Примечание. Приведенный ниже скрипт фактически не устанавливает разрешения для чего-либо, он просто создает скрипт, который можно скопировать и вставить в новый запрос, который затем можно отредактировать перед выполнением.
Нижеприведенный скрипт поможет вам скопировать / клонировать разрешения одного пользователя другому:
--- To copy permissions of one user/role to another user/role.
USE database_name -- Use the database from which you want to extract the permissions

Вот очень хороший сценарий Павла Павловского для выполнения этой работы: http://www.pawlowski.cz/2011/03/cloning-user-rights-database/
Основное преимущество:
Я НЕ автор этого сценария. Сценарий вставлен по этой ссылке в блоге Павла Павловского, см. Ссылку для получения дополнительной информации о том, как использовать сценарий.

Примечание: наконец вы получаете сценарий для всех пользователей и их роли почти готовы. но это не создаст сценарий для предоставления разрешения « Выполнить» для хранимых процедур, даже если для параметра «Разрешения на уровне объекта» выбрано значение «истина».
Основываясь на потрясающем ответе @ Kin-shah, я написал скрипт, который может копировать разрешения всех баз данных в одном экземпляре сервера sql. Он намного хуже читается, но может пригодиться, если у вас много пользователей и много баз данных:
