Question

我正在尝试在hql中进行此查询，因此我不必将查询结果映射到我的java对象中，但在尝试不同的选项后，我仍然无法使其工作。是否可以以任何方式在hql中执行此查询？查询是：

select t.*
from part_movement t 
  join 
    ( select id_block_movement, max(start_date) as somedate 
      from part_movement 
      where id_area_final_destination = 1
   and ((id_area_destination != id_area_final_destination and id_user_receiver is not null) or
(id_area_destination = id_area_final_destination and id_user_receiver is null))
      group by id_block_movement
    ) s 
    on  s.id_block_movement = t.id_block_movement 
    and s.somedate= t.start_date;

先谢谢！

好吧我终于明白了!!它是:(感觉有线回答我自己没有任何其他人的衣服）

Query q2 = s.createQuery(" from PartMovement t "
                + " WHERE t.areaByIdAreaFinalDestination = ? "
                + " AND t.startDate IN (select max(b.startDate) from PartMovement b "
                + " WHERE ((b.areaByIdAreaDestination != b.areaByIdAreaFinalDestination and b.usersByIdUserReceiver is not null) OR "
                + " (b.areaByIdAreaDestination = b.areaByIdAreaFinalDestination and b.usersByIdUserReceiver is null)) "
                                                + "  group by b.idBlockMovement )");

如何使用join和max将sql转换为hql
