# maxdb_data_seek

# result->data_seek

(PECL maxdb >= 1.0)

maxdb_data_seek -- result->data_seek — Adjusts the result pointer to an arbitary row in the result

### Opis

Procedural style:

bool maxdb_data_seek ( resource `$result` , int `$offset` )

Object oriented style (method):

result
bool data_seek ( int `$offset` )

The maxdb_data_seek() function seeks to an arbitrary result pointer specified by the `offset` in the result set represented by `result` . The `offset` parameter must be between zero and the total number of rows minus one (0..maxdb_num_rows() - 1).

### Zwracane wartości

Zwraca `TRUE` w przypadku powodzenia, `FALSE` w przypadku błędu.

### Przykłady

Przykład #1 Object oriented style

`<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, state FROM hotel.city ORDER BY name";
if ($result = $maxdb->query( $query)) {
/* 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();
?>`

Przykład #2 Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (!$link) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, state FROM hotel.city ORDER BY name";
if ($result = maxdb_query($link, $query)) {
/* seek to row no. 400 */
maxdb_data_seek($result, 10);
/* fetch row */
$row = maxdb_fetch_row($result);
printf ("City: %s State: %s\n", $row[0], $row[1]);
/* free result set*/
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

Powyższy przykład wyświetli coś podobnego do:

    City: Irvine  State: CA
