PullSubscription.Remove Method

Removes the pull subscription.

Namespace:  Microsoft.SqlServer.Replication
Assembly:  Microsoft.SqlServer.Rmo (in Microsoft.SqlServer.Rmo.dll)

public void Remove()

After removing the subscription at the Subscriber, you must call RemovePullSubscription or RemovePullSubscription to remove the subscription registration at the Publisher.

The Remove method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the subscription database.

Calling Remove is equivalent to executing sp_droppullsubscription (Transact-SQL) or sp_dropmergepullsubscription (Transact-SQL).

This example deletes a pull subscription to a transactional publication.

			// Define the Publisher, publication, and databases.
			string publicationName = "AdvWorksProductTran";
			string publisherName = publisherInstance;
			string subscriberName = subscriberInstance;
			string subscriptionDbName = "AdventureWorks2012Replica";
			string publicationDbName = "AdventureWorks2012";

			//Create connections to the Publisher and Subscriber.
			ServerConnection subscriberConn = new ServerConnection(subscriberName);
			ServerConnection publisherConn = new ServerConnection(publisherName);

			// Create the objects that we need.
			TransPublication publication;
			TransPullSubscription subscription;

			try
			{
				// Connect to the Subscriber.
				subscriberConn.Connect();

				// Define the pull subscription.
