Notes

To get User object properties, users can be a member of the public fixed server role.

To set User object properties, uses must have ALTER ANY USER permission on the database or be a member of the db_owner fixed database role.

To change the default schema, users must have ALTER permission on the specified user or be the owner of the user.

To create or drop a user, users must have ALTER ANY USER permission on the fixed server role or be a member of the db_owner fixed database role.

To grant, deny, or revoke permission on the specified user to other users, users must have CONTROL permission on the specified user.

Thread Safety

Tout membre statique public (Partagé dans Microsoft Visual Basic) de ce type est sûr dans le cadre des opérations à plusieurs threads. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.

Exemples

Gestion des utilisateurs, rôles et connexions

Sécurité des threads

Tous les membres publics static (Shared dans Visual Basic) de ce type sont thread-safe. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.
