我需要生成hql查询。我的表结构如下所示 A -----一对多------>乙
和我的oracle db query
select a.CONF_NUMBER,to_char(max(b.RECEIVE_DATE), 'YYYY-MM-DD hh24:mi:ss')
from A a, B b
where b.RECEIVE_DATE >= to_date('2012-06-07 13:20:28','YYYY-MM-DD hh24:mi:ss')
group by a.CONF_NUMBER
这里我对如何应用max(b.RECEIVE_DATE)的事实感到困惑 对于子查询如何在HQL中工作而感到困惑
答案 0 :(得分:1)
尝试这样的事情:
DTO :
public interface NumAndDate {
String getNumber();
Date getDate();
}
<强>存储库强>:
public interface ARepository extends JpaRepository<A, Long> {
@Query("select a.confNumber as number, max(b.receiveDate) as date from A a join a.b b where b.receiveDate >= ?1 group by a.confNumber")
List<NumAndDate> getDataByDate(Date date);
}
