SQL Management Studio permite crear scripts para todos los objetos db, sin embargo, hasta ahora no pude encontrar una manera de escribir correctamente un esquema o usuario. Los permisos de un usuario en un esquema no se incluyen en el script que se crea. ¿Hice algo mal o MSFT es un poco descuidada?
Respuestas:
Tu amigo sys.database_permissionsdebe verificar / escribir permisos.
A continuación se muestra el script que estoy usando al actualizar PROD en el servidor DEV o UAT. Escribiré de antemano todos los permisos y después de la restauración simplemente ejecutaré el script.

DEALLOCATE tmp Deberá crear permisos de script en dos pasos, roles y objetos. Como Kin alude, puede usarlo sys.database_permissionspara los objetos, pero querrá usarlo sys.database_principalsy sys.database_role_memberspara la membresía del rol. El siguiente SQL funcionará solo para SQL 2012 (las versiones anteriores deberían usarse sp_addrolememberpara los roles) y deberían ejecutarse en el contexto de la base de datos para la que está otorgando permisos de secuencias de comandos. Filtra en un usuario específico según sea necesario.
