title: Delete old records
body: <p>I have a column in my sqlite table which is string and has the following format</p>
  
  <blockquote>
    <p>2011-09-06 18:34:55.863414</p>
  </blockquote>
  
  <p>You can see that it identifies date and time. I'd like to construct a query that will
  delete all records that are older than certain date and time.
  Is this possible?</p>
