title: UPDATE update_date in table
body: <p>In my documents table I have a <code>created_date</code> field which takes today's time and date and puts it into a field called created_date which works great - I have an additional field on the row called <code>updated_date</code> which I need to insert or update when I go back and edit the doc - here is my current method of updating the row:</p>
  
  <pre><code>$q = "UPDATE docs SET doc_name='$dn', doc_content='$dc' WHERE doc_id=$id LIMIT 1";
  </code></pre>
  
  <p>I am not sure where the updated_date would live inside of the SQL or if it need to be an insert?</p>
