ALIAS中的大写字母列名称不起作用

Question

在以下选择语句名字和中间名中，ALIAS不会出现。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

我试过了，它对我来说很好。但是，这是对SQL的建议更改，这可能有所帮助。

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

Answer 2

在PostgreSQL上使用双引号即可。

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