title: pulling data out of mysql creating array with array structure
body: <p>I have a MySql database with three columns: skp, date and usr.  For each skp and date pair there are several usr(s).  Is there a query that will pull the data out with the following array structure:</p>
  
  <pre><code>array[i]['skp']
  array[i]['date']
  array[i]['usr'][j]
  </code></pre>
  
  <p>I'm wondering if somehow using a group by would work?</p>
