CTE-Code nur greifen Anker nicht machen Rekursion

Abfrage führt nicht die Rekursion, es holt nur den Anker Teil (die IDs wo Eltern-ID ist Null).CTE-Code nur greifen Anker nicht machen Rekursion

Kann mir jemand helfen, meinen Fehler zu erkennen? Ich habe viele Dinge ausprobiert, aber ich finde immer die gleiche Anzahl von Zeilen, die IDS ohne Eltern-IDs.

You can see in the link the two columns data types where the recursion is being made, it is a nvarchar(256)

Vielen Dank, ich weiß, es ist etwas recht einfach sein, aber ich kann nicht herausfinden.

können Sie einige Testdaten gemeinsam nutzen als DML – TheGameiswar

Ups, sorry guys, da mein Problem nur das select ist und Joins nicht funktionieren Ich dachte, dass keine Daten notwendig wären. Der Kern dieses Problems ist nur auf file_guid und fileparent_guid. Ich gebe Informationen über den Datentyp –

Dies ist die Antwort basierend auf Kommentare früher:

Die Lösung war, dass er kein Spiel hatte, wo sie null waren - Er hatte sie in erster passen wählen.
