A Name propriedade só pode ser recuperada por membros da sysadmin função de servidor fixa no Assinante ou por membros da função de banco de db_owner dados fixa no banco de dados de assinatura.

Recuperar a Name propriedade é equivalente à execução de sp_helppullsubscription (Transact-SQL) ou sp_helpmergepullsubscription (Transact-SQL).
