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

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Example

Пример 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();

?>

Пример 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);

?>
