title: MySQL double sort
body: <p>I would like to double sort my user list. Is this possible within one MySQL query?</p>
  
  <ol>
  <li>Sort by <code>activity</code></li>
  <li>Sort by <code>ID</code></li>
  </ol>
  
  <p>For example:</p>
  
  <pre><code>1  Jack   Active 
  2  Jill   Active 
  5  Jens   Active  
  3  Harry  Inactive 
  4  Larry  Inactive 
  6  Luke   Inactive
  </code></pre>
