    immediate_sync

    true

    Synchronization files for the publication are created or re-created each time the Snapshot Agent runs. Subscribers are able to receive the synchronization files immediately after the subscription if the Snapshot Agent has been completed once before the subscription. New subscriptions get the newest synchronization files generated by the most recent execution of the Snapshot Agent. independent_agent must also be true.

     

    false

    Synchronization files are created only if there are new subscriptions. Subscribers cannot receive the synchronization files after the subscription until the Snapshot Agent is started and completes.

    independent_agent

    true

    Publication has its own dedicated Distribution Agent.

     

    false

    Publication uses a shared Distribution Agent, and each publication/subscription database pair has a shared agent.

    p2p_continue_onconflict

    true

    The Distribution Agent continues to process changes when a conflict is detected.

    Caution noteCaution
    We recommend that you use the default value of FALSE. When this option is set to TRUE, the Distribution Agent tries to converge data in the topology by applying the conflicting row from the node that has the highest originator ID. This method does not guarantee convergence. You should make sure that the topology is consistent after a conflict is detected. For more information, see "Handling Conflicts" in Conflict Detection in Peer-to-Peer Replication.

    false

    The Distribution Agent stops processing changes when a conflict is detected.

    post_snapshot_script

    false

    Removes the publication information from Active Directory.

    queue_type

    sql

    Use SQL Server to store transactions. This property can be changed only if there are no active subscriptions.

    NoteNote
    Support for using Microsoft Message Queuing has been discontinued. Specifying a value of msmq for value results in an error.

    repl_freq

    continuous

    Publishes output of all log-based transactions.

     

    snapshot

    Publishes only scheduled synchronization events.

    replicate_partition_switch

    true

    ALTER TABLE…SWITCH statements that are executed against the published database should be replicated to Subscribers. This option is valid only if allow_partition_switch is set to TRUE. For more information, see Replicating Partitioned Tables and Indexes.

    false

    ALTER TABLE…SWITCH statements should not be replicated to Subscribers.

    retention

     

    int representing the retention period, in hours, for subscription activity. If a subscription is not active within the retention period, it is removed.

    snapshot_in_defaultfolder

    true

    Snapshot files are stored in the default snapshot folder. If alt_snapshot_folderis also specified, snapshot files are stored in both the default and alternate locations.

     

    false

    Snapshot files are stored in the alternate location specified by alt_snapshot_folder.

    status

    character

    Uses character-mode bulk copy output of all tables when synchronizing subscriptions.

     

    concurrent

    Uses native-mode bulk-copy program output of all tables, but does not lock tables during the snapshot generation process. Not valid for snapshot replication.

     

    concurrent_c

    Uses character-mode bulk copy program output of all tables, but does not lock tables during the snapshot generation process. Not valid for snapshot replication.

    taskid

     

    This property has been deprecated and is no longer supported.

    NULL (default)

     

    Returns the list of supported values for property.

  • [ @force_invalidate_snapshot = ] force_invalidate_snapshot
    Acknowledges that the action taken by this stored procedure may invalidate an existing snapshot. force_invalidate_snapshot is a bit, with a default of 0.

    0 specifies that changes to the article do not cause the snapshot to be invalid. If the stored procedure detects that the change does require a new snapshot, an error occurs and no changes are made.

    1 specifies that changes to the article may cause the snapshot to be invalid. If there are existing subscriptions that would require a new snapshot, this value gives permission for the existing snapshot to be marked as obsolete and a new snapshot generated.

    See the Remarks section for the properties that, when changed, require the generation of a new snapshot.

  • [@force_reinit_subscription = ] force_reinit_subscription
    Acknowledges that the action taken by this stored procedure may require existing subscriptions to be reinitialized. force_reinit_subscription is a bit with a default of 0.

    0 specifies that changes to the article do not cause the subscription to be reinitialized. If the stored procedure detects that the change would require existing subscriptions to be reinitialized, an error occurs and no changes are made.

    1 specifies that changes to the article cause the existing subscription to be reinitialized, and gives permission for the subscription reinitialization to occur.

  • [ @publisher = ] 'publisher'
    Specifies a non-SQL Server Publisher. publisher is sysname, with a default of NULL.

    Note

    publisher should not be used when changing article properties on a SQL Server Publisher.

Return Code Values

0 (success) or 1 (failure)

Remarks

sp_changepublication is used in snapshot replication and transactional replication.

Changing any of the following properties requires that a new snapshot be generated, and you must specify a value of 1 for the force_invalidate_snapshot parameter.

  • alt_snapshot_folder

  • compress_snapshot

  • enabled_for_het_sub

  • ftp_address

  • ftp_login

  • ftp_password

  • ftp_port

  • ftp_subdirectory

  • post_snapshot_script

  • pre_snapshot_script

  • snapshot_in_defaultfolder

  • sync_mode

To list publication objects in the Active Directory using the publish_to_active_directory parameter, the SQL Server object must already be created in the Active Directory.

Example

DECLARE @publication AS sysname
SET @publication = N'AdvWorksProductTran' 

-- Turn off DDL replication for the transactional publication.
USE [AdventureWorks]
EXEC sp_changepublication 
  @publication = @publication, 
  @property = N'replicate_ddl', 
  @value = 0
GO

Permissions

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