title: Creating Sub Directory via SQL INSERT using FileTable
body: <p>Previously, <a href="https://stackoverflow.com/q/10483906/175679">I requested how to create a directory within a <code>FileTable</code> without using File I/O APIs</a>. I now want to create a subdirectory to the parent directory I just created. How do assign my parent during insert? It appears that <code>parent_path_locator</code> is a computed column.</p>
  
  <p>This creates my parent...</p>
  
  <pre class="lang-sql prettyprint-override"><code>INSERT INTO FileTable0 (name,is_directory,is_archive) VALUES ('Directory', 1, 0);
  </code></pre>
  
  <p>How do I create a child directory to this parent in my FileTable?</p>
