有一张运单表：dwd_biz_waybill_td，该表的主键是way_bill_id，并且有如下字段：
way_bill_id（运单表主键），shiping_date（下单日期，时间格式为yyyy-MM-dd），payment_customer_id（付款客户），damaged_degree_type（是否严重破损，为枚举值。1为是，0为否），is_throw_away（是否丢失，为枚举值。1为是，0为否），is_pickup_overtime（是否取超时，为枚举值。1为是，0为否）。需求为：
求连续俩周 严重破损的客户，丢失的客户、取超时的客户。最终结果表的字段：
payment_customer_id，is_serious_damage_tw /*是否【连续2周】严重破损*/，is_serious_damage_tw /*是否【连续2周】丢失*/，is_serious_damage_tw, /*是否【连续2周】取超时*/
注意：这里的连续是指符合要求的周要连续。比如本周符合条件以及上周符合条件。
思路：
方式一：
步骤一：
求每天严重破损、取超时的客户
with v_customer_votes_base_data as (
select
waybill_td.payment_customer_id,
waybill_td.shiping_date,
CASE
when shiping_date>= date_format(date_trunc('week',current_date),'%Y-%m-%d') then 'cur_week'
when cast(date_add('day',-7,cast(date_format(date_trunc('week',current_date),'%Y-%m-%d') as date )) as varchar)<=shiping_date
and shiping_date<cast(date_format(date_trunc('week',current_date),'%Y-%m-%d') as varchar) then 'last_week'
else null
end as shiping_date_week,

and waybill_td.shiping_date<= date_format(current_date,'%Y-%m-%d')
group by waybill_td.payment_customer_id,waybill_td.shiping_date
),第二步，求本周与上周的相关指标
/*客户连续俩周的相关指标*/

sum(payment_order_pickup_overdue_votes) as payment_order_pickup_overdue_votes, /*订单取超时数*/
sum(payment_inner_overdue_votes) as payment_inner_overdue_votes /*内因超时票（内因）*/
from v_customer_votes_base_data
where shiping_date_week is not null
group by payment_customer_id,shiping_date_week

from v_customer_votes_result
group by payment_customer_id
