Artikel können nicht mehr bearbeiten werden | Uncaught RuntimeException: SQL Error!

[GuidoB.]

Hallo,

ich habe offenbar ein Problem mit meiner Datenbank.
Ich kann im Adminbereich keine Artikel mehr bearbeiten.

Folgende Fehler wird im Log hinterlegt: Uncaught RuntimeException: SQL Error!

Der Gesamte Log Eintrag sieht wie folgt aus:
