データベース テーブルサイズ一覧

Posted at

データベース内にある各テーブルのサイズをチェック!

頻繁に使わないのでいざ使うときに毎回調べてたのをメモメモ

SELECT 
	table_name,
	floor((data_length+index_length) / (1024 * 1024)) AS table_size,
    floor(data_length / (1024 * 1024)) AS table_data_size,
    floor(index_length / (1024 * 1024)) AS table_index_size ,
    table_rows,
    avg_row_length
FROM information_schema.tables 
WHERE table_schema = database() 
ORDER BY table_size DESC;

余談

確認すると想定とは違うことが偶にある
まさか通知メールのテーブルがが全体の2/3を占めるほど大きかったとは、、、
バックアップ無駄なので退避DB作って一定期間過ぎたらそっちに移動しよう
