Commenti

È necessario chiamare MakePullSubscriptionWellKnown nel server di pubblicazione durante la creazione di una sottoscrizione pull.

Usare EnumSubscriptions per determinare se una sottoscrizione è già registrata nel server di pubblicazione. Se la registrazione esiste, MakePullSubscriptionWellKnown genera un errore nel server.

Il MakePullSubscriptionWellKnown metodo può essere chiamato solo dai membri del ruolo predefinito del sysadmin server nel server di pubblicazione, dai membri del ruolo predefinito del db_owner database nel database di pubblicazione o dagli utenti nell'elenco di accesso alla pubblicazione .

La chiamata MakePullSubscriptionWellKnown equivale all'esecuzione di sp_addsubscription per una sottoscrizione pull.
