使用 Eloquent 时字段列表中的列“id”不明确

Question

Does anyone know why the following is resulting in a Column 'id' in field list is ambiguous error?

$app_subj_current = \DB::table('tbl_subject')
        ->join('tbl_application', 'tbl_subject.id', '=', 'tbl_application.app_subj_id')
        ->where('tbl_application.id', $application)
        ->lists('tbl_subject.subj_type', 'tbl_subject.id');

I've specified the table for which ID I'm referring to so I cannot understand why I'm getting this error.

Answer 1

I've figured out that the following fixes the problem:

$app_subj_current = \DB::table('tbl_subject')
    ->join('tbl_application', 'tbl_subject.id', '=', 'tbl_application.app_subj_id')
    ->where('tbl_application.id', $application)
    ->select('tbl_subject.subj_type as x', 'tbl_subject.id as y')
    ->lists('x', 'y');

Answer 2

use select() instead of lists() . hope it work.
