If you have implemented Secure Zones, zone users can see the information for objects in their zone in DBC views, but they cannot see the information for any objects outside their zone. If a non-zone user needs to see information for all the zones, you can grant ZONE OVERRIDE privilege. Users with ZONE OVERRIDE privilege can see information from all zones. You can also grant SELECT privilege on a specific view, but users with SELECT privileges on a view obtain different result sets, depending on their zone membership or non-zone status.
