Java SQLite JDBC - Вставка с помощью автоинкремента

-1

Я использую SQLite-JDBC-3.8.1 (см. https://bitbucket.org/xerial/sqlite-jdbc/downloads), и я просто хочу вставить кортеж в таблицу, где мой первичный ключ автоматически увеличивается.Java SQLite JDBC - Вставка с помощью автоинкремента

Таблица создается как

CREATE TABLE image (
     ID INTEGER PRIMARY KEY, 
     PATH TEXT, 
     NAME TEXT 
);

Я использую SQLite JDBC для подключения к базе данных. У меня есть метод

public int insertImage(String path, String name) 
{ 
    int newID = -1; 

    try 
    { 
     stmt = connect.createStatement(); 
     if(stmt == null) 
     { 
      System.out.println("Abort: Could not create statement."); 
      return -1; 
     } 
     else 
     { 
      stmt.executeUpdate("INSERT INTO image (path, name) VALUES(\"" + path +"\", \"" + name + "\")"); 
      System.out.println("NOCH OK"); 
      //resultSet = stmt.getGeneratedKeys(); 

      if(resultSet.next()) 
       newID = resultSet.getInt(1); 

      return newID; 
     } 
    } 
    catch(SQLException ex) 
    { 
     System.out.println("An unexpected error occured: Statement \"INSERT INTO image (path, name) VALUES [...]\" could not be executed properly."); 
     System.out.println("SQLExeption: " + ex.getMessage()); 
     System.out.println("SQLState: " + ex.getSQLState()); 
     System.out.println("VendorError: " + ex.getErrorCode()); 

     return -1; 
    } 
    finally 
    { 
     close("insertImage"); 
    } 
}

который должен вставить новый кортеж в данную таблицу. Но каждый раз, когда я получаю ошибку.

An unexpected error occured: Statement "INSERT INTO image (path, name) VALUES [...]" could not be executed properly. SQLExeption: NOT NULL constraint failed: image.ID SQLState: null VendorError: 0

Я не знаю, почему Java и JDBC говоря мне image.ID NOT NULL ограничение. Использование командной строки с помощью одного и того же оператора просто отлично работает. Я искал в Интернете около 1 часа, но, похоже, нет ответа на это поведение.

java.sql.SQLException: NOT NULL constraint failed: image.ID

РЕШИТЬ: Я идиот ... У меня есть две базы данных (один в ../program/database/images.db и один в ../program/images.db), и я случайно загрузил неправильную базу данных в моем приложении. Сейчас все работает отлично. <

Почему это имеет значение? Я использовал MySQL JDBC раньше ... с MySQL данный метод/оператор просто отлично работал. Кажется, проблема с SQLite или, возможно, с его JDBC ... –

Я читаю несколько изображений, получаю их файловые пути и имена файлов и просто вызываю этот insertImage (путь, имя) из другого класса. На самом деле это не проблема. Кажется, что есть некоторые проблемы с AUTOINCREMENT в SQLite –

Вы делаете много вещей, которые делают эту работу сложнее, чем она должна быть:

Использование PreparedStatement и связать переменные
Печать или войти трассировки стека вместо печати сообщений, которые имеют за вычетом информации
Заявление о закрытии и ResultSet в конце блока

Stack Trace есть. Я также попробовал PrepStatements, по-прежнему получил ту же ошибку. Заявления закрываются должным образом в блоке finally (close ("insertImage") вызывает метод, при котором все операторы закрываются) –

Нет, я не сделал это неправильно. Трассировки стека не было раньше. – duffymo
