Returns the name of the originating Publisher for a published database participating in a database mirroring session. This function is executed at a Publisher instance of SQL Server on the publication database. Use it to determine the original Publisher of the published database.
PUBLISHINGSERVERNAME is used in all types of replication.
PUBLISHINGSERVERNAME is used when a database mirroring session exists on the publication database between the Publisher and a mirror partner instance.
This function must be executed within the context of a publication database. When PUBLISHINGSERVERNAME is executed on a publication database at the mirror server instance of SQL Server, the name of the Publisher instance from which the published database originates is returned. When this function is executed on a database at the mirror server instance that is not published or that is published from the mirror server instance after a failover, the name of the mirror server instance is returned. When this function is executed at the original Publisher instance, the name of the Publisher is returned.
