Commenti

Dopo aver rimosso la sottoscrizione nel Sottoscrittore, è necessario chiamare RemovePullSubscription o RemovePullSubscription rimuovere la registrazione della sottoscrizione nel server di pubblicazione.

Il Remove metodo può essere chiamato solo dai membri del ruolo predefinito del sysadmin server nel server di pubblicazione o dai membri del ruolo predefinito del db_owner database nel database di sottoscrizione.

La chiamata Remove equivale all'esecuzione di sp_droppullsubscription (Transact-SQL) o sp_dropmergepullsubscription (Transact-SQL).
