5. update 示例2：
<%@ page contentType="text/html;charset=gb2312" %> <%@ page import="java.sql.*" %> <% String name=request.getParameter("name"); String age=request.getParameter("age"); String birth=request.getParameter("birth"); String id1=request.getParameter("id1"); System.out.println(id1); Connection con=null; try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; sql=con.createStatement(); String sql2="update student set,age='"+age+"',birth='"+birth+"' wherehttps://www.jb51.net/chakan.jsp">查看</a>
6. insert 插入
<%@ page contentType="text/html;charset=gb2312" %> <%@ page import="java.sql.*" %> <% String name=request.getParameter("name"); String age=request.getParameter("age"); String birth=request.getParameter("birth"); Connection con=null; try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; sql=con.createStatement(); String sql2="insert into student(name,age,birth) values('"+name+"','"+age+"','"+birth+"')"; System.out.print(sql2); int s=sql.executeUpdate(sql2); } catch(Exception e){ System.out.println(e); } %> 恭喜你，添加成功！<br /> <a href="https://www.jb51.net/chakan.jsp">查看</a>
