title: Find rows where one field is greater than another one
body: <p>My SQL is a bit rusty. I'm not been able to find a way to retrieve rows where one value is greater than the other one. For example, I have the following row:</p>
  
  <pre><code>{
      ROWID       1,
      CreatedAt   2013-08-03 10:10:23:344,
      UpdatedAt   2013-08-03 11:10:23:344,
  }
  </code></pre>
  
  <p>I would like to perform the query 'select all rows where 'UpdatedAt' is greater than 'CreatedAt' and match rows such the one above. Any ideas?</p>
  
  <p>Thanks for the help!</p>
