用Group后的合计

[tedder]

原来是这样的
select count(a) as aa,b from # group by b
现在要添加一行，aa的合计

[中国风]

select count(a) as aa,count(1) as '合计',b from # group by b

[jacobsan]

select count(aa) from (select count(a) as aa,b from # group by b) t group by aa

[paoluo]

try

select count(a) as aa,b from # group by b with rollup

[paoluo]

Create Table TEST
(b Int,
a DateTime)

Select COUNT(a) As aa, b From TEST Group By b With Rollup
