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 name=request.getParameter("name");  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=conn.prepareStatement("insert into Student values(?,?,?,?,?)");  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>  <%}%> </body></html>

2.查询(all)模块

<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8"%><%@ page import="javax.sql.*" %><%@ page import="javax.naming.*" %><html> <head> <title>信息查看页面</title> </head>  <body> <center> <% DataSource ds=null;  InitialContext ctx=new InitialContext();  ds=(DataSource)ctx.lookup("java:comp/env/jdbc/sqlserver");  Connection conn=ds.getConnection();  PreparedStatement pstmt=conn.prepareStatement("select * from Student");  ResultSet rs=pstmt.executeQuery(); %>    <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){rs.close();}  if(pstmt!=null){pstmt.close();}  if(conn!=null){conn.close();}  %> </table>  </body></html>

条件查询模块

<%@ page language="java" pageEncoding="UTF-8"%><html> <head> <title>My JSP 'stufind2.jsp' starting page</title> </head> <body> 请选择查询条件<hr width="100%" size="3"> <form action="stufind3.jsp" method="post"> 性别<input type="radio" value="男" name="sex" checked="checked">男 <input type="radio" value="女" name="sex">女 年龄范围：<p>   最小：<input type="text" name="a1"><br><br>  最大：<input type="text" name="a2"><p> <input type="submit" value="提交"> <input type="reset" value="取消"> </form> </body></html>

<%@ page contentType="text/html" import="java.sql.*" pageEncoding="UTF-8"%><html> <head> <title>条件查询处理页面</title> </head> <body> <center> <%Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); String user="sa"; String password="123456"; String url="jdbc:sqlserver://localhost:1433;DatabaseName=p"; Connection conn=DriverManager.getConnection(url,user,password); request.setCharacterEncoding("UTF-8"); String sex=request.getParameter("sex"); int age1=Integer.parseInt(request.getParameter("a1")); int age2=Integer.parseInt(request.getParameter("a2")); String sql="select * from Student where Ssex=? and Sage>=? and Sage<=?"; PreparedStatement pstmt=conn.prepareStatement(sql); pstmt.setString(1,sex); pstmt.setInt(2,age1); pstmt.setInt(3,age2); ResultSet rs=pstmt.executeQuery(); %> <table border="2" bgcolor="ccceee" width="650"> <tr bgcolcor="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> <%}%> </table> <%if(rs!=null){rs.close();}  if(pstmt!=null){pstmt.close();}  if(conn!=null){conn.close();} %> </center> </body></html>

3.修改模块

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><html> <head>  <title>修改提交页面</title> </head> <body> <center>  请选择修改记录所满足的条件 <form action="stuupdate2.jsp" method="post">  姓名： <input type="text" name="name"><br><br>  性别： 男<input type="radio" value="男" name="sex">      女<input type="radio" value="女" name="sex"><br><br>  <input type="submit" value="提交">     <input type="reset" value="取消"> </form> </center> </body></html>

