title: Cosmos DB - Deleting a document
body: <p>How can I delete an individual record from Cosmos DB?</p>
  
  <p>I can select using SQL syntax:</p>
  
  <pre><code>SELECT *
  FROM collection1
  WHERE (collection1._ts &gt; 0)
  </code></pre>
  
  <p>And sure enough all documents (analogous to rows?) are returned</p>
  
  <p>However this doesn't work when I attempt to delete</p>
  
  <pre><code>DELETE
  FROM collection1
  WHERE (collection1._ts &gt; 0)
  </code></pre>
  
  <p>How do I achieve that?</p>
