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 DescriptionProcedural 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
如果成功则返回 TRUE，失败则返回 FALSE。
Example例子 1. Object oriented style |
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
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)) {
$result->data_seek(10);
$row = $result->fetch_row();
printf ("City: %s State: %s\n", $row[0], $row[1]);
$result->close();
}
$maxdb->close();
?>

例子 2. Procedural style |
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
if (!$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, $query)) {
maxdb_data_seek($result, 10);
$row = maxdb_fetch_row($result);
printf ("City: %s State: %s\n", $row[0], $row[1]);
maxdb_free_result($result);
}
maxdb_close($link);
?>

The above examples would produce the following output:
