如何按蜂巢中每个组中的计数顺序排序？

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中做order by，预期的输出是这样的：

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

谁能告诉我如何在一个 HQL 中解决这个问题？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

试试这个查询：

如果你只想要 A 的顺序，那么：

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

如果你想要 A 和 B 的顺序，那么：

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

希望这会有所帮助。

Answer 3

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