我有一个下面的查询，我运行它为我提供了前一周的单次计数，即Week 44. 截至目前，本周是 45 周。

with data_holder as
(
with tree_post as
(Select contractid as conid, max(goldennmber) as goldennmber
from zeus.user_keys_post group by contractid)
Select * from tree_post join zeus.user_keys_post b
on tree_post.conid = b.contractid and tree_post.goldennmber = b.goldennmber
),
 
name as 
(
SELECT abc, client_id, services from dim.crom c1 where c1.ver = (SELECT MAX(ver) from dim.crom c2 
where c1.client_id = c2.client_id)
)
 
select
count(distinct(clientid))
from data_holder
left join name
on name.client_id = data_holder.clientid
where POC NOT IN ('SGH', 'IKU')
and status IN ('NOTTAKEN')
and (fromWeek <= '44' AND toWeek >= '45')

截至目前，我看到的输出是第 44 周的输出-

Count
-----
124

现在我正在尝试使这个查询动态化，以便它可以让我计算过去 6 周从 44 到 39 不包括当前周的输出，如下所示：

Count   Week
------------
124     W44
125     W43
126     W42
127     W41
128     W40
129     W39

因此，如果我每周手动运行它，我每周的情况都会是这样 -

and (fromWeek <= '44' AND toWeek >= '45') // for week 44
and (fromWeek <= '43' AND toWeek >= '44') // for week 43
and (fromWeek <= '42' AND toWeek >= '43') // for week 42
and (fromWeek <= '41' AND toWeek >= '42') // for week 41
and (fromWeek <= '40' AND toWeek >= '41') // for week 40
and (fromWeek <= '39' AND toWeek >= '40') // for week 39

现在我需要以动态的方式每周进行上述手动查询。我想出了下面的查询，但不知何故，当我运行它时我没有得到任何输出。我在下面的查询中做错了什么？

with data_holder as
(
with tree_post as
(Select contractid as conid, max(goldennmber) as goldennmber
from zeus.user_keys_post group by contractid)
Select * from tree_post join zeus.user_keys_post b
on tree_post.conid = b.contractid and tree_post.goldennmber = b.goldennmber
),
 
name as 
(
SELECT abc, client_id, services from dim.crom c1 where c1.ver = (SELECT MAX(ver) from dim.crom c2 
where c1.client_id = c2.client_id)
)

select fromWeek,
count(distinct(clientid))
from data_holder
left join name
on name.client_id = data_holder.clientid
where POC NOT IN ('SGH', 'IKU')
and status IN ('NOTTAKEN')
and fromWeek <= date_part(w, current_date - interval '6 weeks') 
and toWeek >= date_part(w, current_date)
group by fromWeek

笔记：

fromWeek和toWeek列是整数数据类型，它们包含周数仅供参考。这是一个遗留查询，所以我试图让它动态化。不知道为什么他们在 44 和 45 左右有单引号，但如果我在第 44 周像这样and (fromWeek <= '44' AND toWeek >= '45')或这样运行我的原始手动查询and (fromWeek <= 44 AND toWeek >= 45)，我总是得到与 124 相同的数据。

你不想让 toWeek 比 fromWeek 大 1 吗？如果是这样，您的 where 子句应该是：

...
and fromWeek <= date_part(w, current_date - interval '6 weeks') 
and toWeek >= date_part(w, current_date - interval '5 weeks')
...

我怀疑您只是没有足够高的 toWeek 值数据来传递您的 toWeek where 子句。
