新建学生信息数据库
1.添加记录模块

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">
