Hinweise

WHERE ist nicht in der Filterklausel enthalten.

Wenn Sie festlegen FilterClause , nachdem die anfängliche Momentaufnahme erstellt wurde, muss eine neue Momentaufnahme generiert werden.

Die FilterClause Eigenschaft kann von Mitgliedern der festen Serverrolle sysadmin beim Verleger und beim Abonnenten (für die erneute Veröffentlichung von Abonnenten) abgerufen werden. Sie kann auch von Mitgliedern der db_owner festen Datenbankrolle in der Veröffentlichungsdatenbank, von Mitgliedern der festen Datenbankrolle replmonitor beim Verteiler und von Benutzern abgerufen werden, die Mitglieder der Veröffentlichungszugriffsliste (PAL) sind.

Die FilterClause -Eigenschaft kann von Mitgliedern der festen Serverrolle sysadmin auf dem Verleger festgelegt werden. Sie kann auch von Mitgliedern der db_owner festen Datenbankrolle in der Veröffentlichungsdatenbank festgelegt werden.

Das Abrufen FilterClause entspricht der Ausführung sp_helpmergearticle (Transact-SQL).

Die Einstellung FilterClause entspricht der Ausführung sp_addmergearticle (Transact-SQL) oder sp_changemergearticle (Transact-SQL).
