Property

Values

Description

allow_interactive_resolver

true

Enables the use of an interactive resolver for the article.

 

false

Disables the use of an interactive resolver for the article.

article_resolver

 

Custom resolver for the article. Applies only to a table article.

check_permissions (bitmap)

0x00

Table-level permissions are not checked.

 

0x10

Table-level permissions are checked at the Publisher before INSERT statements made at the Subscriber are applied at the Publisher.

 

0x20

Table-level permissions are checked at the Publisher before UPDATE statements made at the Subscriber are applied at the Publisher.

 

0x40

Table-level permissions are checked at the Publisher before DELETE statements at the Subscriber are applied at the Publisher.

column_tracking

true

Turns on column level tracking. Applies only to a table article.

Note Note

Column level tracking cannot be used when publishing tables with more than 246 columns.

 

false

Turns off column level tracking and leaves conflict detection at the row level. Applies only to a table article.

compensate_for_errors

true

Compensating actions are performed when errors occur during synchronization. For more information, see sp_addmergearticle.

 

false

Compensating actions are not performed, which is the default behavior. For more information, see sp_addmergearticle.

Important note Important

Although data in the affected rows might appear to be out of convergence, as soon as you address any errors, changes can be applied and data will converge. If the source table for an article is already published in another publication, then the value of compensate_for_errors must be the same for both articles.

creation_script

 

Path and name of an optional article schema script used to create the article in the subscription database.

delete_tracking

true

DELETE statements are replicated, which is the default behavior.

 

false

DELETE statements are not replicated.

Important note Important

Setting delete_tracking to false results in non-convergence, and deleted rows need to be manually removed.

description

 

Descriptive entry for the article.

destination_owner

 

Name of the owner of the object in the subscription database, if not dbo.

identity_range

 

bigint that specifies the range size to use when assigning new identity values if the article has identityrangemanagementoption set to auto or auto_identity_range set to true. Applies to a table article only. For more information, see the "Merge Replication" section of Replicate Identity Columns.

identityrangemanagementoption

manual

Disables automatic identity range management. Marks identity columns using NOT FOR REPLICATION to enable manual identity range handling. For more information, see Replicate Identity Columns.

 

none

Disables all identity range management.

logical_record_level_conflict_detection

true

A conflict is detected if changes are made anywhere in the logical record. Requires that logical_record_level_conflict_resolution be set to true.

 

false

Default conflict detection is used as specified by column_tracking.

logical_record_level_conflict_resolution

true

Entire winning logical record overwrites the losing logical record.

 

false

Winning rows are not constrained to the logical record.

partition_options

0

The filtering for the article either is static or does not yield a unique subset of data for each partition, i.e. an "overlapping" partition.

 

1

The partitions are overlapping, and DML updates made at the Subscriber cannot change the partition to which a row belongs.

 

2

The filtering for the article yields non-overlapping partitions, but multiple Subscribers can receive the same partition.

 

3

The filtering for the article yields non-overlapping partitions that are unique for each subscription.

Note Note

If you specify a value of 3 for partition_options, there can be only a single subscription for each partition of data in that article. If a second subscription is created in which the filtering criterion of the new subscription resolves to the same partition as the existing subscription, the existing subscription is dropped.

pre_creation_command

none

If the table already exists at the Subscriber, no action is taken.

 

delete

Issues a delete based on the WHERE clause in the subset filter.

 

drop

Drops the table before re-creating it.

 

truncate

Truncates the destination table.

processing_order

 

int that indicates the processing order of articles in a merge publication.

pub_identity_range

 

bigint that specifies the range size allocated to a Subscriber with a server subscription if the article has identityrangemanagementoption set to auto or auto_identity_range set to true. This identity range is reserved for a republishing Subscriber to allocate to its own Subscribers. Applies to a table article only. For more information, see the "Merge Replication" section of Replicate Identity Columns.

published_in_tran_pub

true

Article is also published in a transactional publication.

 

false

Article is not also published in a transactional publication.

resolver_info

 

Is used to specify additional information required by a custom resolver. Some of the Microsoft Resolvers require a column provided as input to the resolver. resolver_info is nvarchar(255), with a default of NULL. For more information, see Microsoft COM-Based Resolvers.

0x40000000

Replicate permissions.

 

0x80000000

Attempt to drop dependencies to any objects that are not part of the publication.

0x100000000

Use this option to replicate the FILESTREAM attribute if it is specified on varbinary(max) columns. Do not specify this option if you are replicating tables to SQL Server 2005 Subscribers. Replicating tables that have  FILESTREAM columns to SQL Server 2000 Subscribers is not supported, regardless of how this schema option is set. See related option 0x800000000.

0x200000000

Converts date and time data types (date, time, datetimeoffset, and datetime2) that are introduced in SQL Server 2008 to data types that are supported on earlier versions of SQL Server.

0x400000000

Replicates the compression option for data and indexes. For more information, see Data Compression.

0x800000000

Set this option to store FILESTREAM data on its own filegroup at the Subscriber. If this option is not set, FILESTREAM data is stored on the default filegroup. Replication does not create filegroups; therefore, if you set this option, you must create the filegroup before you apply the snapshot at the Subscriber. For more information about how to create objects before you apply the snapshot, see Execute Scripts Before and After the Snapshot Is Applied.

