如何添加新列(作为主键列)以查看

Question

可以添加列（PK）以查看。如果是..我们可以吗？

这是我的观点：

CREATE VIEW [dbo].[SalesDetailView]
AS
SELECT
    DATENAME(yyyy, SH.CreatedDateTime) AS Year,
    DATENAME(mm, SH.CreatedDateTime) AS Month, SH.CreatedDateTime AS Date,
    SH.TransactionName AS Type, SH.SalesHeaderID AS No,
    Customer.CustomerName AS Customer,
    CustomerGroup.CustomerGroupName AS Customer_Group, SH.Reference AS Memo,
    Item.ItemName AS Item, SD.LineDescription AS Item_Description,
    Item.ItemType AS Item_Type, Item.UOM,
    ItemGroup.ItemGroupName AS Item_Group,
    CAST (SD.Quantity AS INT) AS Quantity, CAST(SD.Amount AS MONEY) AS Amount,
    SD.Price, SD.Discount, SH.ExchangeRate AS Exchange_Rate,
    Currency.CurrencyDescription AS Currency, SD.ClassID AS Class_ID,
    SD.SalesTaxID AS SalesTax_ID, SalesTaxGroup.SalesTaxGroupName AS Tax_Group,
    Employee.EmployeeName AS Salesperson,
    ShippingMethod.ShippingMethodName AS Shipping_Method,
    PaymentTerm.PaymentTermName AS Payment_Term,
    PaymentMethod.PaymentMethodName AS Payment_Method
FROM
    SalesHeader SH, Customer
LEFT OUTER JOIN 
    SalesDetail SD ON SH.SalesHeaderID = SD.SalesHeaderID
LEFT OUTER JOIN 
    Item ON SD.ItemID = Item.ItemID
LEFT OUTER JOIN 
    ItemGroup ON Item.ItemGroupId = ItemGroup.ItemGroupID
LEFT OUTER JOIN 
    CustomerGroup ON Customer.CustomerGroupId = CustomerGroup.CustomerGroupID
LEFT OUTER JOIN 
    Employee ON Customer.EmployeeID = Employee.EmployeeID
LEFT OUTER JOIN 
    Currency ON Customer.CurrencyID = Currency.CurrencyID
LEFT OUTER JOIN 
    SalesTaxGroup ON Customer.SalesTaxGroupID = SalesTaxGroup.SalesTaxGroupID
LEFT OUTER JOIN 
    PaymentTerm ON Customer.PaymentTermID = PaymentTerm.PaymentTermID
LEFT OUTER JOIN 
    ShippingMethod ON Customer.ShippingMethodID = ShippingMethod.ShippingMethodID
LEFT OUTER JOIN 
    PaymentMethod ON Customer.PaymentMethodID = PaymentMethod.PaymentMethodID
WHERE
    SH.CustomerID = Customer.CustomerID
    AND SH.TransactionName <> 'SalesOrder'
    AND Sh.TransactionName <> 'Quote'

Answer 1

您可以使用row_number添加唯一列，例如：

CREATE VIEW [dbo].[SalesDetailView]
AS
SELECT
    row_number() over (order by SH.CreatedDateTime) as PK,
    DATENAME(yyyy, SH.CreatedDateTime) AS Year,

如果这不是您的意思，请澄清您的问题。一些示例结果总是有帮助的。

Answer 2

当您看到视图的sp_help时，提到的身份列不过是基础表的身份。

如果您已经在基础表中添加了"身份"列，则只需要更改视图并在选择STMT中添加身份列。

否则您需要先将身份添加到表格中，然后编辑视图以在选择STMT中添加列。

ALTER  VIEW [dbo].[SalesDetailView]
AS
SELECT
    DATENAME(yyyy, SH.CreatedDateTime) AS Year,
    DATENAME(mm, SH.CreatedDateTime) AS Month, SH.CreatedDateTime AS Date,
    SH.TransactionName AS Type, SH.SalesHeaderID AS No,
    Customer.CustomerName AS Customer,
    CustomerGroup.CustomerGroupName AS Customer_Group, SH.Reference AS Memo,
    Item.ItemName AS Item, SD.LineDescription AS Item_Description,
    Item.ItemType AS Item_Type, Item.UOM,
    ItemGroup.ItemGroupName AS Item_Group,
    CAST (SD.Quantity AS INT) AS Quantity, CAST(SD.Amount AS MONEY) AS Amount,
    SD.Price, SD.Discount, SH.ExchangeRate AS Exchange_Rate,
    Currency.CurrencyDescription AS Currency, SD.ClassID AS Class_ID,
    SD.SalesTaxID AS SalesTax_ID, SalesTaxGroup.SalesTaxGroupName AS Tax_Group,
    Employee.EmployeeName AS Salesperson,
    ShippingMethod.ShippingMethodName AS Shipping_Method,
    PaymentTerm.PaymentTermName AS Payment_Term,
    PaymentMethod.PaymentMethodName AS Payment_Method,
    [your column] as  PK
FROM
    SalesHeader SH, Customer
LEFT OUTER JOIN 
    SalesDetail SD ON SH.SalesHeaderID = SD.SalesHeaderID
LEFT OUTER JOIN 
    Item ON SD.ItemID = Item.ItemID
LEFT OUTER JOIN 
    ItemGroup ON Item.ItemGroupId = ItemGroup.ItemGroupID
LEFT OUTER JOIN 
    CustomerGroup ON Customer.CustomerGroupId = CustomerGroup.CustomerGroupID
LEFT OUTER JOIN 
    Employee ON Customer.EmployeeID = Employee.EmployeeID
LEFT OUTER JOIN 
    Currency ON Customer.CurrencyID = Currency.CurrencyID
LEFT OUTER JOIN 
    SalesTaxGroup ON Customer.SalesTaxGroupID = SalesTaxGroup.SalesTaxGroupID
LEFT OUTER JOIN 
    PaymentTerm ON Customer.PaymentTermID = PaymentTerm.PaymentTermID
LEFT OUTER JOIN 
    ShippingMethod ON Customer.ShippingMethodID = ShippingMethod.ShippingMethodID
LEFT OUTER JOIN 
    PaymentMethod ON Customer.PaymentMethodID = PaymentMethod.PaymentMethodID
WHERE
    SH.CustomerID = Customer.CustomerID
    AND SH.TransactionName <> 'SalesOrder'
    AND Sh.TransactionName <> 'Quote'
