根據列的值從另一個表中選擇多個列

Question

我什至不確定這是否可行，但是我有一個訂單表（在線商店）。 在此表中，送貨地址和帳單地址列是與地址表相對應的ID。

例如

OrderID     ShippingAddressID   BillingAddressID
201800194   21183               21182

然后，地址表將列出地址信息。

AddressID   Address1            City        RegionCode
21182       123 Somewhere Dr    Hometown1   Florida
21183       456 Elsewhere Rd    Hometown2   Florida

我希望結果清單顯示類似以下內容：

OrderID     BillingAddress1     BillingCity BillingRegionCode   ShippingAddress1    ShippingCity    ShippingRegionCode
201800194   123 Somewhere Dr    Hometown1   Florida             456 Elsewhere Rd    Hometown2       Florida

這有可能嗎？

謝謝..

Answer 1

加入地址表兩次。 下面的數據示例。

CREATE TABLE #Orders (OrderID int, ShippingAddressId int, BillingAddressId int)
CREATE TABLE #Address (AddressID int, Address1 varchar(100), City varchar(100), RegionCode varchar(100))

INSERT INTO #Orders (OrderID, ShippingAddressId, BillingAddressId) VALUES
(201800194 , 21183, 21182)

INSERT INTO #Address (AddressID, Address1, City, RegionCode) VALUES
(21182, '123 Somewhere Dr', 'Hometown1', 'Florida'),
(21183, '456 Elsewhere Rd', 'Hometown2', 'Florida')

SELECT
    ORD.OrderID,
    BILL.Address1 AS 'BillingAddress1',
    BILL.City AS 'BillingCity',
    BILL.RegionCode AS 'BillingRegionCode',
    SHIP.Address1 AS 'ShippingAddress1',
    SHIP.City AS 'ShippingCity',
    SHIP.RegionCode AS 'ShippingRegionCode'
FROM 
    #Orders AS ORD
    LEFT OUTER JOIN #Address AS SHIP
        ON ORD.ShippingAddressId = SHIP.AddressID
    LEFT OUTER JOIN #Address AS BILL
        ON ORD.BillingAddressId = BILL.AddressID

DROP TABLE #Orders
DROP TABLE #Address

假設您的表格是訂單，地址。

Select A.OrderID, B1.Address1 As 'BillingAddress1', B1.City As 'BillingCity', B1.RegionCode As 'BillingRegionCode', B2.Address1 As 'ShippingAddress1', B2.City As 'ShippingCity', B2.RegionCode As 'ShippingRegionCode'
FROM Order AS A
Left Join Address  AS B1 On A.BillingAddressID = B1.AddressID
Left Join Address  As B2 On A.ShippingAddressID = B2.AddressID

希望這可以幫助

是的，您可以使用join這樣實現它-

SELECT OrderId, Billing.Address1 As BillingAddress1, Shipping.Address1 AS 
ShippingAddress1, ... other column
FROM dbo.Order
LEFT JOIN dbo.Address AS Billing ON Order.BillingAddressID = Billing.AddressID
LEFT JOIN dbo.Address AS Shipping ON Order.ShippingAddressID = Shipping.AddressID
