1个订单800,000个客户800,000个订单 2个订单100,000个客户20万个订单 3个订单30,000个客户90,000个订单等

Answer 1

这将做你想要的，除了它不会总和超过5 - 它会显示尽可能多的故障（所以如果客户订购了50个订单，那么将有一行：

with d1 as 
(select COUNT(*) as [Number of Orders], row_number() 
    over (order by custid ) as [How Many Orders] 
from t2 group by custid)
     select * from d1

Answer 2

根据您的评论，这是您需要的。我删除了＆＃34; SourceId = 80＆＃34;因为我不知道这种情况的目的。

SELECT  NbOrdersPerCustomer.NBOrders,
        COUNT(NbOrdersPerCustomer.CustomerId)
FROM (  SELECT  CustomerId = o.BilltoPersonId,
                NBOrders = COUNT(o.OrigOrderid)
        FROM indo.dbo.Orders o
        WHERE o.isCancelled = 0 
        AND o.isTransacted = 1 
        AND o.DateOrdered >= '4/1/14' 
        GROUP BY o.BilltoPersonId) AS NbOrdersPerCustomer
GROUP BY NbOrdersPerCustomer.NBOrders
