Campos
Anonymous | 3 | La suscripción de extracción no se registró explícitamente en el publicador utilizando MakePullSubscriptionWellKnown(String, String, SubscriptionSyncType, MergeSubscriberType, Single). Se requieren suscripciones anónimas para crear una suscripción sin registrarla en el publicador. Esto es necesario para casos como la sincronización web, en los que no se puede establecer una conexión SQL Server con el publicador durante la configuración de la suscripción. |
Global | 1 | La suscripción es una suscripción de servidor. Este tipo se utiliza normalmente para los suscriptores que vuelven a publicar los datos a otros suscriptores. |
Local | 2 | La suscripción es una suscripción de cliente. Este tipo de suscripción es adecuado para la mayoría de los suscriptores. |
