Es gibt ein paar mögliche Problemumgehungen:
Vermeiden Sie die Verwendung des Symbols "<" durch Änderung der SQL-Anweisung. Zum Beispiel:
Von: tableA.ActDate >= tableB.startDate AND tableA.ActDate <= tableB.endDate
Zu : tableA.ActDate BETWEEN tableB.startDate AND tableB.endDate
Konvertieren Sie das Datumsfeld mit dem Datentyp STRING zu dem Datentyp DATE in der SQL-Anweisung. Zum Beispiel:
TO_DATE(tableA.ActDate,'YYYY/MM/DD') as ActDate
001472082
