Cómo eliminar una suscripción de inserción (programación con RMO)

Las suscripciones de inserción se pueden eliminar mediante programación con los objetos de administración de replicación (RMO). Las clases RMO que se usan para eliminar una suscripción de inserción dependen del tipo de publicación a la se suscribe dicha suscripción.

Para eliminar una suscripción de inserción a una publicación transaccional o de instantáneas

1. Cree una conexión al suscriptor mediante la clase ServerConnection.

2. Cree una instancia de la clase TransSubscription.

3. Establezca las propiedades PublicationName, SubscriptionDBName, SubscriberName y DatabaseName.

4. Establezca la conexión ServerConnection del paso 1 para la propiedad ConnectionContext.

5. Compruebe la propiedad IsExistingObject para asegurarse de que la suscripción existe. Si el valor de esta propiedad es false, significa que las propiedades de suscripción del paso 2 se definieron incorrectamente, o bien que la suscripción no existe.

6. Llame al método Remove.

Para eliminar una suscripción de inserción a una publicación de mezcla

1. Cree una conexión al suscriptor mediante la clase ServerConnection.

2. Cree una instancia de la clase MergeSubscription.

3. Establezca las propiedades PublicationName, SubscriptionDBName, SubscriberName y DatabaseName.

4. Establezca la conexión ServerConnection del paso 1 para la propiedad ConnectionContext.

5. Compruebe la propiedad IsExistingObject para asegurarse de que la suscripción existe. Si el valor de esta propiedad es false, significa que las propiedades de suscripción del paso 2 se definieron incorrectamente, o bien que la suscripción no existe.

6. Llame al método Remove.

Ejemplo
