LEARN ABOUT PHP
maxdb_data_seek
MAXDB_DATA_SEEK(3) 1 MAXDB_DATA_SEEK(3)
maxdb_data_seek - Adjusts the result pointer to an arbitary row in the result
Procedural style
SYNOPSIS
bool maxdb_data_seek (resource $result, int $offset)
DESCRIPTION
Object oriented style
bool maxdb_result::data_seek (int $offset)
The maxdb_data_seek(3) 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(3) - 1).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #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
", 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
", $row[0], $row[1]);
/* free result set*/
$result->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (!$link) {
printf("Connect failed: %s
", 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
", $row[0], $row[1]);
/* free result set*/
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
City: Irvine State: CA
