MySqldump

Hi friends,

If you find Mysqldump on google you will find lots of website to create dump file, backup file from existing one or more databases of mysql and restore it.

Best link is,

http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html

I want to just write a little bit thing that I searched lot.

That when we generate dump - sql - backup file from mysql, uses command

shell>> mysqldump -u uname -p dbname > dbfile.sql

That will back complete database to dbfile.sql

When on reverse, if I tried to restore that database from dbfile.sql

on Windows it works using same mysqldump

c://MySql//bin> mysqldump dbname < dbfile.sql

Just difference of < and >

while the same thing in linux not works
It will purform and shows output as below

-- MySQL dump 10.11

-- Dump completed on 2010-05-01 13:02:48


It says Dump completed but when we goto that perticular database and show tables
It will give 0 tables there in database.
for linux we have to use mysql command

shell>> mysql -u root -p dbname < dffile.sql

That will works well.

but for that required to create database first in mysql.
