从 Hibernate Group By 获取最大计数

Question

如何使用条件和投影在休眠中实现以下代码：

select CUSTOMER_NO,count(*) as max_count
from table
group by CUSTOMER_NO
having count(*) in 
(
select 
max(count) 
from 
(
select count(*) as count,CUSTOMER_NO
from table
group by CUSTOMER_NO
) t1
)

Answer 1

查询可以更改为：select CUSTOMER_NO, count(*) as count from temp.t group by CUSTOMER_NO order by count desc limit 1;

同样的标准是：

    criteria.setProjection(Projections.projectionList().add(Projections.groupProperty("CUSTOMER_NO")).add(Projections.rowCount(), "count"));
    criteria.addOrder(Order.desc("count"));
    criteria.setMaxResults(1);
    return criteria.list();

从 Hibernate Group By 获取最大计数
