Mysql Kill Process __link__ Jun 2026

Before you can kill a process, you need to find it. MySQL provides a built-in command to view all active threads.

-- 1. Kill the query only KILL QUERY 123;

-- Kill the blocking connection (not just query) KILL CONNECTION <blocking_id>; mysql kill process

Often, the Info column in the basic view is too short to see the full query. To see the complete query text without truncation, use:

: Use KILL QUERY first, then wait for thread to disappear. Before you can kill a process, you need to find it

Killing a query does instantly release metadata locks. The lock is held until the kill acknowledgement completes. This can cause cascading blocking:

: This is the standard command to see all active connections, including the user, host, database, command type (e.g., Query , Sleep ), time running, and the actual SQL text. Kill the query only KILL QUERY 123; --

In MySQL, "killing a process" refers to terminating a specific client thread or a running query. The process involves identifying the problematic thread and then issuing a command to stop it.
