SQL将表名添加为字段

Question

I have seen this done before but I can't remember where I saw it. 我以前看过这个，但是我不记得在哪里看过。

What I need to do is have the table name as a field in a query. 我需要做的是将表名作为查询中的字段。

Say I have a table called users, how would I add the table name 'users' as a column. 假设我有一个名为用户的表，该如何将表名“用户”添加为列。

Like: 喜欢：

 SELECT username, password, **table** as mytable FROM users

看起来很明显，但是您是否考虑了以下问题？

SELECT username, password, 'users' as mytable FROM users
