Hinweise
DatabaseName ist eine erforderliche Eigenschaft und muss gesetzt werden, bevor das Abonnement auf dem Server erstellt wird. Sobald die Abonnementregistrierung auf dem Server existiert, kann die Eigenschaft DatabaseName nicht mehr geändert werden.
Für eine Nicht-SQL Server Publisher wird die Eigenschaft DatabaseName auf den Namen der Verteilungsdatenbank gesetzt.
Die Eigenschaft DatabaseName kann nur von Mitgliedern der Sysadmin-Fixed-Server-Rolle am Publisher, von Mitgliedern der db_owner Fixed-Datenbank-Rolle in der Publikationsdatenbank oder vom Benutzer, der das Abonnement erstellt hat, abgerufen werden.
Die Eigenschaft DatabaseName kann nur von Mitgliedern der Sysadmin-Fixed-Server-Rolle am Publisher oder von Mitgliedern der db_owner Fixed-Datenbank-Rolle in der Publikationsdatenbank festgelegt werden.
Das Abrufen der DatabaseName Eigenschaft entspricht der Ausführung von sp_helpsubscription oder sp_helpmergesubscription.
Die Einstellung der DatabaseName Eigenschaft entspricht dem Ausführen von sp_addsubscription oder sp_addmergesubscription.
