The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 10: Integrating FILESTREAM with other SQL Server FeaturesListing 10-2 shows how to set this option to true using T-SQL for a merge publication.EXEC sp_changemergepublication@publication = 'northpole',@property = N'replicate_ddl',@value = 1,@force_invalidate_snapshot = 0,@force_reinit_subscription = 0;Listing 10-2:T-SQL script to update the replicate_ddl option of a publication.MSDN documentation says that, if a UNIQUE constraint has been added manually andyou wish to remove replication, the UNIQUE constraint should be removed first. If theUNIQUE constraint is not removed before attempting to drop the publication, the dropoperation will fail. I could not replicate this behavior during my testing, but keep this inmind while replicating FILESTREAM columns.Managing the FILESTREAM replication flag usingT-SQLIn the previous section we learned that a FILESTREAM column can be replicatedwith or without the FILESTREAM attribute. Then we saw how to change theconfiguration to replicate the FILESTREAM attribute or disable the replication ofthe FILESTREAM attribute using the SSMS dialog boxes. Here, we examine how theFILESTREAM replication flag can be managed using T-SQL; in other words, how toenable and disable the replication of the FILESTREAM attribute using the replicationsystem stored procedures.360
