Question

I have three tables in my database.

First table is Employee:

Second table is EmployeeTimeIn : (HoursConsumed have time in seconds!)

Third table is EmployeeTimeOut:

I wrote the following SQL query which lists all the employees grouped by their IDs and working time of each time in session:

select 
    v.EID, e.EmployeeName, v.Time_In, v.Time_Out,
    convert(varchar(5), SUM(v.HoursConsumed) / 3600)  + ':' + 
    convert(varchar(5), SUM(v.HoursConsumed) % 3600 / 60) + ':' + 
    convert(varchar(5), (SUM(v.HoursConsumed) % 60)) as workingtime,
    v.Date_Ref
from
    (select 
         e1.EID, e1.Time_In, e2.Time_Out, e1.HoursConsumed,    
         CONVERT(VARCHAR(10), e1.Date_Ref, 111) as Date_Ref
     from EmployeeTimeIn as e1, EmployeeTimeOut as e2
     where e1.Refid = e2.Refid) as v, Employee as e
     where v.EID = e.EmployeeID
     group by 
          v.EID, e.EmployeeName, v.Time_In, v.Time_Out, v.HoursConsumed, v.Date_Ref;

It produces the following output:

I need to modify this query so that for each employee it shows the grand total working time in workingtime column. In this scenario It will display workingtime of 0:41:53 for EID 4 and 0:0:39 for EID 200.

Please advise.

(NOTE: final output should have three rows for this example data because i need to show Time In and Time Out fields in final table too!)

I assume that you always can convert WorkingTimeInSeconds to hours:

;WITH Totals(WorkingTimeInSeconds, EmployeeId, EmployeeName, DateRef) AS
(
   SELECT 
      e.EmployeeId,
      e.EmployeeName,
      eti.Date_Refб
      SUM(HoursConsumed) WorkingTimeInSeconds,
    FROM Employee e
    JOIN EmployeeTimeIn eti
      ON e.EmployeeId = eti.EId
    GROUP BY 
      e.EmployeeId,
      e.EmployeeName,
      eti.Date_Ref
)

SELECT
  Totals.EmployeeId,
  Totals.EmployeeName,
  eti.Time_In,
  eto.Time_Out,
  eti.Ref_Date,
  eti.WorkingTimeInSeconds
FROM Totals
JOIN EmployeeTimeIn eti
  ON Totals.DateRef = eti.Date_Ref AND eti.EID=Totals.EmployeeId
JOIN EmployeeTimeOut eto
  ON Totals.DateRef = eto.Date_Ref AND eto.EID=Totals.EmployeeId AND eti.RefId = eto.RefId
