语法错误Insert Into语句java

Question

我想在我的MS Acces数据库中添加一个数据集。但我总是在executeUpdate语句的SQL语句中出现语法错误。如果有人能帮助我，那就太好了。

在这里你可以看到错误：

这是错误所基于的代码。它在executeUpdate（）-语句中：

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();
    }

我找不到语法错误！有人能帮我吗？

感谢

Answer 1

电子邮件列中有一个连字符，您应该对其进行转义。有关如何执行此操作，请参阅以下答案：在访问数据库表中的字段名中使用短划线

Answer 2

您需要添加表中所有列的值，否则javaJDBC将抛出并出错。

如果您有一个包含2列用户名和密码的表用户，那么您的prepareStatement代码如下所示。

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