麻烦转换SQL查询到JPQL（的EclipseLink）

Question

嗨，我有以下查询和我的生活，我似乎无法把它翻译成JPQL。工作SQL是：

select * from TB_PRINT_DETAIL y inner join 
(select JOB_ID,max(COPY_NUM) MAX_COPY_NUM from TB_PRINT_DETAIL  group by JOB_ID  ) x
on y.JOB_ID = x.JOB_ID and y.COPY_NUM = x.MAX_COPY_NUM

我在翻译它微弱尝试如下：

select o from PrintDetailEntity o inner join (select o2.jobId, max(o2.copyNumber) as
maxCopyNum from PrintDetailEntity o2 group by o2.jobId ) as x on o.jobId = o2.jobId and
o.copyNum = o2.maxCopyNum where o.printSuppressionReasonEntity is null

在此先感谢任何光线就可以大放异彩！

如果我理解您的查询权（选择具有相同copyNumber中的entites中最大的jobId实体），下面应该工作：

SELECT o 
FROM PrintDetailEntity o 
WHERE o.copyNumber = 
    (SELECT MAX(e.copyNumber) FROM PrintDetailEntity e WHERE o.jobId = e.jobId)
