revokePrivilegesFromRole
(rolename, privileges, writeConcern)¶Removes the specified privileges from the user-defined role on the database where the method runs. The revokePrivilegesFromRole
method has the following syntax:语法如下所示:
The revokePrivilegesFromRole
method takes the following arguments:
rolename |
string | The name of the user-defined role from which to revoke privileges. |
privileges |
array | An array of privileges to remove from the role. See privileges for more information on the format of the privileges. |
writeConcern |
document | writeConcern document takes the same fields as the getLastError command. |
The db.revokePrivilegesFromRole()
method wraps the revokePrivilegesFromRole

If run on a replica set, db.revokePrivilegesFromRole()
is executed using majority

action from the existing privilege.
You must have the revokeRole
action on the database a privilege targets in order to revoke that privilege. If the privilege targets multiple databases or the cluster
resource, you must have the revokeRole
action on the admin
database.
The following operation removes multiple privileges from the associates
role:
