Comentários

Você deve chamar MakePullSubscriptionWellKnown no Publicador ao criar uma assinatura pull.

Use EnumSubscriptions para determinar se uma assinatura já está registrada no Publicador. Se o registro existir, MakePullSubscriptionWellKnown gerará um erro no servidor.

O MakePullSubscriptionWellKnown método só pode ser chamado por membros da sysadmin função de servidor fixa no Publicador, por membros da função de banco de db_owner dados fixa no banco de dados de publicação ou por usuários na PAL (lista de acesso à publicação).

Chamar MakePullSubscriptionWellKnown é equivalente à execução de sp_addsubscription para uma assinatura pull.
