可能重复:
是否有充分的理由对T-SQL关键字使用大写？

简单的问题.我个人发现一串小写字符比一串大写字符更易读.是一些旧的/流行的SQL味道敏感或什么？

以供参考:

select
    this.Column1,
    case when this.Column2 is null then 0 else this.Column2 end
from dbo.SomeTable this
    inner join dbo.AnotherTable another on this.id = another.id
where
    this.Price > 100

与

SELECT
    this.Column1,
    CASE WHEN this.Column2 IS NULL THEN 0 ELSE this.Column2 END
FROM dbo.SomeTable this
    INNER JOIN dbo.AnotherTable another ON this.id = another.id
WHERE
    this.Price > 100

前者对我来说似乎更具可读性,但我更经常地看到后一种方式.
