maxdb_data_seek

result->data_seek

(No version information available, might be only in CVS)

result->data_seek — Adjusts the result pointer to an arbitary row in the result

说明

Procedural style:

bool maxdb_data_seek ( resource $result , int $offset )

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).

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

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\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();
?>

Example#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);
?>

The above examples would produce the following output: 

City: Irvine  State: CA
