将SQL查询转换为JPQL（Eclipselink）的问题

Question

嘿家伙，我有以下查询和我的生活，我似乎无法将其翻译成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 

我的翻译是如下愚蠢的尝试：事先你可以照任何光线

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 

谢谢！

如果我理解您的查询权（选择具有相同jobId中的entites中最大的copyNumber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)
