【Laravel】LaravelでDISTINCTを使用する、かつ実行されているSQLを確認してみる

Last updated at Posted at 2018-10-05

LaravelでDISTINCTを使用する

例としてあるユーザーのチームIDの重複を消したい場合

self::where('user_id', $user_id)->distinct()->select('team_id')->get();

self ・・・ 自身のModelを指す(テーブル名はtablesとする)

SQLはどうなってるの

以下のようにtoSql()関数で実行されるSQLを吐き出すことができる

var_dump(self::where('user_id', $user_id)->distinct()->select('team_id')->toSql());

var_dump出力

select distinct `team_id` from `tables` where `user_id` = ?

おわり

  • SQL見ることなんてあんまりないけど、どんなSQL実行されてるのかきになるよね
