DB门面本地正常，为什么到线上Connection.php报错？

public function getCompanyByName($name, $is_related){
    $sql = '
            company_name as name,
            1 as in_target,
            null as grade,
            null as uuid,
            null as province,
            null as city,
            null as country,
            null as area_code,
            null as tel,
            null as subject,
            null as address,
            null as web_site,
            null as union_id
            from erp_company_terminal_list where';

        if ($is_related) {
        //拼接SQL，本地正常，线上报错。也试过以下2种，报同样的错
        //DB::table()->selectRaw()->get()
        //DB::select();
            $sql .= '
            medsci_name = ? ';

            return \DB::query()
                ->selectRaw($sql,[$name])
                ->limit(1)
                ->get();

        } else {
        //拼接另一条sql，本地和线上都正常
    }
}

本地和线上都是laravel5.5的，报错截图
