Sir

i am new to database.I am doing an oracle course on 051.My oracle faculty is saying

Set unused column

option will hide the column for-ever.user can't retrieve it again.
what i believe if a statement is hiding a column there must be some option to regain it.

Is there any option of to make an unused column to reusable again?
