Hitung Hari Hadir dan absen dari tabel

Anda dapat mencoba kueri di bawah ini:

SELECT e.comp_mkey, e.status,   e.resig_date,   dt_of_leave,    e.emp_name,
   e.date_of_joining,  e.emp_card_no,   a.pl_days,    pl_days_opening,    a.month1,
   a.month2,   a.month3,   a.month4,   a.month5,   a.month6,   a.month7,   a.month8,
   a.month9,   a.month10,   a.month11,   a.month12,       
   a.month1 + a.month2 + a.month3 + a.month4 + a.month5 + a.month6 +   a.month7 + a.month8 + a.month9 + +a.month10 + a.month11 + a.month12 AS pl_sum,
   m.[DaysAbsent],m.[DaysPresent]
  FROM p_leave_allocation AS a
   INNER JOIN
   emp_mst AS e
   ON a.emp_card_no = e.emp_card_no
   INNER JOIN
   (
   SELECT 
        comp_mkey,emp_mkey,[month],[year], 
        SUM(CASE WHEN data ='AB' THEN 1 ELSE 0 END) AS [DaysAbsent],
        SUM(CASE WHEN data ='P' THEN 1 ELSE 0 END) AS [DaysPresent]
    FROM
        (
        SELECT comp_mkey,emp_mkey,[month],[year],[Day1],[Day2],[Day3],[Day4],[Day5]
        --,...  
        FROM Emp_mon_day
        ) source
        UNPIVOT
        (
        data FOR day IN ([Day1],[Day2],[Day3],[Day4],[Day5]) -- dynamic query can generate all days data
        )up
        GROUP BY comp_mkey, emp_mkey,[month],[year]
   ) AS m
   ON m.comp_mkey=e.Comp_mkey and m.emp_mkey=e.mkey
   --- ABOVE CRITERIA NEEDS TO BE CHECKED
  WHERE  a.year = 2016
   AND (datediff(MONTH, e.date_of_joining, CONVERT (DATETIME, getdate(), 103)) >= 6
        AND datediff(MONTH, e.date_of_joining, CONVERT (DATETIME, getdate(), 103)) <= 36)
   AND (e.resig_date IS NULL
        OR (e.dt_of_leave IS NOT NULL
            AND e.dt_of_leave >= CONVERT (DATETIME, getdate(), 103)))
   AND e.status IN ('A', 'S')
   AND e.comp_mkey IN (7, 110)
   AND a.Year = 2016;

Penjelasan:

Kami telah menambahkan INNER JOIN lain ke kueri yang ada untuk mendapatkan data yang dikumpulkan dari DaysPresent dan DaysAbsent

Untuk mengoptimalkan ini lebih lanjut, saya sarankan Anda langsung melamar mengikuti WHERE klausa ke source atur

WHERE  comp_mkey IN (7, 110) AND Year = 2016;
