body: <p>have looked through the forums already but have been unable to solve this problem:
  Commands out of sync; you can't run this command now SQL</p>
  
  <p>My query is:</p>
  
  <pre><code>SELECT Car.*, Building.*, CarType.* 
  FROM Car 
  INNER JOIN Building 
  ON Car.BuildingID=Building.BuildingID 
  INNER JOIN CarType 
  ON Car.CarType=CarType.TypeID 
  WHERE Car.CarID &lt;&gt; (SELECT CarID FROM Requests WHERE Status = 'Accepted')
  </code></pre>
  
  <p>Any help appreciated.
  thank you</p>
