RE: 9iR2, grant select on a column (without using views) using RLSHm, I think you can't use RLS to restrict access to columns of returned rows. You only can control which entire rows are returned (based on values of some columns).

You have to use views or application logic to control read access to specific columns.

list, i'm ikn the process of designing security for a highly sensitive schema for a bank,

plan:
have multiple oracle users, and use roles, and grant minimum required privs, all the user/role/privs management coded in the application (with in turn would create the db role and user etc)

probolem:
i cannot do a "grant select(col1)on tabname to role1", as select grant on a column level is not supported, to workaround this i must

use views and include all the columns granted seleted privs for a user, then give grant select on this view to user.
somehow use RLS ??

TIA -Rahul
