Comment script toutes les autorisations sur un schéma

SQL Management Studio permet de créer des scripts pour tous les objets db, mais je n'ai jusqu'à présent pas trouvé de moyen de scripter correctement un schéma ou un utilisateur. Les autorisations d'un utilisateur sur un schéma ne sont pas incluses dans le script créé. Ai-je fait quelque chose de mal ou MSFT est-elle un peu bâclée?

Votre ami sys.database_permissionsdoit vérifier / écrire les autorisations.

Vous trouverez ci-dessous le script que j'utilise lors d'une actualisation de PROD sur un serveur DEV ou UAT. Je vais créer un script avant de donner toutes les autorisations et après la restauration, je vais simplement exécuter le script.

Vous devrez créer des scripts d'autorisations en deux étapes, rôles et objets. Comme Kin fait allusion à, vous pouvez utiliser sys.database_permissionspour les objets, mais vous voudrez utiliser sys.database_principalset sys.database_role_memberspour l'appartenance au rôle. Le SQL suivant ne fonctionnera que pour SQL 2012 (les versions précédentes doivent utiliser sp_addrolememberpour les rôles) et doit être exécuté dans le contexte de la base de données pour laquelle vous créez des autorisations de script. Filtrez un utilisateur spécifique si nécessaire.

--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')

Pointe du chapeau à cette réponse pour le deuxième script.
