HQL在集合中的顺序

Question

我有2个实体:汽车和轮子(oneToMany),我想要检索我的汽车,所有车轮和(这是棘手的部分)由wheels.location订购.下面的代码抛出一个异常,消息"非法尝试取消引用收集".

Select c
  from Car
       LEFT JOIN FETCH c.wheels
order by c.wheels.location

知道如何做到这一点,如果在HQL中可以做到这一点？

Answer 1

SELECT DISTINCT c
  FROM Car
       LEFT JOIN FETCH c.wheels AS wheels
ORDER BY wheels.location
