Question

我正在寻找一种SQL编码，该编码将在某个状态出现时对计数求和，并对该状态的特定行具有该总和。我能够创建两列来总计特定状态的计数，但是每一行中都有这个数字。

例如，如果有24条亚利桑那记录，那么我去了24条记录，在亚利桑那的每一行中都出现。如果俄勒冈州有58条记录，那么我希望58条记录在俄勒冈州的每一行中。等等...

这是我目前拥有的

select appid,  rcvddt,  state,
       sum(count(case when state = 'OR' then 1 else null end)) over () as  ORcount,
       sum(count(case when state = 'AZ' then 1 else null end)) over ()  as AZcount
from smbus.submissions
where (apprcvddt >= '2017-08-01' and apprcvddt <= '2018-08-31')
group by    state,  rcvddt, appid
order by (case when state is null then 1 else 0 end), state

Answer 1

我认为您只想将count()作为窗口函数：

select s.*,
       count(*) over (partition by state) as state_cnt
from smbus.submissions s
where apprcvddt >= '2017-08-01' and apprcvddt <= '2018-08-31'
order by (case when state is null then 1 else 0 end), state

状态等于时的SQL Sum大小写
