MYSQL 全テーブル、データベース(schema)から特定のカラムを検索

このカラムを持つテーブルって何だっけ??って時に使える
information_schemaから取得する方法

SELECT  TABLE_SCHEMA,TABLE_NAME,COLUMN_NAME FROM information_schema.columns WHERE column_name = '特定のカラム名' ;

見やすく複数行で

SELECT
    TABLE_SCHEMA
    ,TABLE_NAME
    ,COLUMN_NAME
FROM
    information_schema.columns
WHERE
    column_name = '特定のカラム名'
;

*補足 WHERE句にスキーマ名(TABLE_SCHEMA)を指定しても良いかも
