Changes the properties of a merge article. This stored procedure is executed at the Publisher on the publication database.
sp_changemergearticle [ @publication = ] 'publication' , [ @article = ] 'article' [ , [ @property = ] 'property' ] [ , [ @value = ] 'value' ] [ , [ @force_invalidate_snapshot = ] force_invalidate_snapshot ] [ , [ @force_reinit_subscription = ] force_reinit_subscription ]
[ **@publication=**] 'publication'
Is the name of the publication in which the article exists. publication is sysname, with no default.
[ **@article=**] 'article'
Is the name of the article to change. article is sysname, with no default.
[ **@property=**] 'property'
Is the property to change for the given article and publication. property is nvarchar(30), and can be one of the values listed in the table.
[ **@value=**] 'value'
Is the new value for the specified property. value is nvarchar(1000), and can be one of the values listed in the table.
This table describes the properties of articles and the values for those properties.
|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: 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 ** 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 ** 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: 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.|

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.|

|0x01||Generates the object creation script (CREATE TABLE, CREATE PROCEDURE, and so on).|
|0x10||Generates a corresponding clustered index.|
|0x20||Converts user-defined data types to base data types at the Subscriber. This option cannot be used when there is a CHECK or DEFAULT constraint on a user-defined type (UDT) column, if a UDT column is part of the primary key, or if a computed column references a UDT column.|
|0x40||Generates corresponding nonclustered indexes.|
|0x80||Includes declared referential integrity on the primary keys.|
|0x100||Replicates user triggers on a table article, if defined.|

|0x10000000||Converts xml columns to ntext on the Subscriber.|
|0x20000000||Converts large object data types (nvarchar(max), varchar(max), and varbinary(max)) that were introduced in SQL Server 2005 (9.x) to data types that are supported on SQL Server 2000 (8.x).|

|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 (9.x) Subscribers. Replicating tables that have FILESTREAM columns to SQL Server 2000 (8.x) Subscribers is not supported, regardless of how this schema option is set. See related option 0x800000000.|

|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 (9.x).|
|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 (9.x). 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 (9.x).|
|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 ** 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 ** For performance reasons, we recommended that you not apply functions to column names in parameterized row filter clauses, such as
|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.
Return Code Values
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:
Changing the following properties requires that existing subscriptions be reinitialized, and you must specify a value of 1 for the force_reinit_subscription parameter:
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.
When you many (perhaps hundreds) of articles in a publication and you execute sp_changemergearticle for one of the articles, it might take a long time to finish execution.
