Answer 1

EmployeeID在您的select语句中出现两次，使用别名或删除其中一列。

SELECT 
     Employees.EmployeeID    <-------
    ,Employees.LastName
    ,Employees.FirstName
    ,Employees.Title
    ,Employees.TitleOfCourtesy
    ,Employees.BirthDate
    ,Employees.HireDate
    ,Employees.Address
    ,Employees.City
    ,Employees.Region
    ,Employees.PostalCode
    ,Employees.Country
    ,Employees.HomePhone
    ,Employees.Extension
    ,Employees.Photo
    ,Employees.Notes
    ,Employees.ReportsTo
    ,Employees.PhotoPath
    ,Orders.OrderID
    ,Orders.CustomerID
    ,Orders.EmployeeID      <-------

例如：

    ,Orders.EmployeeID as OrderEmployeeID

Answer 2

您的临时表列名称将只是列名称。它不会包含您的表名。要回答您的问题，请从select语句中删除重复的列名称或提供别名。

SELECT 
     Employees.EmployeeID // this is enough
    ,Employees.LastName
    ,Employees.FirstName
    ,Employees.Title
    ,Employees.TitleOfCourtesy
    ,Employees.BirthDate
    ,Employees.HireDate
    ,Employees.Address
    ,Employees.City
    ,Employees.Region
    ,Employees.PostalCode
    ,Employees.Country
    ,Employees.HomePhone
    ,Employees.Extension
    ,Employees.Photo
    ,Employees.Notes
    ,Employees.ReportsTo
    ,Employees.PhotoPath
    ,Orders.OrderID
    ,Orders.CustomerID
    // remove this line. Or use alias
    ,Orders.EmployeeID AS [Orders_EmloyeeID]
    // ,Orders.EmployeeID
    ,Orders.OrderDate
    ,Orders.RequiredDate
    ,Orders.ShippedDate
    ,Orders.ShipVia 

Answer 3

更改部分Employees.EmployeeID as ID
