sql加入计数

Question

我有这个声明返回2个不同的计数，我想加入这些计数关于这个月。下面是我目前的说法，我知道我的问题是COUNT（SecondColl。*）作为第二张表的STRAFT。我可以做这样的事吗？

WITH cte as(
    SELECT * FROM K1 
    UNION ALL 
    SELECT * FROM K2 
    UNION ALL 
    SELECT * FROM K3 
    UNION ALL 
    SELECT * FROM K4 
), FirstColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
      from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'STR' 
), SecondColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
      from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'NCD' 
) 
SELECT MONTH(ED) as STRMnth, COUNT(*) as STRRFT , COUNT(SecondColl.*) as STRAFT 
FROM FirstColl 
inner join SecondColl where MONTH(ED) = SecondColl.MONTH(ED) 
group by MONTH(ED) 
order by STRMnth asc

试试这个：

WITH cte as(
    SELECT * FROM K1 
    UNION ALL 
    SELECT * FROM K2 
    UNION ALL 
    SELECT * FROM K3 
    UNION ALL 
    SELECT * FROM K4 
), FirstColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
      from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'STR' 
), SecondColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
      from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'NCD' 
) 
select 
    a.STRMnth, a.cnt1 as STRRFT, b.cnt2 as STRAFT 
from 
    (select month(ED) as STRMnth, count(*) as cnt1 from FirstColl group by month(ED)) a 
    left join 
    (select month(ED) as STRMnth, count(*) as cnt2 from SecondColl group by month(ED)) b 
     on a.STRMnth = b.STRMnth 
order by a.STRMnth asc 

UPDATE1：

WITH cte as(
     SELECT * FROM K1 
     UNION ALL 
     SELECT * FROM K2 
     UNION ALL 
     SELECT * FROM K3 
     UNION ALL 
     SELECT * FROM K4 
    ), FirstColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
       from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'STR' 
    ), SecondColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
       from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'NCD' 
    ), ThirdColl as (SELECT Distinct ED, DP, RN FROM cte WHERE DT = 'STR') 
    select 
     a.STRMnth, a.cnt1 as STRRFT, b.cnt2 as STRAFT 
    from 
     (select month(ED) as STRMnth, count(*) as cnt1 from FirstColl group by month(ED)) a 
     left join 
     (select month(ED) as STRMnth, count(*) as cnt2 from SecondColl group by month(ED)) b 
      on a.STRMnth = b.STRMnth 
     left join 
     (select month(ED) as STRMnth, count(*) as cnt3 from ThirdColl group by month(ED)) c 
      on a.STRMnth = c.STRMnth 
    order by a.STRMnth asc

    ), FirstColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
       from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'STR' 
    ), SecondColl as (SELECT * FROM (Select DP, RN, ET, ED, DT, COUNT(*)OVER(PARTITION BY DP, RN) AS your_count 
       from cte) a WHERE your_count = 1 and ET = 'Complete' and DT = 'NCD' 
    ), ThirdColl as (SELECT distinct ED, DP, RN FROM K1 WHERE Defect_Type = 'STR') 
    select 
     a.STRMnth, a.cnt1 as STRRFT, b.cnt2 as STRAFT 
    from 
     (select month(ED) as STRMnth, count(*) as cnt1 from FirstColl group by month(ED)) a 
     left join 
     (select month(ED) as STRMnth, count(*) as cnt2 from SecondColl group by month(ED)) b

     left join 
     (select month(ED) as STRMnth, count(*) as cnt3 from ThirdColl group by month(ED)) c 
      on a.STRMnth = c.STRMnth 
    order by a.STRMnth asc
