Comentarios

Debe llamar MakePullSubscriptionWellKnown a en el publicador al crear una suscripción de extracción.

Use EnumSubscriptions para determinar si una suscripción ya está registrada en el publicador. Si el registro existe, MakePullSubscriptionWellKnown genera un error en el servidor.

Los MakePullSubscriptionWellKnown miembros del rol fijo de sysadmin servidor en el publicador solo pueden llamar al método , los miembros del rol fijo de base de db_owner datos en la base de datos de publicación o los usuarios de la lista de acceso a la publicación (PAL).

Llamar MakePullSubscriptionWellKnown a es equivalente a ejecutar sp_addsubscription para una suscripción de extracción.
