maxdb_thread_id

(PECL)maxdb_thread_id

(no version information, might be only in CVS)maxdb->thread_id -- Returns the thread ID for the current connection

Description

Procedural style:int maxdb_thread_id ( resource link )


Object oriented style (property):class maxdb {


int thread_id


}

- The maxdb_thread_id() function returns the thread ID for the current connection which can then be killed using the maxdb_kill() function. If the connection is lost and you reconnect with maxdb_ping(), the thread ID will be other. Therefore you should get the thread ID only when you need it.

Замечание: The thread ID is assigned on a connection-by-connection basis. Hence, if the connection is broken and then re-established a new thread ID will be assigned.

Return values

- maxdb_thread_id() returns the Thread ID for the current connection.

- maxdb_kill()

Example

Пример 1. Object oriented style

<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}

/* determine our thread id */
$thread_id = $maxdb->thread_id;

/* Kill connection */
$maxdb->kill($thread_id);

/* This should produce an error */
if (!$maxdb->query("CREATE TABLE mycity LIKE hotel.city")) {
printf("Error: %s\n", $maxdb->error);
exit;
}

/* close connection */
$maxdb->close();
?>

Пример 2. Procedural style

<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}

/* determine our thread id */
$thread_id = maxdb_thread_id($link);

/* Kill connection */
maxdb_kill($link, $thread_id);

/* This should produce an error */
if (!maxdb_query($link, "CREATE TABLE mycity LIKE hotel.city")) {
printf("Error: %s\n", maxdb_error($link));
exit;
}

/* close connection */
maxdb_close($link);
?>

- The above examples would produce the following output: 
Warning: maxdb_query(): -10821 Session not connected <...>

Error: Session not connected
