Access Query +您的查詢不包含指定的表達式“ TimeID”作為聚合函數的一部分

Question

嘗試運行查詢時出現以下錯誤

您的查詢未將指定的表達式“ TimeID”作為聚合函數的一部分

INSERT INTO dwSalesFacts ( FactID, TimeID, CustomerID, EmployeeID, LocationID, ProductID, Quantity, UnitPrice, Discount )
SELECT COUNT(FactID), dwTime.TimeID, Orders.[Customer ID], Orders.[Employee ID], dwLocation.LocationID, [Order Details].[Product ID], [Order Details].Quantity, [Order Details].[Unit Price], [Order Details].Discount
FROM Orders, dwTime, dwLocation, [Order Details];

Answer 1

由於您的SELECT語句中有COUNT(FactID) ，因此需要指定GROUP BY如下所示：

GROUP BY dwTime.TimeID, Orders.[Customer ID], 
  Orders.[Employee ID], dwLocation.LocationID, 
  [Order Details].[Product ID], [Order Details].Quantity, 
  [Order Details].[Unit Price], [Order Details].Discount

不知道這是否是您想要的計數分組，但是根據您的選擇，這將是必須的。

如果FactID是一個自動編號字段，那么您甚至不需要指定它。 請嘗試以下操作：

INSERT INTO dwSalesFacts (TimeID, CustomerID, EmployeeID, LocationID, 
    ProductID, Quantity, UnitPrice, Discount)
SELECT t.TimeID, o.[Customer ID], o.[Employee ID], l.LocationID, 
    od.[Product ID], od.Quantity, od.[Unit Price], od.Discount
FROM Orders AS o, dwTime AS t, dwLocation AS l, [Order Details] AS od
