body: <p>How can I update 2 columns at a time?</p>
  
  <p>I tried the following statement, which doesn't work:</p>
  
  <pre><code>UPDATE exercises
  SET times_answered = times_answered + 1
  AND av_answeringTime = av_answeringTime + ( (av_answeringTime / (times_answered) ) + ?) * (times_answered + 1)
  WHERE name = ?
  </code></pre>
