title: How to clear MySQL query profiles
body: <p>After turning on profiling in MySQL</p>
  
  <pre><code>  SET profiling=1;
  </code></pre>
  
  <p>I can run like a query like <code>SELECT NOW();</code>  and see profile results with it's execution time using:</p>
  
  <pre><code>  SHOW PROFILES;
  </code></pre>
  
  <p>However, I can't figure how to clear out the profile listing.  Anyone know the statement to delete old profile data? <code>SET profiling=0;</code> just disables logging of new data and doesn't remove old stats.</p>
