maxdb_thread_id
maxdb::thread_id
(PECL maxdb >= 1.0)
maxdb_thread_id -- maxdb::thread_id — Returns the thread ID for the current connection
Description
Procedural style
$link
) : intObject oriented style
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.
Note:
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.
Examples
Example #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();
?>
Example #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 example will output something similar to:
Warning: maxdb_query(): -10821 Session not connected <...> Error: Session not connected
