title: What is a valid dynamodb key-condition-expression for the cli
body: <p>Could somebody please tell me what a valid key condition expression would be. I am trying to run a query on a simple table called MyKeyTable. It has two "columns," namely Id and AnotherNumberThatICareAbout which is of type Long.</p>
  
  <p>I would like to see all the values I put in. So I tried:</p>
  
  <pre><code>aws dynamodb query --select ALL_ATTRIBUTES --table-name MyKeyTable
  --endpoint http://localhost:8000 
  --key-condition-expression "WHAT DO I PUT IN HERE?"
  </code></pre>
  
  <p>What hash do I need to put in? The docs are a bit lame on this imho. Any help appreciated, even if it's just a link to a good doc.</p>
