BackUp MySql Database from CommandLine

Question

I am able to backup mysql database via command line by executing the below :

C:\MySQL\MySQL Server 5.0\bin\mysqldump\" -uroot -ppassword sample > \"D:/admindb/AAR12.sql\"

But there is no DROP and CREATE database queries in my .mysql file

What should i add in the syntax to get the create info to my generated .sql file ?

    -- MySQL dump 10.11
--
-- Host: localhost    Database: sample
-- ------------------------------------------------------
-- Server version   5.0.67-community-nt

Answer 1

You can use --add-drop-table and --create-options options.

--add-drop-table

Add a DROP TABLE statement before each CREATE TABLE statement.

mysqldump

Actually CREATE TABLE should be added even without any additional keys.

UPDATE:

content of backup.bat

C:\MySQL\MySQL Server 5.0\bin\mysqldump -uroot -ppassword sample >
                                                     D:/admindb/AAR12.sql
copy db_restore.sql+AAR12.sql restore.sql

Assuming that you create manually db_restore.sql and put all database-wide create/drop operations. The backup.bat should produce restore.sql with database drop/create and your table data.
