Вопрос:
Проблема с курсором Android SQLite при cur3 = db3.rawQuery ниже приведены мои ошибки logcat и весь код класса. Я сталкиваюсь с проблемой восстановления данных на основе сравнения двух таблиц и первичного ключа (pretest_id) первой таблицы предварительной проверки. Я не понимаю, что не так в моем SQL-запросе.
Ошибки Logcat:

1. Несмотря на то, что я изменил свой запрос, он также не работает
Ответ №1:
У вас есть лишнее «,» прямо перед вашим WHERE в вашем заявлении. Кроме того, как указал Херб, у вас нет FROM в вашем выборе.
Ответ №2:
в вашем запросе нет раздела «from»
