推荐答案

我们不为您做家庭作业.
自己尝试，如果遇到麻烦，请向我们询问.
但是不要指望我们将它交给您！

We do not do your homework for you.
Try it yourself, and if you get stuck, ask us then.
But don''t expect us to hand it to you on a plate!

普通！ :doh:

尝试使用Google ...努力吧！

Common! :doh:

Try Google... make some effort!

请不要问一个愚蠢的问题，以至于您可能会在面试面板中遇到这个问题.

SELECT是DML ，不需要证明它已经定义.

如果您仍然希望以数学方式进行证明，则继续进行下去. :mad:

SELECT =从表中读取数据
和
DML =数据处理语言
因此，您可以说像
DML =读取数据是对数据的一种操作.
因此，请继续进行最后阶段
DML =从表中读取数据

因此(SELECT = DML)被证明.
:-D :-D

Please don''t ask such a silly question that you may''ve got in interview panel.

SELECT is DML, It isn''t need to be proved It''s defined already.

If you want proof in mathamatical way anyway then just go on with this. :mad:

SELECT = It reads data from table
and
DML = Data Manipulation Language
So further you can say like
DML = Reading data is kind of manipulation in data.
So further go on last stage
DML = It reads data from table

Hence ( SELECT = DML ) Prooved.
:-D :-D
