How to: View Conflict Information for Merge Publications (Replication Transact-SQL Programming)
When a conflict is resolved in merge replication, the data from the losing row is written to a conflict table. This conflict data can be viewed programmatically by using replication stored procedures. For more information, see Détection et résolution avancées des conflits de réplication de fusion.
To view conflict information and losing row data for all types of conflicts
At the Publisher on the publication database, execute sp_helpmergepublication. Note the values of the following columns in the result set:
- centralized_conflicts - 1 indicates that conflict rows are stored at the Publisher, and 0 indicates that conflict rows are not stored at the Publisher.
- decentralized_conflicts - 1 indicates that conflict rows are stored at the Subscriber, and 0 indicates that conflict rows are not stored at the Subscriber.

Remarque :The conflict logging behavior of a merge publication is set by using the @conflict_logging parameter of sp_addmergepublication. Use of the @centralized_conflicts parameter has been deprecated.
The following table describes the values of these columns based on the value specified for @conflict_logging.

At either the Publisher on the publication database or at the Subscriber on the subscription database, execute sp_helpmergearticleconflicts. Specify a value for @publication to only return conflict information for articles that belong to a specific publication. This returns conflict table information for articles with conflicts. Note the value of conflict_table for any articles of interest. If the value of conflict_table for an article is NULL, only delete conflicts have occurred in this article.
(Optional) Review conflict rows for articles of interest. Depending on the values of centralized_conflicts and decentralized_conflicts from step 1, do one of the following:
- At the Publisher on the publication database, execute sp_helpmergeconflictrows. Specify a conflict table for the article (from step 1) for @conflict_table. (Optional) Specify a value of @publication to restrict returned conflict information to a specific publication. This returns row data and other information for the losing row.
- At the Subscriber on the subscription database, execute sp_helpmergeconflictrows. Specify a conflict table for the article (from step 1) for @conflict_table. This returns row data and other information for the losing row.
To view information only on conflicts where the delete failed
At the Publisher on the publication database, execute sp_helpmergepublication. Note the values of the following columns in the result set:
- centralized_conflicts - 1 indicates that conflict rows are stored at the Publisher, and 0 indicates that conflict rows are not stored at the Publisher.
- decentralized_conflicts - 1 indicates that conflict rows are stored at the Subscriber, and 0 indicates that conflict rows are not stored at the Subscriber.Remarque :

(Optional) Review conflict information for delete conflicts. Depending on the values of centralized_conflicts and decentralized_conflicts from step 1, do one of the following:
- At the Publisher on the publication database, execute sp_helpmergedeleteconflictrows. Specify the name of the source table (from step 1) on which the conflict occurred for @source_object. (Optional) Specify a value of @publication to restrict returned conflict information to a specific publication. This returns delete conflict information stored at the Publisher.
- At the Subscriber on the subscription database, execute sp_helpmergedeleteconflictrows. Specify the name of the source table (from step 1) on which the conflict occurred for @source_object. (Optional) Specify a value of @publication to restrict returned conflict information to a specific publication. This returns delete conflict information stored at the Subscriber.
