주의

Creating a pull subscription using SQL Distributed Management Objects (SQL-DMO) is a two-step process. The application must define the subscription at the Subscriber, and then separately enable the subscription at the Publisher and Distributor.

To create a pull subscription to a transactional or snapshot replication publication

  1. Establish SQLServer object connection to the Subscriber.

  2. Create and populate a TransPullSubscription object.

  3. Add the TransPullSubscription object to the TransPullSubscriptions collection of the appropriate ReplicationDatabase object.

  4. Establish SQLServer object connection to the Publisher.

  5. Use the EnableTransSubscription method of the appropriate ReplicationDatabase object indicating the subscription created in Step 3.

For more information about creating pull subscriptions to transactional and snapshot replication publications using SQL-DMO, see TransPullSubscription Object.
