按条件统计每月记录

Question

我有一张桌子，我们称它们为SUMMARYDATA

NIP  NAME   DEPARTMENT       STATUSIN           STATUSOUT               LATECOME
------------------------------------------------------------------------------------------------
A1   ARIA   BB         2020-01-21 08:06:23  2020-01-21 11:58:36         00:06:23

我需要SELECT(DEPARTMENT,MONTH,YEARS,COUNT(LATECOME)) COUNT计算记录Count (where LATECOME > '00:00:01') > 2 。

因为，Aria & Brian 每月LATECOME > 2 ，Belle & Ziya 只有 1 LATECOME ，Chloe 每月只有 2 LATECOME 。 所以，在部门 BB 中只有 1 是 Aria，部门 CC 是 0，因为 Chloe & Ziya <= 2 LATECOME 。

这是样本 output 我的意思是：

DEPARTMENT     MONTH    YEAR       LATECOME
-------------------------------------------
  BB            01      2020           2              
  CC            01      2020           0

Answer 1

Create table #SUMMARYDATA(NIP varchar(10), NAME varchar(50),DEPARTMENT varchar(90),STATUSIN datetime, STATUSOUT datetime,LATECOME TIME(0))
Insert into #SUMMARYDATA
Values('A1','ARIA','BB','2020-01-21 08:06:23','2020-01-21 11:58:36','00:06:23'),             
('A1','ARIA','BB','2020-01-22 07:34:27','2020-01-22 17:19:47','00:00:00'),               
('A1','ARIA','BB','2020-01-23 08:30:00','2020-01-23 11:00:00','00:30:00'),

('A2','BELLE','BB','2020-01-22 07:34:27','2020-01-22 17:19:47','00:00:00'),

('A3','CHLOE','CC','2020-01-22 07:34:27','2020-01-22 17:00:44','00:00:00'),

('A4','ZIYA','CC','2020-01-21 07:06:20','2020-01-21 13:58:31','00:00:00'),             
('A4','ZIYA','CC','2020-01-22 07:34:27','2020-01-22 17:19:47','00:00:00'),

('A4','ZIYA','CC','2020-01-24 09:06:00','2020-01-23 15:30:00','02:06:00')


Select s.DEPARTMENT,Q.[Month],Q.[Year], 
    Case when Max(LateCount) > 2 then 1 Else 0 End as LateCome  
from #SUMMARYDATA s 
inner join 
(
 SELECT NAME, MONTH(StatusIn) as [Month] , YEAR(StatusIn) as [Year], 
 Sum(Case when LateCome > '00:00:00' then 1 Else 0 End) as LateCount 
 from #SUMMARYDATA
 group by NAME,  MONTH(StatusIn), YEAR(StatusIn)
) Q 
ON MONTH(s.StatusIn) = Q.[Month] and YEAR(s.StatusIn) =Q.[Year] and s.NAME = q.NAME
group by  s.DEPARTMENT,Q.[Month],Q.[Year]

--- 或者让它更优雅一点

;With sdCTE as
(
 SELECT NAME, DEPARTMENT, MONTH(StatusIn) as [Month] , YEAR(StatusIn) as [Year],  
 Case when LateCome > '00:00:00' then 1 Else 0 End as LateCome 
 from #SUMMARYDATA
)
Select DEPARTMENT, [Month],[Year], 
    Case when Max(LateCount) > 2 then 1 Else 0 End as LateCome  
from
(
    select Name, DEPARTMENT, [Month],[Year], Sum(LateCome) LateCount  
    from sdCTE
    group by Name,DEPARTMENT, [Month],[Year]
) Q
Group by DEPARTMENT, [Month],[Year]

Answer 2

尝试以下操作：

;WITH cte AS 
(
    SELECT DISTINCT [NAME], DEPARTMENT, MONTH(STATUSIN) [MONTH], YEAR(STATUSIN) [YEAR], 
        SUM(CASE WHEN LATECOME = '00:00:00' THEN 0 ELSE 1 END) OVER(PARTITION BY [NAME], DEPARTMENT, MONTH(STATUSIN), YEAR(STATUSIN) ORDER BY [NAME]) Total
    FROM SUMMARYDATA
)

SELECT DEPARTMENT, [MONTH], [YEAR], SUM(CASE WHEN TOTAL > 2 THEN 1 ELSE 0 END) LATECOME
FROM cte
GROUP BY DEPARTMENT, [MONTH], [YEAR]

Answer 3

这是针对更改的要求

;With sdCTE as
(
 SELECT NAME, DEPARTMENT, MONTH(StatusIn) as [Month] , YEAR(StatusIn) as [Year],  
 Case when LateCome > '00:00:00' then 1 Else 0 End as LateCome 
 from #SUMMARYDATA
)

Select DEPARTMENT, [Month],[Year], 
    Sum(Case when (LateCount) > 2 then 1 Else 0 End) as LateCome  
from
(
    select Name, DEPARTMENT, [Month],[Year], Sum(LateCome) LateCount  
    from sdCTE
    group by Name,DEPARTMENT, [Month],[Year]
) Q
Group by DEPARTMENT, [Month],[Year]
