Firstly, create a table 'myfile'in mysql database

CREATE TABLE `myfile` (                      
          `id` bigint(255) NOT NULL auto_increment,  
          `name` varchar(255) default NULL,          
          `file` longblob,                           
          PRIMARY KEY  (`id`)                        
        ) 

<%@page import="java.io.*"%>
<%@page import="java.sql.*"%>

String fileName = "c:/data.csv";

FileInputStream fis = null;
PreparedStatement pstmt = null;
try {
        Class.forName("com.mysql.jdbc.Driver").newInstance();
        Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root" );
File file = new File(fileName);
fis = new FileInputStream(file);
pstmt = conn.prepareStatement("insert into myfile( name, file) values ( ?, ?)");
pstmt.setString(1, file.getName());
pstmt.setAsciiStream(2, fis, (int) file.length());
pstmt.executeUpdate();
pstmt.close();
fis.close();
conn.close();
} 
catch (Exception e) {
System.err.println("Error: " + e.getMessage());
e.printStackTrace();
} 
out.println("Inserted successfully!");
