maxdb_data_seek
(PECL)
maxdb_data_seek
(no version information, might be only in CVS)
result->data_seek -- Adjusts the result pointer to an arbitary row in the result
Description
Procedural style:
bool
maxdb_data_seek ( resource result, int offset )
Object oriented style (method):
class
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).
Return values
Zwraca TRUE w przypadku sukcesu, FALSE w
przypadku porażki.
Example
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);
?>
