java.sql.SQLSyntaxErrorException при попытке обновить строковое поле

Question

Моя база данных настроена в phpMyAdmin, и в моем запросе ниже я пытаюсь обновить строковое поле, содержащее путь к файлу некоторого программного обеспечения, например что-то вроде 'C: \ Program Files (x86) \ Kaspersky Lab \ KasperskyTotal Security 19.0.0 \ avp.exe '.

Когда я выполняю запрос, я получаю исключение java.sql.SQLSyntaxErrorException, как показано ниже.Этот запрос прекрасно работает при запуске в самом phpMyAdmin.Что я делаю неправильно?

Мой запрос:

String query4 = MessageFormat.format("UPDATE system_object SET file_path = {0}, validate={1} " +
            "where category_key = 2", settings.getAntivirus_filePath(), settings.isAntivirus_validate());

РЕДАКТИРОВАТЬ Я пытался использовать кавычки для моих параметров, но потом я просто получаютакая же ошибка

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '0}, validate=true where category_key = 2' at line 1 

Answer 1

Измените свой код так:

String query4 = MessageFormat.format(
            "UPDATE system_object SET file_path = \"{0}\", validate=\"{1}\" " +
            "where category_key = 2", "demo1", 
            "demo2");
    System.out.println(query4);

Выход: UPDATE system_object SET file_path = "demo1", validate="demo2" where category_key = 2

Answer 2

Используйте PreparedStatement и параметры привязки;Ваш текущий подход уязвим для инъекций SQL.Игнорируя это беспокойство (и это большое беспокойство), вы не цитируете свои параметры.Вы могли бы сделать

String query4 = MessageFormat.format(
        "UPDATE system_object SET file_path = '{0}', validate='{1}' " +
        "where category_key = 2", settings.getAntivirus_filePath(), 
        settings.isAntivirus_validate());

Answer 3

Просто для обновления используйте двойной символ '' вместо одного ':

String query4 = MessageFormat.format(
        "UPDATE system_object SET file_path = '{0}', validate='{1}' " +
        "where category_key = 2", settings.getAntivirus_filePath(), 
        settings.isAntivirus_validate());
