java - java无法向sql数据库写入数据但读取成功

Question

我正在使用下面的代码:

JButton btnEdit = new JButton("Edit");
btnEdit.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        try{
        String query = "Insert Into check(Name, Password)Values(?,?)";
        PreparedStatement pst = con.prepareStatement(query);
        pst.setString(1, textField.getText());
        pst.setString(2, textField_1.getText());
/*      pst.setString(3, textField_2.getText());
        pst.setString(4, textField_4.getText());
        pst.setString(5, textField_5.getText());
        */

        pst.execute();
        JOptionPane.showMessageDialog(null, "Data Saved");
        pst.close();
        }catch(Exception e){
            e.printStackTrace();
        }
    }
});

我正在从 SQL 数据库检索数据，但每当我尝试插入数据时，我都会在运行时收到错误:

Answer 1

“check”是保留关键字，因此代码失败，尝试使用不是关键字的名称应该可以解决问题。
