Количество записей в месяц с условием на SQL сервере

Question

У меня есть таблица, давайте назовем их 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

Мне нужно SELECT(DEPARTMENT,MONTH,YEARS,COUNT(LATECOME)) и COUNT записей Count (where LATECOME > '00:00:01') > 2 в месяц.

Потому что, Aria & Brian имеет LATECOME > 2 в месяц, Belle & Ziya только 1 LATECOME и Chloe Only 2 LATECOME в месяц. Итак, в Отделе BB только 1, то есть Ария, а в Отделе CC - 0, потому что Chloe & Ziya <= 2 LATECOME.

И это пример вывода, который я имел в виду:

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

Answer 1

попробуйте следующее:

;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] 

Пожалуйста, найдите дб <> fiddle здесь .

Answer 2

Create table #SUMMARYDATA(NIP varchar(10), NAME varchar(50),DEPARTMENT varchar(90),STATUSIN datetime, STATUSOUT datetime,LATECOME TIME(0))
Insert into #SUMMARYDATA
