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

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

To delete a push subscription to a snapshot or transactional publication

  1. 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.

  2. At the Subscriber on the subscription database, execute sp_subscription_cleanup (Transact-SQL) to remove replication metadata in the subscription database.

To delete a push subscription to a merge publication

  1. At the Publisher, execute sp_dropmergesubscription (Transact-SQL), specifying @publication, @subscriber and @subscriber_db. (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.

  2. At the Subscriber on the subscription database, execute sp_mergesubscription_cleanup (Transact-SQL). Specify @publisher, @publisher_db, and @publication. This removes merge metadata from the subscription database.

Example

This example deletes a push subscription to a transactional publication.

-- 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
