我正在尝试使用以下SQL组合表中的2个结果:
select * (
SELECT Datepart(mm,starttime) as Month, COUNT(*) TotalCountSub
from data
where usertype='subscriber'
group by Datepart(mm,starttime)
having count(*) > 1
) a
LEFT JOIN (
SELECT Datepart(mm,starttime) as Month, COUNT(*) TotalCountCust
from data
where usertype='Customer'
group by Datepart(mm,starttime)
having count(*) > 1
) b on a.Month = b.Month
order by Datepart(mm,starttime) ASC
我想在这里实现的是将两个结果合并到一个表中:
表1
Month|TotalCountSub
1 |50
2 |123
3 |14
4 |91
表2
Month|TotalCountCust
1 |80
2 |465
3 |79
4 |84
结果应该是:
Month|TotalCountSub|TotalCountCust
1 |50 |80
2 |123 |465
3 |14 |79
4 |91 |84
答案 0 :(得分:0)
希望这有效:
select a.Month, a.TotalCountSub, b.TotalCountCust from (
SELECT Datepart(mm,starttime) as Month, COUNT(*) TotalCountSub
from data
where usertype='subscriber'
group by Datepart(mm,starttime)
having count(*) > 1
) a
INNER JOIN (
SELECT Datepart(mm,starttime) as Month, COUNT(*) TotalCountCust
from data
where usertype='Customer'
group by Datepart(mm,starttime)
having count(*) > 1
) b
ON a.Month = b.Month
order by a.Month ASC
