We want to restrict a user to read/write only his objects and not anything else. we tried to restrict a user with security realm , FGA (there seems to be no SELECT TRIGGER) but seems to be not possible.. the requirement is we want to prevent user from reading all_* view for example all_views. Can someone please suggest is there anyway to do this. . just not all_views but also sys.all_views (with prefix or without prefix -sys). thanks.
