Permission to access the subset of data in a view must be explicitly granted or revoked, regardless of the permissions in force on the view’s underlying tables. Data in an underlying table that is not included in the view is hidden from users who are authorized to access the view but not the underlying table.
For example, you may not want some users to access the columns that have to do with money and sales in the titles table. You can create a view of the titles table that omits those columns, and then give all users permission on the view, and give only the Sales Department permission on the table. For example:
revoke all on titles to public grant all on bookview to public grant all on titles to sales
For information about how to grant or revoke permissions, see the System Administration Guide.
