    Thumbs up Re: Moving MySql Database from one machine to another machine

    Hello vaishali,

    Try this code:

    import java.io.*;
     
    public class sqlBackup {
     
        public static void main(String[] args) {
     
            //Location of the backup
            File test = new File("C:/mysql-5.0.27-win32/bin/backup.sql");
     
            FileWriter fw = null;
     
            try {
            fw = new FileWriter(test);
            Runtime rt = Runtime.getRuntime();
     
            //start output backup - change bjse to db name
            Process child = rt.exec("mysqldump -u root bjse");
            InputStream in = child.getInputStream();
     
            InputStreamReader xx = new InputStreamReader(in, "utf8");
            char[] chars = new char[1];     
            int ibyte = 0;
     
            while ((ibyte = xx.read(chars)) > 0) {
            fw.write(chars);
            }
            fw.close();
     
            System.out.println("OK! Completed");
     
            }catch(Exception e)
            {
            e.printStackTrace();
            } 
     
        }
    }

    You can use the mysql command mysqldump to copy contents of your database from the command prompt.

    I know its not java code but if you do it programatically you will first have to install java etc...

    Mysqldump –u root –all-databases > tmp.sql will save it to a folder where you can then use the reverse:

    Mysqldump –u root –all-databases < tmp.sql to pull it back in on the new machine.

    Hope it helps...

    Thanks for your input tpjava.

    I think the code I submitted above does something similar using mysqldump.

    Hi Vaishaly,
    Simply you go to Mysql administrater window. Then click on Backup. It will ask for project name. After giving project name you will can add backup to a file. then when you want to restore, goto restore button and restore it. Try it..............
