REVOKE (library)

Revokes library privileges from users and roles.

Syntax

REVOKE [ GRANT OPTION FOR ] { USAGE | ALL [ PRIVILEGES ] }
   ON LIBRARY [[database.]schema.]library[,...]
   FROM grantee[,...]
   [ CASCADE ]

Parameters

GRANT OPTION FOR

Revokes the grant option for the specified privileges. Current privileges for grantees remain unaffected. If you omit this clause, Vertica revokes both the grant option and current privileges.

USAGE

Revokes access to the specified libraries.

Important

Privileges on functions in these libraries must be separately revoked.

ALL [PRIVILEGES]

Revokes all library privileges that also belong to the revoker. Users cannot revoke privileges that they themselves lack. The optional keyword PRIVILEGES conforms with the SQL standard.

[database.]schema

Database and schema. The default schema is public. If you specify a database, it must be the current database.

library

The target library.

grantee

Specifies whose privileges are revoked, one of the following:

• User name

• Role

• PUBLIC: The default role of all users

CASCADE

If the target grantees have a grant option to extend the specified privileges to other users, CASCADE specifies to search for these users and revoke the privileges from them also.

Examples

These commands show how to create a new library, and then grant and revoke user Fred's USAGE privilege on that library.

=> CREATE LIBRARY MyFunctions AS 'home/dbadmin/my_functions.so';
=> GRANT USAGE ON LIBRARY MyFunctions TO Fred;
=> REVOKE USAGE ON LIBRARY MyFunctions FROM Fred;
