Commenti

Il RemovePullSubscription 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 dall'utente che ha creato la sottoscrizione da rimuovere.

La chiamata RemovePullSubscription equivale all'esecuzione di sp_dropsubscription.
