Versuchen Sie zunächst die in dieser DBA.SE-Antwort angegebene Abfrage, um Elemente zu finden, die mit Zertifikaten und asymmetrischen Schlüsseln verknüpft sind. Antwort:
Finden Sie signierte Prozeduren, Funktionen, Trigger, Assemblys und nach welchen Zertifikaten / asymmetrischen Schlüsseln
Wenn dadurch keine Objekte zurückgegeben werden, versuchen Sie als Nächstes die folgenden Abfragen, nach denen gesucht wird:
- Anmeldungen
- Benutzer
- Service Broker-Endpunkte
- Datenbankspiegelungsendpunkte
- Symmetrische Tasten
- Datenbankverschlüsselungsschlüssel (für TDE verwendet)
Bitte beachten Sie, dass Anmeldungen auf Server- / Instanzebene erfolgen, während alles andere auf Datenbankebene erfolgt. Außerdem werden Datenbankverschlüsselungsschlüssel auf Datenbankebene in einer DMV gemeldet, die Daten für alle Datenbanken zurückgibt und sich daher nicht basierend auf der "aktuellen" Datenbank ändert.
