新建学生信息数据库
1.添加记录模块
<%@ page contentType="text/html" pageEncoding="UTF-8"%><html> <head> <title>添加新学生</title> </head> <body> <form action="stuinsert2.jsp" method="post"> <table border="0" width="238" heigth="252"> <tr><td>学号：</td><td><input type="text" name="id"></td></tr> <tr><td>姓名</td><td><input type="text" name="name"></td></tr> <tr><td>性别</td><td><input type="text" name="sex"></td></tr> <tr><td>年龄</td><td><input type="text" name="age"></td></tr> <tr><td>专业</td><td><input type="text" name="sdept"></td></tr> <tr align="center"> <td colspan="2"> <input type="submit" value="提交">
<input type="reset" value="取消"> </td> </tr> </table> </form> </body></html>
<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8"%><html> <head> <title>添加学生处理程序</title> </head> <body> <% Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url="jdbc:sqlserver://localhost:1433;
DatabaseName=p";
String user="sa";
String password="123456";
Connection conn=DriverManager.getConnection(url,user,password);
request.setCharacterEncoding("UTF-8");
String id=request.getParameter("id");

String sex=request.getParameter("sex");
int age=Integer.parseInt(request.getParameter("age"));
String sdept=request.getParameter("sdept");
String sql=String.format("select * from student where Sno=%s",id);
Statement stmt=conn.createStatement();
PreparedStatement pstmt;
ResultSet rs=stmt.executeQuery(sql);
if(!(rs.next())){

pstmt.setString(1,id);
pstmt.setString(2,name);
pstmt.setString(3,sex);
pstmt.setInt(4,age);
pstmt.setString(5,sdept);
pstmt.executeUpdate();
out.print("添加成功");
%> <a href="stuinsert.jsp" rel="external nofollow" rel="external nofollow" >返回菜单</a><br> <a href="main.jsp" rel="external nofollow" ></a> <%}
else{
out.println("该学号已存在");
%> <a href="stuinsert.jsp" rel="external nofollow" rel="external nofollow" >重新添加</a> <%}

%> <table border="2" bgcolor="ccceee" width="650"> <tr bgcolor="CCCCCC" align="center"> <td>记录条数</td><td>学号</td><td>姓名</td> <td>性别</td><td>年龄</td><td>专业</td> </tr> <% while(rs.next()){
%> <tr align="center"> <td><%=rs.getRow()%></td> <td><%=rs.getString(1)%></td> <td><%=rs.getString(2)%></td> <td><%=rs.getString(3)%></td> <td><%=rs.getString(4)%></td> <td><%=rs.getString(5)%></td> </tr> <%}
%> </center> <%if(rs!=null){
