Question

尝试在sql server 2012中创建视图，但我有此错误消息

Column names in each view or function must be unique. Column name 'Lastname' in view or function 'vFileImportDPERManagers' is specified more than once.

这是我的观点代码：

    GO



CREATE VIEW [dbo].[vFileImportDPERManagers]
    AS
SELECT M.*,
Managers.*

FROM            dbo.vFileImportDPERDebtors M WITH (NOLOCK)
CROSS APPLY 
(
    SELECT
        M1.Man.value('@j11','varchar(20)') as ManagerKey,
        M1.Man.value('@j12','varchar(50)') as Lastname,
        M1.Man.value('@j13','varchar(50)') as Firstname,
        M1.Man.value('@j14','numeric') as ManagerFunctionId


    FROM DebtorXml.nodes('d1/d36/t324/j1') as M1(Man)
) as Managers
GO

Answer 1

在您的情况下，表dbo.vFileImportDPERDebtors将有一个名为＆＃39; Lastname＆＃39;的列。如果您按名称选择所有列（即将*展开为名称），则可以为一个或两个Lastname列SELECT M.Lastname as Lastname1, Managers.Lastname as Lastname2...添加别名。通常认为不使用“SELECT *＆＃39;。

的最佳做法

在sql server中创建视图＆＃34;每个视图或函数中的名称必须是唯一的＆＃34;
