The SHOW privilege enables you to have access to database object definitions and create text without having access to the data contained by the objects on which the privilege is granted. For example, SHOW permits a user to execute HELP and SHOW requests against an object while at the same time not being able to SELECT from it. Any SQL statement that requires any privilege (such as the HELP and SHOW statements) to be executed can be granted the SHOW privilege.
SHOW is an explicit privilege. Vantage does not grant the creator of an object this privilege automatically on the created user, database, or database object; SHOW must be granted explicitly. You must have the SHOW privilege WITH GRANT OPTION to be able to grant this privilege explicitly to other users and databases.
User DBC automatically has the SHOW privilege and can grant it on dictionary tables to other users and databases.
