Defines a Teradata Secure Zone. You can also specify an existing database or user as the zone root.
A secure zone is an area which restricts unauthorized outside users from accessing data and objects within the zone.
The zone root is a database or a user on which a zone is created. You create a secure zone and associate a database or a user as the root. Before assigning the database or user as the root of a zone, the database or user should not contain any objects, users, databases, roles, or profiles.
For information on adding guests to a zone, see GRANT ZONE in SQL Data Control Language, B035-1149
For information on assigning a primary Database Administrator to a zone, see the chapter on secure zones in Security Administration, B035-1100
To create a secure zone, you must have the CREATE ZONE privilege.
To define a user as a root, the zone creator must have DROP USER privilege on the user that becomes a root.
To define a database as root, the zone creator must have CREATE USER privilege on the database that becomes a root.
