这是我的java文件，对应于错误，

JAva 文件：

    int price=Integer.parseInt(jTextField3.getText());
    int num=Integer.parseInt(jTextField2.getText());
    int amt=price*num;
    jLabel4.setText(""+amt);


    try {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        con=DriverManager.getConnection("jdbc:odbc:yum");
        String sql="insert into Table1 values(?,?,?)";
        p=con.prepareStatement(sql);
        p.setInt(1,num);
        p.setInt(2,price);
        p.setInt(3,amt);
       p.executeUpdate();

    }
    catch(SQLException | ClassNotFoundException s){
    Logger.getLogger(godGUI.class.getName()).log(Level.SEVERE, null, s);

    }
    finally{
        try {
            p.close();
            con.close();
        } catch (SQLException ex) {
            Logger.getLogger(godGUI.class.getName()).log(Level.SEVERE, null, ex);
        }
    }


}                             

当我为第一个 tym 运行此文件时，它可以工作，但下一个 tym 总是弹出相同的错误。

我已经参考了以前的答案来更改dsn，重新创建文件，关闭finally块中的连接，但仍然出现错误。

我错过了什么吗？

有什么问题可以帮忙吗？

Answer 1

当您使用以下语法进行不带列名的插入查询时

String sql="insert into Table1 values(?,?,?)";

您必须确保提供表中的每个列值，即使是可为空的值。而且您还必须确保按照数据库中定义的确切顺序提供它们。

或使用如下语法。 String sql="insert into Table1 (num, price, amt) values(?,?,?)";

请分享数据库表以获得更多说明。
