MySQLのちゃんとしたサンプルデータ

概要

試験等をする上でスクリプトでランダムに作成するデータではなく、
ある程度"ちゃんとした"データが欲しい時がある。
実は本家MySQLで無料で公開していてくれる。

取得先

https://dev.mysql.com/doc/index-other.html
Example Databases

スクリーンショット 2018-04-12 18.31.29.png

Gzip/Zipフォーマットで公開している

これをmysqlにimportするだけ

# unzip world.sql.zip 
# mysql -uroot -p  < world.sql

データの中身

世界の国々や、言語について。
あたりさわりないデータが入っている。
