エラー：SQLSTATE [42S22]：カラム見つかりません：1054

Question

私は私の焼いたテーブル（WampServer MySQLデータベース）を実行し、私はこのエラーを取得する：

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Users.user_id' in 'on clause'

If you are using SQL keywords as table column names, you can enable identifier quoting for your database connection in config/app.php.

SQLクエリ：

SELECT `Bookmarks`.`id` AS `Bookmarks__id`, 
     `Bookmarks`.`user_id` AS `Bookmarks__user_id`, 
     `Bookmarks`.`title` AS `Bookmarks__title`, 
     `Bookmarks`.`description` AS `Bookmarks__description`, 
     `Bookmarks`.`url` AS `Bookmarks__url`, 
     `Bookmarks`.`created` AS `Bookmarks__created`, 
     `Bookmarks`.`modified` AS `Bookmarks__modified`, 
     `Users`.`id` AS `Users__id`, 
     `Users`.`email` AS `Users__email`, 
     `Users`.`password` AS `Users__password`, 
     `Users`.`created` AS `Users__created`, 
     `Users`.`modified` AS `Users__modified` 
FROM `bookmarks` `Bookmarks` 
    INNER JOIN `users` `Users` ON 
      `Users`.`user_id` = (`Bookmarks`.`user_id`) 
LIMIT 20 OFFSET 0 

このエラーメッセージをカスタマイズする場合は、src\Template\Error\pdo_error.ctpを作成してください。

ユーザテーブルでは、プライマリIDはidではなく、user_idです。それがエラーを起こす理由です。代わりに、このクエリをお試しください：

SELECT `Bookmarks`.`id` AS `Bookmarks__id`, 
     `Bookmarks`.`user_id` AS `Bookmarks__user_id`, 
     `Bookmarks`.`title` AS `Bookmarks__title`, 
     `Bookmarks`.`description` AS `Bookmarks__description`, 
     `Bookmarks`.`url` AS `Bookmarks__url`, 
     `Bookmarks`.`created` AS `Bookmarks__created`, 
     `Bookmarks`.`modified` AS `Bookmarks__modified`, 
     `Users`.`id` AS `Users__id`, 
     `Users`.`email` AS `Users__email`, 
     `Users`.`password` AS `Users__password`, 
     `Users`.`created` AS `Users__created`, 
     `Users`.`modified` AS `Users__modified` 
FROM `bookmarks` `Bookmarks` 
    INNER JOIN `users` `Users` ON 
      `Users`.`id` = `Bookmarks`.`user_id` 
LIMIT 20 OFFSET 0
