Замечания

To get DatabaseRole object properties, users can be a member of the public fixed server role.

To set DatabaseRole object properties, users must have ALTER permission on the database role.

To create a database role, users must have CREATE ROLE permission on the parent database.

To drop a database role, users must have ALTER ANY ROLE permission on the parent database.

To add or remove members from the database role, users must be members of the db_owner or db_security admin fixed database role.

To grant, deny, or revoke permission on the database for other users, users must have CONTROL permission on the database role.
