[ @publication=] 'publication'
Is the name of the publication. publication is sysname, with no default. The publication must already exist.

[ @subscriber =] 'subscriber'
Is the name of the Subscriber. subscriber is sysname, with a default of NULL.

[ @subscriber_db=] 'subscriber_db'
Is the name of the subscription database. subscriber_dbis sysname, with a default of NULL.

[ @subscription_type=] 'subscription_type'
Is the type of subscription. subscription_typeis nvarchar(15), with a default of PUSH. If push, a push subscription is added and the Merge Agent is added at the Distributor. If pull, a pull subscription is added without adding a Merge Agent at the Distributor.

System_CAPS_ICON_note.jpg Note


Anonymous subscriptions do not need to use this stored procedure.

[ @subscriber_type=] 'subscriber_type'
Is the type of Subscriber. subscriber_typeis nvarchar(15), and can be one of the following values.

ValueDescription
local (default)Subscriber known only to the Publisher.
globalSubscriber known to all servers.

In SQL Server 2005 and later versions, local subscriptions are referred to as client subscriptions, and global subscriptions are referred to as server subscriptions

[ @subscription_priority=] subscription_priority
Is a number indicating the priority for the subscription. subscription_priorityis real, with a default of NULL. For local and anonymous subscriptions, the priority is 0.0. For global subscriptions, the priority must be less than 100.0.

[ @sync_type=] 'sync_type'
Is the subscription synchronization type. sync_typeis nvarchar(15), with a default of automatic. Can be automatic or none. If automatic, the schema and initial data for published tables are transferred to the Subscriber first. If none, it is assumed the Subscriber already has the schema and initial data for published tables. System tables and data are always transferred.

System_CAPS_ICON_note.jpg Note


We recommend to not specifying a value of none.

[ @frequency_type=] frequency_type
Is a value indicating when the Merge Agent will run. frequency_type is int, and can be one of the following values.

ValueDescription
1Once
4Daily
8Weekly
10Monthly
20Monthly, relative to the frequency interval
40When SQL Server Agent starts
NULL (default)

[ @frequency_interval=] frequency_interval
The day or days that the Merge Agent runs. frequency_interval is int, and can be one of the following values.

ValueDescription
1Sunday
2Monday
3Tuesday
4Wednesday
5Thursday
6Friday
7Saturday
8Day
9Weekdays
10Weekend days
NULL (default)

[ @frequency_relative_interval=] frequency_relative_interval
Is the scheduled merge occurrence of the frequency interval in each month. frequency_relative_interval is int, and can be one of these values.

ValueDescription
1First
2Second
4Third
8Fourth
16Last
NULL (default)

[ @frequency_recurrence_factor=] frequency_recurrence_factor
Is the recurrence factor used by frequency_type. frequency_recurrence_factoris int, with a default of NULL.

[ @frequency_subday=] frequency_subday
Is the unit for frequency_subday_interval. frequency_subday is int, and can be one of the following values.

ValueDescription
1Once
2Second
4Minute
8Hour
NULL (default)

[ @frequency_subday_interval=] frequency_subday_interval
Is the frequency for frequency_subday to occur between each merge. frequency_subday_interval is int, with a default of NULL.

[ @active_start_time_of_day=] active_start_time_of_day
Is the time of day when the Merge Agent is first scheduled, formatted as HHMMSS. active_start_time_of_day is int, with a default of NULL.

[ @active_end_time_of_day=] active_end_time_of_day
Is the time of day when the Merge Agent stops being scheduled, formatted as HHMMSS. active_end_time_of_day is int, with a default of NULL.

[ @active_start_date=] active_start_date
Is the date when the Merge Agent is first scheduled, formatted as YYYYMMDD. active_start_date is int, with a default of NULL.

[ @active_end_date=] active_end_date

[ @enabled_for_syncmgr=] 'enabled_for_syncmgr'
Specifies if the subscription can be synchronized through Microsoft Windows Synchronization Manager. enabled_for_syncmgr is nvarchar(5), with a default of FALSE. If false, the subscription is not registered with Synchronization Manager. If true, the subscription is registered with Synchronization Manager and can be synchronized without starting Microsoft SQL Server Management Studio.

[ @offloadagent= ] remote_agent_activation
Specifies that the agent can be activated remotely. remote_agent_activation is bit with a default of 0.

System_CAPS_ICON_note.jpg Note


This parameter has been deprecated and is only maintained for backward compatibility of scripts.

[ @offloadserver= ] 'remote_agent_server_name'
Specifies the network name of server to be used for remote agent activation. remote_agent_server_nameis sysname, with a default of NULL.

Overrides the value returned by HOST_NAME when this function is used in the WHERE clause of a parameterized filter. Hostname is sysname, with a default of NULL.

System_CAPS_ICON_important.jpg Important


For performance reasons, we recommend that you not apply functions to column names in parameterized row filter clauses, such as LEFT([MyColumn]) = SUSER_SNAME(). If you use HOST_NAME in a filter clause and override the HOST_NAME value, it might be necessary to convert data types using CONVERT. For more information about best practices for this case, see the section "Overriding the HOST_NAME() Value" in the topic Parameterized Row Filters.

sp_addmergesubscription is used in merge replication.

When sp_addmergesubscription is executed by a member of the sysadmin fixed server role to create a push subscription, the Merge Agent job is implicitly created and runs under the SQL Server Agent service account. We recommend that you execute sp_addmergepushsubscription_agent and specify the credentials of a different, agent-specific Windows account for @job_login and @job_password. For more information, see Replication Agent Security Model.

-- 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 @publication AS sysname;
DECLARE @subscriber AS sysname;
DECLARE @subscriptionDB AS sysname;
DECLARE @hostname AS sysname;
SET @publication = N'AdvWorksSalesOrdersMerge';
SET @subscriber = $(SubServer);
SET @subscriptionDB = N'AdventureWorksReplica'; 
SET @hostname = N'adventure-works\david8'

-- Add a push subscription to a merge publication.
USE [AdventureWorks2012];
EXEC sp_addmergesubscription 
  @publication = @publication, 
  @subscriber = @subscriber, 
  @subscriber_db = @subscriptionDB, 
  @subscription_type = N'push',
  @hostname = @hostname;

--Add an agent job to synchronize the push subscription.
EXEC sp_addmergepushsubscription_agent 
  @publication = @publication, 
  @subscriber = @subscriber, 
  @subscriber_db = @subscriptionDB, 
  @job_login = $(Login), 
  @job_password = $(Password);
GO

Only members of the sysadmin fixed server role or db_owner fixed database role can execute sp_addmergesubscription.
