按计数计数的SQL组

Question

这是我的剧本

SELECT COUNT( [Id]) as [Count Of Register],
Tag as [Tag]
FROM [Members]
Group By Tag 
Order By [Count Of Register] Desc;

返回表是这样的:

Count   Tag

550 ----1
550 ----2
545 ----3
545 ----4
545 ----5

所以,这次我需要Count of Tag,Group by这个新的Count字段.

一些返回值如:

2 ---550
3 ---545

有没有办法不使用新表或模板表或任何存储表只是通过查询？

Answer 1

SELECT [Count Of Register], COUNT(1) [Grouped Count]
FROM
(
    SELECT COUNT( [Id]) as [Count Of Register],
           Tag as [Tag]
    FROM [Members]
    Group By Tag 

) MyTable
GROUP BY [Count Of Register]
