Un BusinessLogicHandler oggetto che rappresenta il gestore di logica business che viene registrato.

Commenti

Il gestore di logica aziendale deve essere registrato presso il Distributore (e presso l'Abbonato nel caso di un abbonamento pull). Tuttavia, l'assembly che implementa il business logic handler deve essere installato solo sul server su cui viene eseguito il agente di merge.

Il <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> metodo può essere chiamato solo dai membri del sysadmin ruolo fisso del server e dai membri del db_owner ruolo fisso del database

Chiamare <xref:Microsoft.SqlServer.Replication.ReplicationServer.RegisterBusinessLogicHandler%2A> è equivalente all'esecuzione di sp_registercustomresolver.
