$offset
) : bool
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).
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 Objektorientierter Stil
<?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();
?>
Beispiel #2 Prozeduraler Stil
<?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);
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
