O SQL Management Studio permite criar scripts para todos os objetos de banco de dados, no entanto, até agora, não consegui encontrar uma maneira de criar um script ou esquema corretamente. As permissões de um usuário em um esquema não estão incluídas no script criado. Cometi algo errado ou a MSFT é um pouco desleixada?
Respostas:
Seu amigo sys.database_permissionsdeve verificar / criar permissões de permissão.
Abaixo está o script que estou usando ao fazer uma atualização do PROD no servidor DEV ou UAT. Escreverei antes todas as permissões e depois da restauração executarei o script.

Você precisará criar permissões de script em duas etapas, funções e objetos. Como o Kin faz alusão, você pode usar sys.database_permissionspara os objetos, mas desejará usar sys.database_principalse sys.database_role_memberspara a associação de função. O SQL a seguir funcionará apenas para o SQL 2012 (versões anteriores devem ser usadas sp_addrolememberpara funções) e deve ser executado no contexto do banco de dados para o qual você está executando permissões de script. Filtre um usuário específico conforme necessário.
--Add to roles
SELECT 'ALTER ROLE ' + quotename(dpr.name,'[') + ' ADD MEMBER ' + quotename(dpu.name,'[')
FROM sys.database_principals dpr
JOIN sys.database_role_members drm on (dpr.principal_id = drm.role_principal_id)
JOIN sys.database_principals dpu on (drm.member_principal_id = dpu.principal_id)
WHERE dpu.principal_id > 4
--Grant explicit permissions
SELECT 'GRANT ' + dp.permission_name collate latin1_general_cs_as
+ ' ON ' + s.name + '.' + o.name + ' TO ' + dpr.name
FROM sys.database_permissions AS dp
INNER JOIN sys.objects AS o ON dp.major_id=o.object_id
INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id
INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
WHERE dpr.name NOT IN ('public','guest')
Dica para esta resposta para o segundo script.
