问题
i have written this query to show total working time and overtime of an employee on particular date (if he has came). i want if for a particular date person's INtime and OutTime are empty then put 00:00 in his intime, outtime, totalworkingtime, overtime e.g. it's sunday so obviously no InTime and OutTime then it should show 00:00 in time columns. Note: dates are only entered if person InTIme is mentioned otherwise no DateVisited.
e.g.
EmplID EmplName ShiftID intime Outtime totalworking overtime dateVisited
0000001 John S001 00:00 00:00 00:00: 00:00 2013-12-01
Query:
with times as (
SELECT t1.EmplID
, t3.EmplName
, min(t1.RecTime) AS InTime
, max(t2.RecTime) AS [TimeOut]
, t4.ShiftId as ShiftID
, t4.StAtdTime as ShStartTime
, t4.EndAtdTime as ShEndTime
, cast(min(t1.RecTime) as datetime) AS InTimeSub
, cast(max(t2.RecTime) as datetime) AS TimeOutSub
, t1.RecDate AS [DateVisited]
FROM AtdRecord t1
INNER JOIN
AtdRecord t2
ON t1.EmplID = t2.EmplID
AND t1.RecDate = t2.RecDate
AND t1.RecTime < t2.RecTime
inner join
HrEmployee t3
ON t3.EmplID = t1.EmplID
inner join AtdShiftSect t4
ON t3.ShiftId = t4.ShiftId
group by
t1.EmplID
, t3.EmplName
, t1.RecDate
, t4.ShiftId
, t4.StAtdTime
, t4.EndAtdTime
)
SELECT
EmplID
,EmplName
,ShiftId As ShiftID
,InTime
,[TimeOut]
,convert(char(5),cast([TimeOutSub] - InTimeSub as time), 108) TotalWorkingTime
,[DateVisited]
,CASE WHEN [InTime] IS NOT NULL AND [TimeOut] IS NOT NULL THEN
CONVERT(char(5),CASE WHEN CAST([TimeOutSub] AS DATETIME) >= ShEndTime And ShiftID = 'S002' Then LEFT(CONVERT(varchar(12), DATEADD(ms, DATEDIFF(ms, CAST(ShEndTime AS DATETIME),CAST([TimeOutSub] AS DATETIME)),0), 108),5)
WHEN CAST([TimeOutSub] AS DATETIME) >= ShEndTime And ShiftID = 'S001' Then LEFT(CONVERT(varchar(12), DATEADD(ms, DATEDIFF(ms, CAST(ShEndTime AS DATETIME), CAST([TimeOutSub] AS DATETIME)),0), 108),5)
ELSE '00:00' END, 108)
ELSE 'ABSENT' END AS OverTime
FROM times order by EmplID, ShiftID, DateVisited

If your problem solely relies on knowing when a date is a workday/holiday/weekend I would recommend using a DataWarehouse solution. Create A table that contains all the holidays/weekends and check against it.
Depending on what Calendar and what other dates you are using there are many scripts out there to create it for you, but the simplest way would be for the next 10 years or so calculate when all your holidays land on. for example Christmas is always on December 23 and thanksgiving is always 3 week in November I would create a table like this
CREATE TABLE Holiday
(
HolidayID INT NOT NULL, --surrogate key, but you can just as easily make HolidayDate the Natural key
HolidayDate DATE NOT NULL
HolidayName NVARCHAR(30),--encase you need non English holiday names saved
...
...
..
INSERT INTO Holiday (HolidayDate,HolidayName) VALUES (2014-12-23, 'Christmas')
INSERT INTO Holiday (HolidayDate,HolidayName) VALUES (2015-12-23, 'Christmas')
INSERT INTO Holiday (HolidayDate,HolidayName) VALUES (2016-12-23, 'Christmas')
INSERT INTO Holiday (HolidayDate,HolidayName) VALUES (2017-12-23, 'Christmas')
.....
.....
....
Or if you want to get even more indepth you can map out ever day for the next 10 years in a table (Date Dimension table). Then mark those days as holidays, work cancelled, sales quarters and what not. (google Date Dimension Table)
