DROP ROLE
Purpose
Use the DROP ROLE statement to remove a role from the database. When you drop a role, Oracle Database revokes it from all users and roles to whom it has been granted and removes it from the database. User sessions in which the role is already enabled are not affected. However, no new user session can enable the role after it is dropped.

Prerequisites
You must have been granted the role with the ADMIN OPTION or you must have the DROP ANY ROLE system privilege.
