这是我的 java 文件，它对应于错误，

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 总是会弹出相同的错误。

我已经引用了之前的答案来更改dsn，重新创建文件，关闭finally block 中的连接，但仍然出现错误。

我在这里遗漏了什么吗？

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="插入表1值(?,?,?)";

您必须确保提供表中的每个列值，甚至是可为空的列值。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="插入Table1(num,price,amt)values(?,?,?)";

请分享数据库表以获取更多说明。
