Notes

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

To set Login object properties, users must have ALTER ANY LOGIN permissions on the server or be a member of the sysadmin fixed server role.

To create or drop a login, users must have ALTER ANY LOGIN permissions on the server or be a member of the sysadmin fixed server role.

To grant, deny, or revoke permission on the login to other users, users must have CONTROL permissions on the logon or be a member of the sysadmin or securityadmin fixed server roles.

To set the password on a login without providing an old password, users must be a member of the sysadmin fixed server role.

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.
