body: <p>How do I format a query with multiple order by columns.  The data I'm working with has a date column and a time column and I want to order by both of them.  I know how to do this query in regular SQL but I can't make it work in SoQL.  Here is what I've tried:</p>
  
  <p>This works ('date DESC') but isn't what I'm trying to do: </p>
  
  <pre><code>http://data.sfgov.org/resource/tmnf-yvry.json?$order=date+DESC
  </code></pre>
  
  <p>This fails ('date DESC, time DESC') with a 403 error: </p>
  
  <pre><code>http://data.sfgov.org/resource/tmnf-yvry.json?$order=date+DESC%2Ctime+ASC
  </code></pre>
  
  <p>This fails ("'date DESC, time DESC'") with a 403 error: </p>
  
  <pre><code>http://data.sfgov.org/resource/tmnf-yvry.json?$order=%27date+DESC%2C+time+DESC%27
  </code></pre>
