谁帮忙把下面的例子改成向数据库中添加一条记录而不是update

下面上传到数据库中的例子是更新一条记录,而不是插入一条新的纪录。
谁有向数据库中插入新的记录的例子 (要求上载的文件也保存到数据库中,感激不尽)
原来的代码是:
<%@ page language="java" import="java.sql.*,com.jspsmart.upload.*"%>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" />
<HTML>
<BODY BGCOLOR="white">
<H1>jspSmartUpload : Sample 4</H1>
<HR>
<%
// Variables
int count=0;
// Connect to the database
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql:///test");
// SQL Request
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("SELECT * FROM TFILES WHERE ID=1");
// if the resultset is not null
if (rs.next()){
// Initialization
mySmartUpload.initialize(pageContext);
// Upload
mySmartUpload.upload();
// upload file in the DB if this file is not missing
if (!mySmartUpload.getFiles().getFile(0).isMissing()){
try {
rs.updateString("FILENAME",mySmartUpload.getFiles().getFile(0).getFileName());
// Add the current file in the DB field
mySmartUpload.getFiles().getFile(0).fileToField(rs,"FILE");
// Update
rs.updateRow();
count++;
} catch(Exception e) {
out.println("An error occurs : " + e.toString());
}
}
}
// Display the number of files uploaded
out.println(count + " file(s) uploaded in the database.");
rs.close();
stmt.close();
con.close();
