0	It depends on input data. An employee can do more than one in and out ( i.e. for breaks).. Could you please post us back some sample data?

0	Hi, Before you insert every row to the table calculate the difference between intime and outtime and insert the value in Whours column. So, you get the Employee working hours for that particular Row (time) . do this for every row. Best way to insert values by passing first 5 parameters is by using a storedProcedure and mentions working hours logic as mention above in my post create procedure SpDailyWhours ( @empid int, @empname varchar(max), @intime datetime, @outtime datetime, @dstatus varchar(10) ) as declare @whours time = @outtime - @intime select @whours //Your insert query here After inserting so you can get total working hours of an employee per day by using below query declare @IntimeInSeconds int SELECT @IntimeInSeconds = SUM( ( DATEPART(hh, whours) * 3600 ) + ( DATEPART(mi, whours) * 60 ) + DATEPART(ss, whours) ) from Temp_EmpTimes group by EmpId,EmpName, CONVERT(VARCHAR(10),InTime,111),CONVERT(VARCHAR(10),OutTime,111) SELECT CONVERT(VARCHAR(10),@IntimeInSeconds/3600) +':' + RIGHT('00'+CONVERT(VARCHAR(2),(@IntimeInSeconds%3600)/60),2) +':' + RIGHT('00'+CONVERT(VARCHAR(2),@IntimeInSeconds%60),2) AS [HH:MM:SS] This is to get Total In time SELECT EmpId,EmpName,max(OutTime) OTime ,MIN(InTime) ITime ,convert(time, max(OutTime)-MIN(InTime)) as Emp_Intime from Temp_EmpTimes group by EmpId,EmpName, CONVERT(VARCHAR(10),InTime,111),CONVERT(VARCHAR(10),OutTime,111) fyi. . . find attachment Hope this helps you Mark as answer if you are satisfied Download source file sravan Klbaiju, if this helps please login to Mark As Answer. \| Alert Moderator

Hi,
Before you insert every row to the table calculate the difference between intime and outtime and insert the value in Whours column. So, you get the Employee working hours for that particular Row (time) .
do this for every row.
Best way to insert values by passing first 5 parameters is by using a storedProcedure
and mentions working hours logic as mention above in my post

create procedure SpDailyWhours

(

@empid int,

@empname  varchar(max),

@intime datetime,

@outtime datetime,

@dstatus varchar(10)

)

as

declare @whours time  = @outtime - @intime

select @whours 

//Your insert query here

After inserting so you can get total working hours of an employee per day by using below query

declare @IntimeInSeconds int

SELECT @IntimeInSeconds = SUM(

             ( DATEPART(hh, whours) * 3600 ) +

             ( DATEPART(mi, whours) * 60 ) +

               DATEPART(ss, whours)

          ) from Temp_EmpTimes 

group by EmpId,EmpName, CONVERT(VARCHAR(10),InTime,111),CONVERT(VARCHAR(10),OutTime,111)



SELECT CONVERT(VARCHAR(10),@IntimeInSeconds/3600)  

    +':' 

    + RIGHT('00'+CONVERT(VARCHAR(2),(@IntimeInSeconds%3600)/60),2) 

    +':' 

    + RIGHT('00'+CONVERT(VARCHAR(2),@IntimeInSeconds%60),2) AS [HH:MM:SS]

This is to get Total In time

SELECT EmpId,EmpName,max(OutTime) OTime ,MIN(InTime) ITime ,convert(time, max(OutTime)-MIN(InTime)) as Emp_Intime from Temp_EmpTimes 

group by EmpId,EmpName, CONVERT(VARCHAR(10),InTime,111),CONVERT(VARCHAR(10),OutTime,111)

0	Hi, Use case Statement to achieve your goal. If time is less than the input time then return one value otherthan return some other. EX: select case when intime >8:35 and intime < 11:00 then 'L' when intime > 11:00 then 'halfday' from tablename Klbaiju, if this helps please login to Mark As Answer. \| Alert Moderator