See related option 0x100000000.

0x1000000000

Converts common language runtime (CLR) user-defined types (UDTs) to varbinary(max) so that columns of type UDT can be replicated to Subscribers that are running SQL Server 2005.

0x2000000000

Converts the hierarchyid data type to varbinary(max) so that columns of type hierarchyid can be replicated to Subscribers that are running SQL Server 2005. For more information about how to use hierarchyid columns in replicated tables, see hierarchyid (Transact-SQL).

0x4000000000

Replicates any filtered indexes on the table. For more information about filtered indexes, see Create Filtered Indexes.

 

0x8000000000

Converts the geography and geometry data types to varbinary(max) so that columns of these types can be replicated to Subscribers that are running SQL Server 2005.

 

0x10000000000

Replicates indexes on columns of type geography and geometry.

 

NULL

System auto-generates a valid schema option for the article.

status

active

Initial processing script to publish the table is run.

 

unsynced

The initial processing script to publish the table is run the next time the Snapshot Agent runs.

stream_blob_columns

true

A data stream optimization is used when replicating binary large object columns. However, certain merge replication functionalities, such as logical records, can still prevent the stream optimization from being used. stream_blob_columns is set to true when FILESTREAM is enabled. This allows replication of FILESTREAM data to perform optimally and reduce memory utilization. To force FILESTREAM table articles to not use blob streaming, set stream_blob_columns to false.

Important note Important

Enabling this memory optimization might hurt the performance of the Merge Agent during synchronization. This option should only be used when replicating columns that contain megabytes of data.

 

false

The optimization is not used when replicating binary large object columns.

subscriber_upload_options

0

No restrictions on updates made at a Subscriber with a client subscription; changes are uploaded to the Publisher. Changing this property may require that existing Subscribers be reinitialized.

 

1

Changes are allowed at a Subscriber with a client subscription, but they are not uploaded to the Publisher.

 

2

Changes are not allowed at a Subscriber with a client subscription.

subset_filterclause

 

WHERE clause specifying the horizontal filtering. Applies only to a table article.

Important note Important

For performance reasons, we recommended 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, you might have to convert data types by using CONVERT. For more information about best practices for this case, see the section "Overriding the HOST_NAME() Value" in Parameterized Row Filters.

threshold

 

Percentage value used for Subscribers running SQL Server Compact or earlier versions of SQL Server. threshold controls when the Merge Agent assigns a new identity range. When the percentage of values specified in threshold is used, the Merge Agent creates a new identity range. Used when identityrangemanagementoption is set to auto or auto_identity_range is set to true. Applies to a table article only. For more information, see the "Merge Replication" section of Replicate Identity Columns.

verify_resolver_signature

1

Digital signature on a custom resolver is verified to determine if it is from a trusted source.

 

0

Digital signature on a custom resolver is not verified to determine if it is from a trusted source.

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 merge 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 means that changes to the merge article may cause the snapshot to be invalid, and if there are existing subscriptions that would require a new snapshot, 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 merge 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 means that changes to the merge article cause existing subscriptions to be reinitialized, and gives permission for the subscription reinitialization to occur.

See the Remarks section for the properties that, when changed, require that all existing subscriptions be reinitialized.

0 (success) or 1 (failure)

sp_changemergearticle is used in merge replication.

Because sp_changemergearticle is used to change article properties that were initially specified by using sp_addmergearticle, refer to sp_addmergearticle for additional information about these properties.

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

  • check_permissions

  • column_tracking

  • destination_owner

  • pre_creation_command

  • schema_options

  • subset_filterclause

Changing the following properties requires that existing subscriptions be reinitialized, and you must specify a value of 1 for the force_reinit_subscription parameter:

  • check_permissions

  • column_tracking

  • destination_owner

  • pre_creation_command

  • identityrangemanagementoption

  • subscriber_upload_options

  • subset_filterclause

  • creation_script

  • schema_option

  • logical_record_level_conflict_detection

  • logical_record_level_conflict_resolution

When specifying a value of 3 for partition_options, metadata is cleaned up whenever the Merge Agent runs and the partitioned snapshot expires more quickly. When using this option, you should consider enabling subscriber requested partitioned snapshot. For more information, see Snapshots for Merge Publications with Parameterized Filters.

When setting the column_tracking property, if the table is already published in other merge publications, the column tracking must be the same as the value being used by existing articles based on this table. This parameter is specific to table articles only.

If multiple publications publish articles based on the same underlying table, changing the delete_tracking property or the compensate_for_errors property for one article causes the same change to be made to the other articles that are based on the same table.

If the Publisher login/user account used by the merge process does not have the correct table permissions, the invalid changes are logged as conflicts.

When changing the value of schema_option, the system does not perform a bitwise update. This means that when you set schema_option using sp_changemergearticle, existing bit settings may be turned off. To retain the existing settings, you should perform & (Bitwise AND) between the value that you are setting and the current value of schema_option, which can be determined by executing sp_helpmergearticle.
