Question

我正在执行此查询以从不同的表中获取详细信息。如果用户存在于表上，则要打印行值，否则打印空格。但是没有正确输出。

 $users = DB::table('user_form_submission')
            ->join('recommend_email_send_by_cron', 'recommend_email_send_by_cron.user_id','=','user_form_submission.id')
            ->select('recommend_email_send_by_cron.business_id as businessId',
                'recommend_email_send_by_cron.email as email',
                'user_form_submission.id as userId',
                'recommend_email_send_by_cron.name as name',
                'recommend_email_send_by_cron.status as status',
                'recommend_email_send_by_cron.sign_in_data as sign_in_time',
                'recommend_email_send_by_cron.sent_time as mail_sent_time',
                'user_form_submission.created_at as created_at',
                'user_form_submission.form_id as formId',
                DB::raw("(CASE WHEN (select user_id from track_button_events where (recommend_email_send_by_cron.user_id = user_id) && (recommend_email_send_by_cron.business_id = business_id)) THEN 'Yes' ELSE '' END) as noButtonClicked"),
                DB::raw("(CASE WHEN (select user_id from recommend_feedback_details where (recommend_email_send_by_cron.user_id = user_id) && (recommend_email_send_by_cron.business_id = business_id)) THEN recommend_feedback_details.feedback ELSE '' END) as message"),
                DB::raw("(CASE WHEN (select user_id from recommend_yes_button_track where (recommend_email_send_by_cron.user_id = user_id) && (recommend_email_send_by_cron.business_id = business_id)) THEN 'Yes' ELSE '' END) as yesButtonClicked"),
                DB::raw("(CASE WHEN (recommend_email_send_by_cron.status= 'sent') THEN 'Yes' ELSE '' END) as mail_sent"
            )
            ->where('user_form_submission.business_id', '=', $businessId)
            ->get();

        print_r($users)

错误：

'字段列表'中的未知列'recommended_feedback_details.feedback'

在Laravel Raw Query执行期间获取错误
