如何通过JPA/Hibernate中的聚合列进行排序？

Question

通过执行该JPQL：

select o.key, count(o.id), sum(o.errors) from MyEntity o 
group by o.key 

休眠提交的SQL语句：

select 
    myentityn0_.key as col_0_0_, 
    count(myentityn0_.id) as col_1_0_, 
    sum(myentityn0_.errors) as col_2_0_ 
from 
    MYENTITY myentityn0_ 
group by 
    myentityn0_.key 

但我怎么可以用“按订单”，在这种情况下不使用Hibernate的创建列名？如果我在JPQL中使用as，则SQL不会更改。

Answer 1

名称计算在order by：

select 
    o.key, 
    count(o.id), 
    sum(o.errors) 
from MyEntity o 
group by o.key 
order by sum(o.errors)
