如果您正在使用聚合，则列需要位于group by或聚合

中

group by没有意义，因为您将拥有多个客户，而客户并没有真正汇总。

我猜你想要这样的东西

  SELECT O.CustomerName, O.CreateDate, sum(TotalCost) as 'SumCost', sum(TotalCount)  as 'SumCount'                             
    FROM   [Order] O
           INNER JOIN Store S
             ON S.StoreID = O.StoreId
           INNER JOIN Customer C2
             ON C2.CustomerID = O.CustId
           INNER JOIN (SELECT SUM(OrderQty)            AS TotalCount,
                              SUM(OrderQty * CaseCost) AS TotalCost,
                              OrderId
                       FROM   OrderItem OI
                       GROUP  BY OrderId) OI
             ON OI.OrderId = O.OrderId
           INNER JOIN AllWeeks
             ON WeekNo = [Week]
                AND YearNo = [Year],
           OrderItem OI1
    GROUP  BY O.CustomerName, O.CreateDate

Group By Clause显示聚合方法错误
