foreign keyを貼られる側のテーブルのキーと貼る側のテーブルでキーの書く順番をあわせないといけなかったようです

FOREIGN KEY(member_id, service) REFERENCES other_users(member_id, service) とすればいけたそうです。

わざわざありがとうございました。 言われてみれば確かにそうでしたね。 時間があるときに動かしてみます。 2018年9月18日(火) 11:14 Daisuke Komazaki <[email protected]>:

この辺ですかね

InnoDB permits a foreign key to reference any column or group of columns. However, in the referenced table, there must be an index where the referenced columns are listed as the first columns in the same order. 

InnoDBの場合は順番を守らないといけないみたいです
