title: DELETE old rows from Mysql General Log Table (MyISAM not CSV)
body: <p>I wanted to delete old rows from my <code>mysql.general_log</code> table but ran into this error:</p>
  
  <pre><code>#1556 - You can't use locks with log tables.
  </code></pre>
  
  <p>This is the query I ran:</p>
  
  <pre><code>DELETE FROM `general_log` WHERE `event_time` &lt; "2014-01-25 14:05"
  </code></pre>
