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.

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

Specifies a schema, by default public. If schema is any schema other than public, you must supply the schema name. For example:

myschema.thisDbObject

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:
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;
