Answer 1

這會做你想要它除了在5不會和什麼 - 它會shpw您擊穿儘可能多的有（因此，如果一個客戶做50個訂單將有一排爲：

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

根據您的評論，這裏是你所需要的。 我刪除了「SourceId = 80」，因爲我不知道這種情況的目的。

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
