sql - 列名称的别名中的大写字母不起作用

Question

在下面的 select 语句中firstname和Middlename ALIAS 没有出现。我希望此列标题为大写。

SELECT  dbo.Employee.Title AS SAL,
        dbo.Employee.FirstName AS FIRSTNAME,
        dbo.Employee.MiddleName AS MIDDLENAME
FROM dbo.Employee 

Answer 1

我已经尝试过了，它对我来说很好用。但是，这里建议对您的 SQL 进行更改，这可能会有所帮助。

SELECT Title AS [SAL],
       FirstName AS [FIRSTNAME],
       MiddleName AS [MIDDLENAME]
FROM dbo.Employee 

Answer 2

使用双引号适用于 PostgreSQL。

SELECT Title AS "SAL",
   FirstName AS "FIRSTNAME",
   MiddleName AS "MIDDLENAME"
FROM dbo.Employee
