我是想做一个什么事呢：就是在jsp里用statement的executeQuery（string）来向数据库增加数据，数据库为hanshuangwu，表为infor，其中只有两个属性：id、name。执行下面的代码后，显示在“****”标记的代码处有“Unknown column 'idString' in 'field list' ”错误，菜鸟求解，请高手不吝赐教啊^_^
<%@page import="javax.servlet.jsp.tagext.TryCatchFinally"%>
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030" import="java.sql.*"%>
<% request.setCharacterEncoding("gb2312"); %>
