MS Access データベースにデータセットを追加したいと考えています。しかし、SQL ステートメントの executeUpdate ステートメントで常に構文エラーが発生します。誰かが私を助けることができれば、それは素晴らしいことです.

ここにエラーが表示されます：

そして、これはエラーが基づいているコードです。それはexecuteUpdate() - Statement にあります:

try {

    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    Connection conn = DriverManager.getConnection("jdbc:odbc:MSAccess");
    PreparedStatement pstm;
    pstm = conn.prepareStatement("Insert Into Benutzer (Benutzername, Vorname, Nachname, E-Mail) values (?,?,?,?)");

    // SQL Statements
    pstm.setString(1, gui.benutzername.getText());
    pstm.setString(2, gui.vorname.getText());
    pstm.setString(3, gui.nachname.getText());
    pstm.setString(4, gui.email.getText());
    pstm.executeUpdate();

    } catch (Exception e) {
        e.printStackTrace();
    }

構文エラーが見つかりません! 誰かが私を助けることができますか？

ありがとうございました

テーブルのすべての列の値を追加する必要があります。そうしないと、Java JDBC がスローしてエラーになります。

ユーザー名とパスワードの 2 つの列を持つテーブル users がある場合、コードは prepareStatement に対して次のようになります。

pstm = conn.prepareStatement("Insert Into users values ('YourName', 'Password')");
