Comentários

Calling AddMergeDynamicSnapshotJob is equivalent to executing sp_adddynamicsnapshot_job.

The AddMergeDynamicSnapshotJob method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

The AddMergeDynamicSnapshotJob method is supported for Microsoft SQL Server 2000 and later versions.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.
