Java 如何计算HQL中的子查询？

我需要用HQL（在JPA中使用Hibernate）计算这个子查询

我没有使用Hibernate库，所以我只能用HQL计算。

有人能帮我吗？非常感谢

在回答你的问题之前，也许应该询问更多细节，但我似乎没有足够的观点（或声誉）像其他人那样去做。无论如何，下面是我的想法

假设有XoopsSalesOrder.Id作为主键，XoopsSalesOrder.customerCode是唯一的

select s.customerName, s.customerCode, s.orderDate as last_order_date 
from XoopsSalesOrder s 
where s.Id in (
  select s2.Id from XoopsSalesOrder s2 
  where 
  s2.orderDate = max(s2.orderDate) 
  and s2.orderDate between '2012-7-1' AND '2012-10-1' 
  and s2.orderDate not between '2012-10-1' AND current_date 
  group by s2.customerCode
)

你最终有没有找到一种不绘制完整结果集的方法？

select s.customerName, s.customerCode, s.orderDate as last_order_date 
from XoopsSalesOrder s 
where s.Id in (
  select s2.Id from XoopsSalesOrder s2 
  where 
  s2.orderDate = max(s2.orderDate) 
  and s2.orderDate between '2012-7-1' AND '2012-10-1' 
  and s2.orderDate not between '2012-10-1' AND current_date 
  group by s2.customerCode
)
