可以讲一讲为什么后台的首页sql全都是错了的么

三条sql

        // 会员订单总数和订单总购物额
        // $order = OrderModel::field("COUNT(*) AS order_num,order_amount")->where("status",5)->find();
        $order = OrderModel::fieldRaw("COUNT(*) AS order_num,SUM(order_amount) AS order_amount")->where("status", 5)->find();
        // $usersGoodsCount = OrderModel::withJoin("users")->field("COUNT(DISTINCT order.user_id) as count")->where("order.status",5)->find();
        $usersGoodsCount = OrderModel::field('user_id')->distinct("user_id")->where("status", 5)->count();
        // 订单排行
        // $orderHot = OrderModel::withJoin("users")->field("SUM(order.order_amount) as total,COUNT(order.id) as count,users.username")->where("order.status",5)->group("order.user_id")->order("total","DESC")->limit(10)->select()->toArray();
        $orderHot = OrderModel::
            hasWhere(
                'users',
                ["Order.status" => 5],
                'Users.username,SUM(Order.order_amount) as total,COUNT(Order.id) as count'
            )
            ->group('Order.user_id')->order("total", "DESC")->limit(10)->select()->toArray();

        foreach ($orderHot as $k => $v) {
            $orderHot[$k]['p'] = $k + 1;
        }

        // $data = OrderModel::field('SUM(order_amount) as amount,count(*) as total,create_time,FROM_UNIXTIME(create_time,"%Y%m%d") as days')
        //     ->where("status", "in", "2,5")
        //     ->group('days having create_time >= ' . strtotime(date('Y-m-d 00:00:00', strtotime("-30 day"))) . ' and create_time <= ' . strtotime(date('Y-m-d 23:59:59', time())))->select()->toArray();

        $data = OrderModel::fieldRaw('SUM(order_amount) as amount,count(*) as total,FROM_UNIXTIME(create_time,"%Y%m%d") as days')
            ->where("status", "in", "2,5")
            ->where('create_time >= ' . strtotime(date('Y-m-d 00:00:00', strtotime("-30 day"))))
            ->where('create_time <= ' . strtotime(date('Y-m-d 23:59:59', time())))
            ->group('days')->select()->toArray();

一条return

        // "f"                      => empty($order["order_amount"]) ? "0.00" : number_format(($order["order_amount"] > 0 && $usersGoodsCount["count"] > 0 ? $order["order_amount"] / $usersGoodsCount["count"] : 0), 2),
        "f"                      => empty($order["order_amount"]) ? "0.00" : number_format(($order["order_amount"] > 0 && $usersGoodsCount > 0 ? $order["order_amount"] / $usersGoodsCount : 0), 2),
