用户类型是order表中的order_source字段，用户昵称/店铺是通过order的order_source字段判断是用户通过平台下单是店铺在平台下应急订单，
用户昵称是order表通过user_id关联member_users表获取nickname字段为用户名称，
店铺名称是order表通过shop_id关联shop_auth_records并判断shop_id是否存在存在则获取shop_name字段为店铺名称不存在则空着即可，
订单类型是order表中的order_type字段，项目名称是order表的service_id关联shop_services表并判断是否存在service_id存在则获取name为项目名称不存在则空着即可，
订单金额是order表total_amount字段，到店时间是order表id关联order_records表并判断状态state为已到店状态时的created_at字段为到店时间，
订单状态是order表id关联order_records表最新的状态state,
店铺分成、推广分成、平台抽成都是order表id关联wallet_split_records通过该表中的split_type不同的分账类型去参与分成最后split_amount字段就是店铺分成、推广分成、平台抽成最终字段
