Как заскриптовать все логины на SQL Server, их серверные роли + пользователей с правами в базе данных?
SQL Server MVP Алексей Князев попробовал решить эту задачу и его заявка на победу 
тут – Снимок УЗ в SQL Server , в его блоге T-SQL.RU.
За основу взят скрипт от microsoft (http://support.microsoft.com/kb/918992/ru), плюс немного интеллектуального труда и вот цитата T-SQL кодом из его блога:

Сценарий создает в базе данных master две хранимых процедуры — sp_hexadecimal и sp_help_revlogin_with_roles.
Далее вызываем процедуру и получаем скрипт-снимок состояния УЗ на сервере БД:
———————————————
EXEC master..sp_help_revlogin_with_roles
———————————————
Применимо:
SQL Server 2005 и выше
Замечательный на мой взгляд скрипт для решения задачи обслуживания индексов баз данных MS SQL Server® опубликовал Michelle Ufford в своем блоге – Index Defrag Script, v4.0.
