如何通过蜂巢中每个组的计数desc订购？

Question

这是HQL：

select A, B, count(*) as cnt from test_table group by A, B order by cnt desc;

示例输出如下：

a1 | b1 | 5
a2 | b1 | 3
a1 | b2 | 2
a2 | b2 | 1

但我想要的是在每组A中执行order by，并且预期输出如下：

a1 | b1 | 5
a1 | b2 | 2
a2 | b1 | 3
a2 | b2 | 1

任何人都可以让我知道如何在一个 HQL中解决此问题？非常感谢！

Answer 1

select A, B, count(*) as cnt 
from test_table 
group by A, B 
order by A, cnt desc;

Answer 2

尝试此查询：

如果您只想订购A，那么：

select A, B, count(*) as cnt from test_table group by A, B order by A asc;

如果您想订购A和B，那么：

select A, B, count(*) as cnt from test_table group by A, B order by A asc,B asc;

希望这有帮助。

Answer 3

select A, B, count(*) as cnt from test_table group by A, B order by A asc, B asc, cnt desc;
