title: How to get query plan for a running process in mysql
body: <p>I can see currently running processes using <code>show processlist;</code>. It gives me partial text of the query which is running.
  I want to know how can I see the query plan for this process using the Id.</p>
  
  <p>"Explain" command of mysql accepts table name or a full query, but it doesn't accept a running query's id.</p>
