This topic describes how to delete a pull subscription in SQL Server 2012 by using SQL Server Management Studio, Transact-SQL, or Replication Management Objects (RMO).

In This Topic

To delete a pull subscription, using:

SQL Server Management Studio

Transact-SQL

Replication Management Objects (RMO)

Using SQL Server Management Studio

Delete a pull subscription at the Publisher (from the Local Publications folder in SQL Server Management Studio) or the Subscriber (from the Local Subscriptions folder). Deleting a subscription does not remove objects or data from the subscription; they must be removed manually.

To delete a pull subscription at the Publisher

Connect to the Publisher in SQL Server Management Studio, and then expand the server node.
Expand the Replication folder, and then expand the Local Publications folder.
Expand the publication associated with the subscription you want to delete.
Right-click the subscription, and then click Delete.
In the confirmation dialog box, select whether to connect to the Subscriber to delete subscription information. If you clear the Connect to Subscriber check box, you should connect to the Subscriber later to delete the information.

To delete a pull subscription at the Subscriber

Connect to the Subscriber in SQL Server Management Studio, and then expand the server node.
Expand the Replication folder, and then expand the Local Subscriptions folder.
Right-click the subscription you want to delete, and then click Delete.
In the confirmation dialog box, select whether to connect to the Publisher to delete subscription information. If you clear the Connect to Publisher check box, you should connect to the Publisher later to delete the information.

Using Transact-SQL

Pull subscriptions can be deleted programmatically using replication stored procedures. The stored procedures used will depend on the type of publication to which the subscription belongs.

To delete a pull subscription to a snapshot or transactional publication

At the Subscriber on the subscription database, execute Subscribing to Publications. Specify @publication, @publisher, and @publisher_db.
At the Publisher on the publication database, execute sp_dropsubscription. Specify @publication and @subscriber. Specify a value of all for @article. (Optional) If the Distributor cannot be accessed, specify a value of 1 for @ignore_distributor to delete the subscription without removing related objects at the Distributor.

To delete a pull subscription to a merge publication

At the Subscriber on the subscription database, execute sp_dropmergepullsubscription. Specify @publication, @publisher, and @publisher_db.
At the Publisher on the publication database, execute sp_dropmergesubscription. Specify @publication, @subscriber, and @subscriber_db. Specify a value of pull for @subscription_type. (Optional) If the Distributor cannot be accessed, specify a value of 1 for @ignore_distributor to delete the subscription without removing related objects at the Distributor.

Examples (Transact-SQL)

The following example deletes a pull subscription to a transactional publication. The first batch is executed at the Subscriber and the second is executed at the Publisher.

-- This script uses sqlcmd scripting variables. They are in the form
-- $(MyVariable). For information about how to use scripting variables  
-- on the command line and in SQL Server Management Studio, see the 
-- "Executing Replication Scripts" section in the topic
-- "Programming Replication Using System Stored Procedures".

-- This is the batch executed at the Subscriber to drop 
-- a pull subscription to a transactional publication.
DECLARE @publication AS sysname;
DECLARE @publisher AS sysname;
DECLARE @publicationDB     AS sysname;

SET @publisher = $(PubServer);
SET @publicationDB = N'AdventureWorks2012';

  @publisher_db = @publicationDB, 
  @publication = @publication;

DECLARE @publication AS sysname;

SET @subscriber = $(SubServer);

USE [AdventureWorks2012]

  @article = N'all',
  @subscriber = @subscriber;
GO

Using Replication Management Objects (RMO)

You can delete pull subscriptions programmatically by using Replication Management Objects (RMO). The RMO classes that you use to delete a pull subscription depend on the type of publication to which the pull subscription is subscribed.

To delete a pull subscription to a snapshot or transactional publication

Create connections to both the Subscriber and Publisher by using the ServerConnection Class.
Create an instance of the TransPullSubscription class, and set the PublicationName, DatabaseName, PublisherName, and PublicationDBName properties. Use the Subscriber connection from step 1 to set the ConnectionContext property.
Check the IsExistingObject property to verify that the subscription exists. If the value of this property is false, either the subscription properties in step 2 were defined incorrectly or the subscription does not exist.
Call the Remove method.
Create an instance of the TransPublication class by using the Publisher connection from step 1. Specify Name, DatabaseName and ConnectionContext.
Call the LoadProperties method. If this method returns false, either the properties specified in step 5 are incorrect or the publication does not exist on the server.
Call the RemovePullSubscription method. Specify the name of the Subscriber and the subscription database for the subscriber and subscriberDB parameters.

To delete a pull subscription to a merge publication

Create connections to both the Subscriber and Publisher by using the ServerConnection Class.
Create an instance of the MergePullSubscription class, and set the PublicationName, DatabaseName, PublisherName, and PublicationDBName properties. Use the connection from step 1 to set the ConnectionContext property.
Check the IsExistingObject property to verify that the subscription exists. If the value of this property is false, either the subscription properties in step 2 were defined incorrectly or the subscription does not exist.
Call the Remove method.
Create an instance of the MergePublication class by using the Publisher connection from step 1. Specify Name, DatabaseName and ConnectionContext.
Call the LoadProperties method. If this method returns false, either the properties specified in step 5 are incorrect or the publication does not exist on the server.
Call the RemovePullSubscription method. Specify the name of the Subscriber and the subscription database for the subscriber and subscriberDB parameters.

Examples (RMO)

This example deletes a pull subscription to a transactional publication and removes the subscription registration at the Publisher.

            string publisherName = publisherInstance;

            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;
