body: <p>Is it possible to create Criteria Query without defining a root? Or should I always define at least one root?</p>
  
  <p><strong>Updated</strong>:</p>
  
  <p>I've tried to do this and I've had an <code>IllegalStateException - no criteria query roots were specified</code></p>
  
  <p>But I wonder if there are any chances to make a criteria query without defining a root? </p>
