Como fazer script de todas as permissões em um esquema

  • 772

O SQL Management Studio permite criar scripts para todos os objetos db, mas até agora não consegui encontrar uma maneira de criar scripts corretamente em um esquema ou usuário. As permissões de um usuário em um esquema não são incluídas no script que é criado. Eu fiz algo errado ou a MSFT é um pouco desleixada?

    Seu amigo sys.database_permissionsdeve verificar/roteirizar as permissões.

    Abaixo está o script que estou usando ao fazer uma atualização do PROD no servidor DEV ou UAT. Vou fazer o script antes de todas as permissões e após a restauração, apenas executarei o script.

  2. Você precisará de permissões de script em duas etapas, funções e objetos. Como Kin alude, 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 SQL 2012 (versões anteriores devem usar sp_addrolememberpara funções) e deve ser executado no contexto do banco de dados para o qual você está criando 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 de chapéu para esta resposta para o segundo script.
