我有一张桌子，我们叫他们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)) 和COUNT 每月记录Count (where LATECOME > '00:00:01') > 2。

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

这是我的意思的示例输出：

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

【解决方案1】：

尝试以下方法：

;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]

请找到 dbfiddle here。

【讨论】：

sacse 的方式比我的要好得多 :) - 我是老派 :(
@Srinika 每个正确输出的答案都是 gr8 \m/ :)。
你的更简洁
非常感谢您对我的帮助:) 它的工作.. 但是当我使用我的真实数据运行时.. 我在部门 BB 有 2 个人有 LATECOME > 2.. 为什么输出只显示1不是2？ @sacse
请检查我更新的问题以查看示例数据和输出。谢谢:) @sacse

【解决方案2】：

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'),

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]

我做了，假设如果满足迟到条件，您需要 1 或 0。请检查我的新解决方案。

【解决方案3】：

这是为了改变需求

;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]
