title: In ObjectBox, using QueryBuilder, can I compare two Properties to each other?
body: <p>I know I can do </p>
  
  <pre><code>myBox.query().less(BasicAchievement_.currentSteps, 5);
  </code></pre>
  
  <p>But I want to be able to do</p>
  
  <pre><code>myBox.query().less(BasicAchievement_.currentSteps, BasicAchievement_.totalSteps)
  </code></pre>
  
  <p>Is this possible? I assume it would be. If not, can I join two 'tables' together (I can only really think in SQL terms, sorry)</p>
  
  <p>I guess I'm asking for the equivalent of</p>
  
  <pre><code>SELECT * FROM myTable WHERE currentSteps &lt; totalSteps;
  </code></pre>
