To stop a running query you should use the SQL command KILL QUERY processid.

Returns TRUE on success or FALSE on failure.

Examples

Example 1525. Object oriented style

<?php
$mysqli
= new mysqli("localhost", "my_user", "my_password", "world");

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

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

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

/* This should produce an error */
if (!$mysqli->query("CREATE TABLE myCity LIKE City")) {
   
printf("Error: %s\n", $mysqli->error);
   exit;
}

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


Example 1526. Procedural style

<?php
$link
= mysqli_connect("localhost", "my_user", "my_password", "world");

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

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

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

/* This should produce an error */
if (!mysqli_query($link, "CREATE TABLE myCity LIKE City")) {
   
printf("Error: %s\n", mysqli_error($link));
   exit;
}

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


The above example will output:

Error: MySQL server has gone away
