How to: Delete a Pull Subscription (Replication Transact-SQL Programming)

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

  1. At the Subscriber on the subscription database, execute sp_droppullsubscription (Transact-SQL). Specify @publication, @publisher, and @publisher_db.

  2. At the Publisher on the publication database, execute sp_dropsubscription (Transact-SQL). 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

  1. At the Subscriber on the subscription database, execute sp_dropmergepullsubscription (Transact-SQL). Specify @publication, @publisher, and @publisher_db.

  2. At the Publisher on the publication database, execute sp_dropmergesubscription (Transact-SQL). 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.

Example

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 @publication = N'AdvWorksProductTran';
SET @publisher = $(PubServer);
SET @publicationDB = N'AdventureWorks2008R2';

USE [AdventureWorks2008R2Replica]
EXEC sp_droppullsubscription 
  @publisher = @publisher, 
  @publisher_db = @publicationDB, 
  @publication = @publication;
GO

-- 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 batch is executed at the Publisher to remove 
-- a pull or push subscription to a transactional publication.
DECLARE @publication AS sysname;
DECLARE @subscriber AS sysname;
SET @publication = N'AdvWorksProductTran';
SET @subscriber = $(SubServer);

USE [AdventureWorks2008R2;]
EXEC sp_dropsubscription 
  @publication = @publication, 
  @article = N'all',
  @subscriber = @subscriber;
GO

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

-- on the command line and in SQL Server Management Studio, see the

-- This batch is executed at the Subscriber to remove 
-- a merge pull subscription.
DECLARE @publication AS sysname;
DECLARE @publisher AS sysname;
DECLARE @publication_db AS sysname;
SET @publication = N'AdvWorksSalesOrdersMerge';
SET @publisher = $(PubServer);
SET @publication_db = N'AdventureWorks2008R2';

USE [AdventureWorks2008R2Replica]
EXEC sp_dropmergepullsubscription 
  @publisher = @publisher,

USE [AdventureWorks2008R2]
EXEC sp_dropmergesubscription 
  @publication = @publication, 
  @subscriber = @subscriber,
