Question

我正在运行此查询并得到下面提到的错误.有人可以帮忙吗？

列名"中间名"包含FOR XML所需的无效XML标识符; ''(0x0020)是第一个出错的角色.

SELECT 
    Username as [LastName],
    '' AS [Middle Name],
    '' AS Birthdate,
    '' AS [SSN],
    0 AS [Wage Amount]
    FROM
    Employee
     FOR XML PATH

Answer 1

XML元素或属性名称中不能包含空格.使用

SELECT Username AS [LastName],
       ''       AS [MiddleName],
       ''       AS Birthdate,
       ''       AS [SSN],
       0        AS [WageAmount]
FROM   Employee
FOR XML PATH
