Count summary records per month with conditional SQL

Question

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

NIP  NAME   DEPARTMENT       STATUSIN           STATUSOUT             TOTALLOSTTIME 
------------         


        

Answer 1

You are mainly just missing a WHERE clause:

SELECT
    DEPARTMENT,
    MONTH(STATUSIN) AS MONTH,
    YEAR(STATUSIN) AS YEAR,
    SUM(DATEDIFF(second, '00:00:00', TOTALLOSTTIME)) AS sum_lost_time_in_sec
FROM SUMMARYDATA
WHERE
    TOTALLOSTIME > '02:00:00'
GROUP BY
    DEPARTMENT,
    MONTH(STATUSIN),
    YEAR(STATUSIN);
