How to generate employee timesheet in sql server - sql-server

Question

I have five tables:
Employees(EmpId, FirstName, LastName, DeptId,…)
Attendance(LogId, PunchIn, PunchOut,...)
Leave(RequestId, StartDate, endDate, LeaveType,...)
Holiday(HolidayId, Descriptions, StartDate, EndDate,....)
Business Travel(Request_Id, RequestDate, StartDate, EndDate,....)
I am trying to generate a monthly/Annual time-sheet report, time-sheet must represent an employee (or group of employees) status at the corresponding date like: on duty, later arrived, leave vacation, sick leave etc.
I create the following function
Create Function dbo.fn_GetEmployeeStatus(#LogDate Date, #BadgeNo int)
Returns char(3)
As
begin
Declare #status char(3) = null;
Declare #punchin DateTime;
Declare #punchout DateTime;
Declare #ShiftId tinyint;
Declare #LateEarly smallint;
Declare #id int = null;
Set #status = null;
Select #ShiftId = Shift_Id From Staff
Where Badge_No = Badge_No;
Select #id = Max(Holiday_Id) From Holiday
Where #LogDate Between StartDate And EndDate
if(#id is not null)
Set #status = 'HOL' --Holiday
else Set #status = null;
if(#status is null)
begin
Set #id = null;
Select #id = Max(Request_Id) From BusinessTravel
Where #LogDate Between Start_Date And End_Date
And Badge_No = #BadgeNo
if(#id is not null)
Set #status = 'BST' --Business Travel
else Set #status = null;
end
if(#status is null)
begin
Set #id = null;
Select #id = Max(LeaveCategory_Id) From Leaves
Where #LogDate Between Start_Date And End_Date
And Badge_No = #BadgeNo
if(#id is not null)
begin
Set #status = Case #id
When 1 Then 'ANV' --Annual Leave
When 2 Then 'SIC' --Sick leave
When 3 Then 'SLV' --Study leave
When 4 Then 'ELV' --Emergency leave
When 5 Then 'ULV' --Unpaid leave
When 6 Then 'HLV' --Haj Leave
When 7 Then 'MLV' --Marriage leave
When 8 Then 'DLV' --Death of a relative
When 9 Then 'PLV' --Paternity leave
When 7 Then 'MLV' --Materinty Leave
else 'UNK' end; --Unknown
end else Set #status = null;
end
if(#status is null)
begin
Select #punchin = Min(Log_Date), #punchout = Max(Log_Date) From AttendanceLog
Where Cast(Log_Date as Date) = #LogDate
And Badge_No = #BadgeNo
if(#punchin is not null)
begin
Select #LateEarly = dbo.fun_GetEarlyLateAmt(#punchin, 1, #ShiftId)
if(#LateEarly > 20)
begin
Select #LateEarly = dbo.fun_GetEarlyLateAmt(#punchout, 0, #ShiftId)
if(#LateEarly > 10)
Set #status = 'L&E'; --Late Arrive & Early left
else Set #status = 'LTE'; --Late Arrive
end else Set #status = 'ODU'; --On Duty
end --else Set #status = null;
end
if(#status is null)
begin
if ((DatePart(dw, #LogDate) + ##DateFirst) % 7) in(0, 6)
Set #status = 'WKE'; --Weekend
Set #status = 'ABS';
end --else Set #status = 'ABS';
Return #status;
end
--But the following failed
Declare
#BadgeNo int = 2523,
#Year int = 2019
;With data as (
Select DateName(month, InTime) Mon, LogInDay = DATEPART(DAY, DATEADD(HOUR, -6, InTime))
,LogYear = DATEPART(YEAR, InTime), LogMonth = DATEPART(MONTH, InTime),
dbo.fn_GetEmployeeStatus_2(InTime, Badge_No) eStatus From v_EmpAttendanceStatus--v_AttendanceLog
Where DATEPART(YEAR, InTime) = #Year
And Badge_No = #BadgeNo)
Select Mon, LogYear, LogMonth, IsNull([1], 0)[1], IsNull([2], 0)[2], IsNull([3], 0)[3], IsNull([4], 0)[4], IsNull([5], 0)[5], IsNull([6], 0)[6], IsNull([7], 0)[7], IsNull([8], 0)[8], IsNull([9], 0)[9], IsNull([10], 0)[10], IsNull([11], 0)[11], IsNull([12], 0)[12], IsNull([13], 0)[13], IsNull([14], 0)[14], IsNull([15], 0)[15], IsNull([16], 0)[16], IsNull([17], 0)[17], IsNull([18], 0)[18], IsNull([19], 0)[19], IsNull([20], 0)[20], IsNull([21], 0)[21], IsNull([22], 0)[22], IsNull([23], 0)[23], IsNull([24], 0)[24], IsNull([25], 0)[25], IsNull([26], 0)[26], IsNull([27], 0)[27], IsNull([28], 0)[28], IsNull([29], 0)[29], IsNull([30], 0)[30], IsNull([31], 0)[31]
From data
Pivot (
Max(eStatus)
For LogInDay In
([1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31])
) as piv
Order By LogMonth
