Answer 1

The Same thing Can also be done using Switch :)

SELECT EmpAttendance.EmpID, EmpAttendance.Empname, EmpAttendance.EmpSex, EmpAttendance.EmpDepartment, EmpProfileTBL.Salary, 
SUM(SWITCH(EmpAttendance.AttendStatus = 'Present', 1, EmpAttendance.AttendStatus = 'Absent', 0, EmpAttendance.AttendStatus = 'Half-Day', 0)) AS TotalPresent,
SUM(SWITCH(EmpAttendance.AttendStatus = 'Absent', 1, EmpAttendance.AttendStatus = 'Present', 0, EmpAttendance.AttendStatus = 'Half-Day', 0)) AS TotalAbsent,
SUM(SWITCH(EmpAttendance.AttendStatus = 'Half-Day', 1, EmpAttendance.AttendStatus = 'Present', 0, EmpAttendance.AttendStatus = 'Absent', 0)) AS HalfDay,

DatePart('m', EmpAttendance.DateOfAttendance) AS CurMonth,
((EmpProfileTBL.Salary * TotalPresent) - (EmpProfileTBL.Salary * TotalAbsent) 
                         + ((EmpProfileTBL.Salary / 2) * HalfDay)) AS FinalSalary
FROM ((EmpAttendance INNER JOIN LocalVariableTable
ON EmpAttendance.EmpDepartment = LocalVariableTable.TempDepartment AND
DatePart('m', EmpAttendance.DateOfAttendance) = LocalVariableTable.TempMonth
 AND DatePart('yyyy', EmpAttendance.DateOfAttendance) = LocalVariableTable.TempYear)
INNER JOIN
EmpProfileTBL ON EmpAttendance.EmpID = EmpProfileTBL.EmpID)

GROUP BY EmpAttendance.EmpID, EmpAttendance.Empname, EmpAttendance.EmpSex,
EmpAttendance.EmpDepartment, DatePart('m', EmpAttendance.DateOfAttendance), 
EmpProfileTBL.Salary
ORDER BY DatePart('m', EmpAttendance.DateOfAttendance) DESC
