump($result);

cubrid_data_seek($req, 4);
$result = cubrid_fetch_row($req);
var_dump($result);
