将sql视图查询转换为hql

Question

我是Java的新手，所以请尽可能帮忙。 我需要填充Jtable，我正在使用这段代码：

SELECT r.id AS roomID, r.type, r.no_of_rooms, r.no_of_rooms - 
  COALESCE(t.bookedRooms,0) AS available_rooms FROM room AS r  LEFT JOIN (     
  SELECT room_id, SUM(total_rooms) AS bookedRooms   FROM bookings   WHERE 
  `start` < '2017-02-10' AND `ends` > '2017-02-09'   GROUP BY room_id ) AS t 
  ON r.id = t.room_id WHERE r.no_of_rooms - COALESCE(t.bookedRooms,0) > 0

它就像这样。

但是如何使用Hibernate以及如何进行映射呢？ 提前谢谢！
