Du kan prova frågan nedan:
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
(

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;
Förklaring:
Vi har lagt till ytterligare en INNER JOIN till den befintliga frågan för att få samlad data från DaysPresent och DaysAbsent
För att optimera detta ytterligare, föreslår jag att du ansöker direkt efter WHERE klausul till source ställ in
WHERE comp_mkey IN (7, 110) AND Year = 2016;
