SELECT CONCAT('KILL ', id, ';') FROM information_schema.processlist WHERE time > 300; Sometimes you run KILL but the query remains in the process list with a state like Killed or Checking table . This means MySQL has acknowledged the kill command but is waiting for an internal resource (e.g., disk I/O, row lock) to release.

However, "killing" a MySQL query is not without risk. This piece covers how to do it, when it’s safe, and the potential consequences. Before you can kill a query, you need its Process ID (Thread ID) . Connect to MySQL via the command line or your admin interface and run:
| Command | Effect | | :--- | :--- | | KILL QUERY 12345; | Terminates the but keeps the connection open. | | KILL CONNECTION 12345; (or just KILL 12345 ) | Terminates the query and closes the connection. |
