PullSubscription.PublicationDBName Property


Gets or sets the name of the publication database.

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

public string PublicationDBName { get; set; }

Property Value

Type: System.String

A String value that specifies the name of the database where the publication is defined.

PublicationDBName is a required property and must be set before the subscription is created on the server. Once the subscription registration exists on the server, the PublicationDBName property cannot be changed.

The PublicationDBName property can only be retrieved by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

The PublicationDBName property can only be set by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

Retrieving the PublicationDBName property is equivalent to executing sp_helppullsubscription (Transact-SQL) or sp_helpmergepullsubscription (Transact-SQL).

Setting the PublicationDBName property is equivalent to executing sp_addpullsubscription (Transact-SQL) or sp_addmergepullsubscription (Transact-SQL).

// 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;

	// Connect to the Publisher and Subscriber.

	// Ensure that the publication exists and that 
	// it supports pull subscriptions.
	publication = new TransPublication();
	publication.Name = publicationName;
	publication.DatabaseName = publicationDbName;
	publication.ConnectionContext = publisherConn;

	if (publication.IsExistingObject)
		if ((publication.Attributes & PublicationAttributes.AllowPull) == 0)
			publication.Attributes |= PublicationAttributes.AllowPull;

		// Define the pull subscription.
		subscription = new TransPullSubscription();
		subscription.ConnectionContext = subscriberConn;
		subscription.PublisherName = publisherName;
		subscription.PublicationName = publicationName;
		subscription.PublicationDBName = publicationDbName;
		subscription.DatabaseName = subscriptionDbName;

		// Specify the Windows login credentials for the Distribution Agent job.
		subscription.SynchronizationAgentProcessSecurity.Login = winLogin;
		subscription.SynchronizationAgentProcessSecurity.Password = winPassword;

		// Make sure that the agent job for the subscription is created.
		subscription.CreateSyncAgentByDefault = true;

                 // By default, subscriptions to transactional publications are synchronized 
                 // continuously, but in this case we only want to synchronize on demand.
                 subscription.AgentSchedule.FrequencyType = ScheduleFrequencyType.OnDemand;

                 // Create the pull subscription at the Subscriber.

		Boolean registered = false;

		// Verify that the subscription is not already registered.
		foreach (TransSubscription existing
			in publication.EnumSubscriptions())
			if (existing.SubscriberName == subscriberName
				&& existing.SubscriptionDBName == subscriptionDbName)
				registered = true;
		if (!registered)
			// Register the subscription with the Publisher.
				subscriberName, subscriptionDbName,
		// Do something here if the publication does not exist.
		throw new ApplicationException(String.Format(
			"The publication '{0}' does not exist on {1}.",
			publicationName, publisherName));
catch (Exception ex)
	// Implement the appropriate error handling here.
	throw new ApplicationException(String.Format(
		"The subscription to {0} could not be created.", publicationName), ex);
