Can not issue data manipulation statements with executeQuery().JAVA WEB 求助

    request.setCharacterEncoding("UTF-8");
    String id=request.getParameter("id");
    String name=request.getParameter("name");
    System.out.println(name);
    String age=request.getParameter("age");
    String gender=request.getParameter("gender");
    String major=request.getParameter("major");
    
    Connection conn=null; 
    Statement stmt=null; 
    ResultSet rs=null;
    Class.forName("com.mysql.jdbc.Driver"); 
    String url="jdbc:mysql://localhost:3306/orcl"; 
    String user="root"; 
    String password="root"; 
    conn=DriverManager.getConnection(url,user,password); 
    stmt=conn.createStatement(); 
    rs=stmt.executeQuery("insert into student (id,name,age,gender,major)values("+id+"','"+name+"','"+age+",'"+gender+"','"+major+")");%>
   把executeQuery改成executeUpdate也不行 因为要返回一个ResultSet

  1.   

    你能不能把JSP贴全一点，然后把报错信息也贴全一点，就一行信息，大家都不是神仙，明白？

    这里你用的是executeQuery这个API，但是SQL语句却是insert语句，导致了出错
    如果你像插入数据，返回结果肯定不是ResultSet,你试下下面的JSP可以么<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

    又报错了 ou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''dfg )' at line 1
      

  7.   

    你的数据表student的字段和类型给出来，这个会影响插入的语法是否正确论坛这种速度太慢 519582737 加QQ
      

  8.   

    这是我做实验的student表的创建语句CREATE TABLE `student` (
      `id` bigint(20) NOT NULL AUTO_INCREMENT,
      `NAME` varchar(255) DEFAULT NULL,
      `age` int(11) DEFAULT NULL,
      `gender` varchar(20) DEFAULT NULL,
      `major` varchar(255) DEFAULT NULL,
      PRIMARY KEY (`id`)
    )
    下面是测试可以通过的JSP页面，我的JDBC的URL连接是MSDB数据库，你改成你自己的ORCL就可以了
    还有我只是跑通了一个自己给定的值，你可以改成你其他页面传过来的各种属性，但是id age需要从
    String转化为int类型<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
