データベースのフィールドに同じ値がなければデータを保存し、データベースのフィールドに同じ値があればデータを更新するプログラムを作成しました。

「休止状態」がデータベースの値を確認できるようにするのに行き詰まりました

事前に感謝します。

これで、データが存在するかどうかを確認するための休止状態の条件を指定できます...条件が真の場合、このコードは機能しますが、条件が偽の場合、エラーが発生しました...

            Query query = session.createQuery("from CoreService where MODULE_NAME= :lolo1 and OBJECT_NAME= :lolo2 and SYSTEM_ID= :lolo3 and LOG_DATE= :lolo4");
            query.setParameter("lolo1", module);
            query.setParameter("lolo2", object);
            query.setParameter("lolo3", system_id);
            query.setParameter("lolo4", log_date);

            @SuppressWarnings("unchecked")
            List<CoreService> result = query.list();
            if(result.isEmpty()){
                System.out.println("LOLOH");

                CoreService data = new CoreService();
                data.setMODULE_NAME(module);
                data.setCATEGORY("SYSTEMID");
                data.setSYSTEM_ID(system_id);
                data.setCOUNTER_SYSTEM(1);
                data.setOBJECT_NAME(object);
                data.setCOUNTER_SERVICE(1);
                data.setLOG_DATE(log_date);
                data.setUPDATE_LOG(update_log);

                session.beginTransaction();
                session.save(data);
                session.getTransaction().commit();

            }else{
                System.out.println("LELEH");

                CoreService data = new CoreService();

                data.setCATEGORY("SYSTEMID");

                data.setCOUNTER_SYSTEM(2);

                data.setCOUNTER_SERVICE(2);



                session.beginTransaction();
                session.update(data);
                session.getTransaction().commit();

            }

ここにエラーがあります〜

Else ブロックでは、結果からデータを取得し、必要な値を設定する必要があります。

else{
                System.out.println("LELEH");

                CoreService data = (CoreService )result.get(0);

                data.setCATEGORY("SYSTEMID");

                data.setCOUNTER_SYSTEM(2);

                data.setCOUNTER_SERVICE(2);



                session.beginTransaction();
                session.update(data);
                session.getTransaction().commit();

            }
