maxdb_data_seek

Adjusts the result pointer to an arbitary row in the result (PECL)
bool maxdb_data_seek ( resource result, int offset )

Procedural style:

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).

Return values

如果成功则返回 TRUE,失败则返回 FALSE

Example

例 981. 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();
?>

例 982. 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);
?>

The above examples would produce the following output:

City: Irvine  State: CA
