count行

Question

我有這樣的事情

With q as (some valid query), 
    r as (some other valid query) 

我希望得到的結果是在q和r

的行數，所以我需要做的select(*) from q和select(*) from r

我如何在t-sql中做到這一點？

Answer 1

如果你想要把它作爲列試試這個

With q as (some valid query), 
    r as (some other valid query) 
select COUNT(*) as total from q 
UNION ALL 
select COUNT(*) as total from r 

結果

total 
20054 
2548 

，那麼你就可以非常相似的建議是什麼@gbejic：

With q as (some valid query), 
    r as (some other valid query) 
select (SELECT COUNT(*) from q) as q, (SELECT COUNT(*) from r) as r 

Answer 2

SELECT 
(select COUNT(*) from q) + (select COUNT(*) from r)
