Vi sono alcune possibili soluzioni alternative:
Evita l'uso del simbolo "<" modificando l'istruzione SQL. Ad esempio:
Da: tableA.ActDate >= tableB.startDate AND tableA.ActDate <= tableB.endDate
A: tableA.ActDate BETWEEN tableB.startDate AND tableB.endDate
Converti il campo data con tipo di dati STRING in un tipo di dati DATE nell'istruzione SQL. Ad esempio:
TO_DATE(tableA.ActDate,'YYYY/MM/DD') as ActDate
