Laravel cross database query

One 、SQL sentence

Across the database ：env(‘LARGE_DATABASE’)

            $sql = " SELECT b.operator,count(DISTINCT a.id) qty FROM proofing_notice a JOIN proofing_notice_operator b ON a.id = b.notice_id LEFT JOIN deve_color c on a.color_id = c.id LEFT JOIN ". env('LARGE_DATABASE') ."large_color d on a.color_id = d.id WHERE a.id= b.notice_id and a.status = ". $status_for_sql ." AND b.flag = ". $flag_for_sql ." AND a.area_id in (" .$place_from_str.") AND a.deleted_at IS NULL AND c.deleted_at IS NULL AND d.deleted_at is NULL ";
            if ($status_for_sql == 9) {
    
                $sql .= " AND !(a.paper_type_id =0 AND a.delivery_date IS NULL) GROUP BY b.operator";
            }else{
    
                $sql .= " GROUP BY b.operator";
            }
            $nodo = DB::select($sql);

Two 、laravel Model

Across the database LARGE_DATABASE： from(DB::raw(env(“LARGE_DATABASE”)
