Syntax

sp_reinitmergesubscription
    [ [ @publication = ] N'publication' ]
    [ , [ @subscriber = ] N'subscriber' ]
    [ , [ @subscriber_db = ] N'subscriber_db' ]
    [ , [ @upload_first = ] N'upload_first' ]
[ ; ]

Arguments

[ @publication = ] N'publication'

The name of the publication. @publication is sysname, with a default of all.

[ @subscriber = ] N'subscriber'

The name of the Subscriber. @subscriber is sysname, with a default of all.

[ @subscriber_db = ] N'subscriber_db'

The name of the Subscriber database. @subscriber_db is sysname, with a default of all.

[ @upload_first = ] N'upload_first'

Specifies whether changes at the Subscriber are uploaded before the subscription is reinitialized. @upload_first is nvarchar(5), with a default of false.

  • If true, changes are uploaded before the subscription is reinitialized.
  • If false, changes aren't uploaded.

Return code values

0 (success) or 1 (failure).

Remarks

sp_reinitmergesubscription is used in merge replication.

sp_reinitmergesubscription can be called from the Publisher to reinitialize merge subscriptions. You should rerun the Snapshot Agent as well.

If you add, drop, or change a parameterized filter, pending changes at the Subscriber can't be uploaded to the Publisher during reinitialization. If you want to upload pending changes, synchronize all subscriptions before changing the filter.

Examples

A. Reinitialize the push subscription and lose pending changes

-- 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".

DECLARE @subscriptionDB AS sysname;
DECLARE @publication AS sysname;
SET @subscriptionDB = N'AdventureWorks2022Replica';
SET @publication = N'AdvWorksSalesOrdersMerge';

USE [AdventureWorks2022Replica]

-- Execute at the Publisher to reinitialize the push subscription. 
-- Pending changes at the Subscrber are lost.
EXEC sp_reinitmergesubscription 
    @subscriber = $(SubServer),
    @subscriber_db = @subscriptionDB,
    @publication = @publication,
    @upload_first = N'false';
GO

-- Start the Merge Agent.

B. Reinitialize the push subscription and upload pending changes

-- 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".

DECLARE @subscriptionDB AS sysname;
DECLARE @publication AS sysname;
SET @subscriptionDB = N'AdventureWorks2022Replica';
SET @publication = N'AdvWorksSalesOrdersMerge';

USE [AdventureWorks2022Replica]

-- Execute at the Publisher to reinitialize the push subscription, 
-- and upload pending changes at the Subscriber. 
EXEC sp_reinitmergesubscription 
    @subscriber = $(SubServer),
    @subscriber_db = @subscriptionDB,
    @publication = @publication,
    @upload_first = N'true';
GO

-- Start the Merge Agent.
