Answer 1

试试这个

DB::table('id_master AS t1')
    ->select(DB::raw('
        t2.id,
        name,
        count(*) AS toroku,
        SUM(CASE WHEN tion_flg <> 0 THEN 1 ELSE 0 END ) AS riyou,
        t2.upload_at'))
    ->leftJoin('id_upload AS t2', 't1.upload_id', '=', 't2.upload_id')
    ->groupBy('t2.id','t2.name','t2.upload_at')
    ->orderBy('id')
->get();
