title: MYSQL Order By Sum of Columns
body: <p>Any idea on how to order the results of a MYSQL query by the sum of two columns rather than by a single column?</p>
  
  <pre><code>Select * FROM table ORDER BY (col1+col2) desc
  </code></pre>
  
  <p>I know that won't work., but I hope it conveys what I want to do fairly well.</p>
  
  <p>Thanks!</p>
