need to restrict user access to certain columns in a table
I am using Oracle 10.2.0.4 Standard Edition on win 2008 srv.
I would like to hide some important columns from few tables. I have columns with data related to passwords,salary,credit card info. As i am using standard edition, i cannot use Virtual Database column masking. I can restrict users from insertion,deletion and update on column data but i cannot restrict them from SELECT.
Since i have used these important columns and tables in many of my reports, i dont want to change existing setup of reports.
Please specify few methods by which i can achieve this.
