sp_addmergepushsubscription_agent (Transact-SQL)

  • Artikel

Applies to: SQL Server Azure SQL Managed Instance

Adds a new agent job used to schedule synchronization of a push subscription to a merge publication. This stored procedure is executed at the Publisher on the publication database.

Belangrijk

When configuring a Publisher with a remote Distributor, the values supplied for all parameters, including @job_login and @job_password, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before executing this stored procedure. For more information, see Configure SQL Server Database Engine for encrypting connections.

Transact-SQL syntax conventions

Notitie

Microsoft Entra ID was previously known as Azure Active Directory (Azure AD).

Arguments

[ @publication = ] N'publication'

The name of the publication. @publication is sysname, with no default.

[ @subscriber = ] N'subscriber'

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

[ @subscriber_db = ] N'subscriber_db'

The name of the subscription database. @subscriber_db is sysname, with a default of NULL.

[ @subscriber_security_mode = ] subscriber_security_mode

The security mode to use when connecting to a Subscriber when synchronizing. @subscriber_security_mode is smallint, with a default of 1. The following values define the security mode:

  • 0 specifies SQL Server authentication.
  • 1 specifies Windows authentication.
  • 2 specifies Microsoft Entra password authentication, starting with SQL Server 2022 (16.x) CU 6.
  • 3 specifies Microsoft Entra integrated authentication, starting with SQL Server 2022 (16.x) CU 6.
  • 4 specifies Microsoft Entra token authentication, starting with SQL Server 2022 (16.x) CU 6.

Belangrijk

When possible, use Windows authentication.

[ @subscriber_login = ] N'subscriber_login'

The Subscriber login to use when connecting to a Subscriber when synchronizing. @subscriber_login is sysname, with a default of NULL. @subscriber_login is required if @subscriber_security_mode is set to 0.

[ @subscriber_password = ] N'subscriber_password'

The Subscriber password for SQL Server Authentication. @subscriber_password is sysname, with a default of NULL. @subscriber_password is required if @subscriber_security_mode is set to 0. If a subscriber password is used, it's automatically encrypted.

Belangrijk

When possible, prompt users to enter security credentials at runtime. If you must store credentials in a script file, you must secure the file to prevent unauthorized access.

[ @publisher_security_mode = ] publisher_security_mode

The security mode to use when connecting to a Publisher when synchronizing. @publisher_security_mode is smallint, with a default of 1. The following values define the security mode:

  • 0 specifies SQL Server authentication.
  • 1 specifies Windows authentication.
  • 2 specifies Microsoft Entra password authentication, starting with SQL Server 2022 (16.x) CU 6.
  • 3 specifies Microsoft Entra integrated authentication, starting with SQL Server 2022 (16.x) CU 6.
  • 4 specifies Microsoft Entra token authentication, starting with SQL Server 2022 (16.x) CU 6.

Belangrijk

When possible, use Windows authentication.

[ @publisher_login = ] N'publisher_login'

The login to use when connecting to a Publisher when synchronizing. @publisher_login is sysname, with a default of NULL.

[ @publisher_password = ] N'publisher_password'

The password used when connecting to the Publisher. @publisher_password is sysname, with a default of NULL.

Belangrijk

Do not use a blank password. Use a strong password. When possible, prompt users to enter security credentials at runtime. If you must store credentials in a script file, you must secure the file to prevent unauthorized access.

[ @job_login = ] N'job_login'

The login for the Windows account under which the agent runs. @job_login is nvarchar(257), with a default of NULL. This Windows account is always used for agent connections to the Distributor and for connections to the Subscriber and Publisher when using Windows Integrated authentication.

[ @job_password = ] N'job_password'

The password for the Windows account under which the agent runs. @job_password is sysname, with no default.

Belangrijk

When possible, prompt users to enter security credentials at runtime. If you must store credentials in a script file, you must secure the file to prevent unauthorized access.

[ @job_name = ] N'job_name'

The name of an existing agent job. @job_name is sysname, with a default of NULL. This parameter is only specified when the subscription is synchronized using an existing job instead of a newly created job (the default). If you aren't a member of the sysadmin fixed server role, you must specify job_login and job_password when you specify @job_name.

[ @frequency_type = ] frequency_type

A value indicating when the Merge Agent runs. @frequency_type is int, and can be one of the following values.

Value Description
1 One time
2 On demand
4 Daily
8 Weekly
16 Monthly
32 Monthly relative
64 Autostart
128 Recurring

Notitie

Specifying a value of 64 causes the Merge Agent to run in continuous mode. This corresponds to setting the -Continuous parameter for the agent. For more information, see Replication Merge Agent.

5 Thursday
6 Friday
7 Saturday
8 Day
9 Weekdays
10 Weekend days
NULL (default)

[ @frequency_relative_interval = ] frequency_relative_interval

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

[ @frequency_recurrence_factor = ] frequency_recurrence_factor

The recurrence factor used by @frequency_type. @frequency_recurrence_factor is int, with a default of 0.
