Import/Export MySQL databases and other commands

Posted in MySql on June 16th, 2010 by phoenixdigital

Just a quick reminder of how to backup and restore MySQL databases.

nice mysqldump --opt -u [user_name] -p [database_name] | gzip > [backup_file].dump.gz
nice mysqldump --opt -u [user_name] -p [database_name] | 7za a -si database7z 20140306-database.dump.7z

To restore

nice gzip -d [backup_file].dump.gz
nice mysql [database_name] < [backup_file].dump

To create a database

mysql -u root -p
create database [the_database_name]

To change the database
use [the_database_name];

To show all databases
show databases;

To show indexes on a table

To show all tables
show tables;
show tables like "test1";
