Ich versuche, Registrierungsdaten in der Datenbank zu speichern. Es gibt zwei Tabellen - geregistry3 und getypes2. Einfügen funktioniert normalerweise in getypes2. Aber beim Einfügen von Daten in geregistry3 wird es entweder nicht gespeichert oder es wird nur ein Tupel gespeichert (das auch temporär wieder leer wird, wenn diese Aktivität neu gestartet wird), wenn ich die Datenbank nicht mit db.close() schließe. In allen Protokollen und Stacktraces werden keine Ausnahmen oder Fehler angezeigt.Kontinuierliche Speicherung von Daten in einer Datenbank
Bitte helfen!
