Removing Members from a User-Defined Role

Remove a user or role as a member of a role. The user or role loses the ability to use any underlying system privileges or roles of a role, along with the ability to administer the role, if granted.

Prerequisites
Requires administrative privilege over the role being managed.
Task
A minimum number of role or global role administrators (as defined by the MIN_ROLE_ADMINS database option) with a login password must exist for each role at all times. When removing a member from a user-extended role, if the member is an administrator of the role and their removal would violate the minimum requirement, the removal fails.
To remove membership in a user-defined role from a grantee, execute one the these statements:
Revoke Type Statement

all administrative rights to the role

to the role only
