将查询从 MS Access 转换为 SQL Server

Question

我在 SQL 方面的经验有限，但我被要求从 MS Access 转换以下查询。

TRANSFORM SUM(weekpace_crosstab.wgt) AS SumOfwgt
    SELECT 
        Products.[Product Type], SUM(weekpace_crosstab.wgt) AS DeliveryTotal    
    FROM 
        (weekpace_crosstab 
    LEFT JOIN 
        Customer ON weekpace_crosstab.Customer = Customer.Customer)  LEFT JOIN Products ON weekpace_crosstab.Product = Products.[Product Code]
WHERE (((Customer.[Customer Group])="Sainsbury"))
GROUP BY Products.[Product Type]
PIVOT weekpace_crosstab.Date;

这是结果...

通过谷歌和这个论坛上的其他问题，我写了以下声明。但是，我无法使交付总额如上图所示。

SELECT * FROM 
(
SELECT P.[Product Type], wc.Date, sum (wc.wgt) AS DeliveryTotal

FROM weekpace_crosstab AS wc LEFT JOIN Customer AS C ON wc.Customer = C.Customer LEFT JOIN Products as p 

ON wc.Product = P.[Product Code]

WHERE C.[Customer Group]='Co-op'

GROUP BY  p.[Product Type], wc.Date, wc.wgt
) AS s
PIVOT 
(
SUM (DeliveryTotal)
FOR [Date] in ([2017-01-23],[2017-01-24],[2017-01-25],[2017-01-26],[2017-01-27],[2017-01-28],[2017-01-29])
)AS pvt
ORDER BY [Product Type]

这是这个查询的结果...

任何人都可以建议如何添加交付总额列吗？

感谢您的关注。

Answer 1

您需要将 DeliveryTotal 添加为第二列，因为第一列正在被枢轴使用，它将仅显示为枢轴

试试

SELECT * FROM 
(
SELECT P.[Product Type], wc.Date, sum (wc.wgt) AS DeliveryTotal, w.wgt
FROM weekpace_crosstab AS wc LEFT JOIN Customer AS C ON wc.Customer = 
C.Customer LEFT JOIN Products as p 

ON wc.Product = P.[Product Code]
LEFT JOIN (
SELECT SUM(wgt)wgt, Product 
FROM weekpace_crosstab 
WHERE Date IN ('2017-01-23', '2017-01-24', '2017-01-25', '2017-01-26', '2017-01-
27', '2017-01-28', '2017-01-29')
GROUP BY product) w ON w.Product = wc.product

WHERE C.[Customer Group]='Co-op'

GROUP BY  p.[Product Type], wc.Date, w.wgt
) AS s
PIVOT 
(
SUM (DeliveryTotal)
FOR [Date] in ([2017-01-23],[2017-01-24],[2017-01-25],[2017-01-26],[2017-01-
27],[2017-01-28],[2017-01-29])
)AS pvt
ORDER BY [Product Type]