<%@ page contentType="text/html" import="java.sql.*" pageEncoding="UTF-8"%><html> <head>  <title>修改编辑页面</title> </head> <body> <% Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");  String user="sa";  String password="123456";  String url="jdbc:sqlserver://localhost:1433;DatabaseName=p";  Connection conn=DriverManager.getConnection(url,user,password);  request.setCharacterEncoding("UTF-8");  String name=request.getParameter("name");  String sex=request.getParameter("sex");  session.setAttribute("sex",sex);  session.setAttribute("name",name);  String sql="select * from Student where Ssex=? and Sname=?";  PreparedStatement pstmt=conn.prepareStatement(sql);  pstmt.setString(1,sex);  pstmt.setString(2,name);  ResultSet rs=pstmt.executeQuery();  if(rs.next()){  String id=rs.getString("Sno");  String name2=rs.getString("Sname");  String sex2=rs.getString("Ssex");  int age=rs.getInt("Sage");  String sdept=rs.getString("Sdept");  if(pstmt!=null){pstmt.close();}  if(rs!=null){rs.close();}  if(conn!=null){conn.close();}  %>  <form action="stuupdate3.jsp" method="post">  <table border="0" width="238" height="252">  <tr><td>学号:</td><td><input type="text" name="id" value=<%=id%>></td></tr>  <tr><td>姓名:</td><td><input type="text" name="name2" value=<%=name2%>></td></tr>  <tr><td>性别:</td><td><input type="text" name="sex2" value=<%=sex2%>></td></tr>  <tr><td>年龄:</td><td><input type="text" name="age" value=<%=age%>></td></tr>  <tr><td>专业:</td><td><input type="text" name="sdept" value=<%=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>  <%}  else{%>      没有找到合适条件的记录！！<%   if(rs!=null){rs.close();}   if(pstmt!=null){pstmt.close();}   if(conn!=null){conn.close();} }%> </body></html>

<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8"%><html> <head>  <title>修改后重写页面</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);  String sql="update Student set Sno=?,Sname=?,Ssex=?,Sage=?,Sdept=? where Sname=? and Ssex=?";  PreparedStatement pstmt=conn.prepareStatement(sql);  request.setCharacterEncoding("UTF-8");  String id=request.getParameter("id");  String name2=request.getParameter("name2");  String sex2=request.getParameter("sex2");  int age=Integer.parseInt(request.getParameter("age"));  String sdept=request.getParameter("sdept");  String name=(String)session.getAttribute("name");  String sex=(String)session.getAttribute("sex");  pstmt.setString(1,id); pstmt.setString(2,name2);  pstmt.setString(3,sex2); pstmt.setInt(4,age);  pstmt.setString(5,sdept); pstmt.setString(6,name);  pstmt.setString(7,sex);  int n=pstmt.executeUpdate();  if(n>=1){%>重写数据库操作成功！<br><%}  else{%>重写数据库操作失败！<br><%}  if(pstmt!=null){pstmt.close();}  if(conn!=null){conn.close();} %> </body></html>

4.删除记录模块

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><html> <head>  <title>条件删除提交页面</title> </head> <body>  请选择删除记录条件<<hr width="100%" size="3">  <form action="studelete2.jsp" method="post">  姓名：<input type="text" name="name"><br><br>  性别：男<input type="radio" value="男" name="sex">  女<input type="radio" value="女" name="sex"><br><br>  年龄范围：<br><p>  最小：<input type="text" name="a1"><br>  最大：<input type="text" name="a2">  </p>  <input type="submit" value="提交">  <input type="reset" value="取消">  </form> </body></html>

<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8"%><html> <head>  <title>条件删除处理页面</title> </head>  <body> <% Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");  String user="sa";  String password="123456";  String url="jdbc:sqlserver://localhost:1433;DatabaseName=p";  Connection conn=DriverManager.getConnection(url,user,password);  request.setCharacterEncoding("UTF-8");  String name=request.getParameter("name");  String sex=request.getParameter("sex");  String ag1=request.getParameter("a1");  String ag2=request.getParameter("a2");  int a3,a4;  String sql="delete from Student where Sname=? and Ssex=? and Sage>=? and Sage<=?";  PreparedStatement pstmt=conn.prepareStatement(sql);  if(!name.equals("")) pstmt.setString(1,name);  if(sex!=null) pstmt.setString(2,sex);  if(!ag1.equals("")){a3=Integer.parseInt(ag1); pstmt.setInt(3,a3);}  if(!ag2.equals("")){a4=Integer.parseInt(ag2); pstmt.setInt(4,a4);}  int n=pstmt.executeUpdate();  if(n==1){%>数据删除成功<br><%}  else{%>数据删除失败！<br><%}  if(pstmt!=null){pstmt.close();}  if(conn!=null){conn.close();} %> </body></html>
