Comentários

Depois de remover a assinatura no Assinante, você deve chamar RemovePullSubscription ou RemovePullSubscription remover o registro de assinatura no Publicador.

O Remove método só pode ser chamado por membros da sysadmin função de servidor fixa no Publicador ou por membros da db_owner função de banco de dados fixa no banco de dados de assinatura.

Chamar Remove é equivalente à execução de sp_droppullsubscription (Transact-SQL) ou sp_dropmergepullsubscription (Transact-SQL).
