Count records per month with condition

Question

I have a table, let\'s call them SUMMARYDATA

NIP  NAME   DEPARTMENT       STATUSIN           STATUSOUT               LATECOME
-----------------------         


        

Answer 1

try the following:

;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]
