Question

I want to calculate SumofWorkingHours as below which is based in empID. e.g. if EmpID is 1 then it sum the working hours in every Admincode and display sum in all rows where EmpID exist.
Please give suggestion or query regarding this.

LoginName   EmpID      Practice      AdminCode     WorkingHours  SumofWorkingHours
E1          1          Admin         IT            5.24          38.81 
E1          1          Admin         Finance       0.07          38.81 
E1          1          Admin         HR           33.50          38.81

This data is only for testing

Answer 1

Looks like you just want to sum over EmpId, like this:

select EmpId, sum(WorkingHours)
from theTable
group by EmpId

To integrate that into a larger query to specifically return the result set that you show in your question, you could do something like:

select t1.LoginName, t1.EmpID, t1.Practice, 
    t1.AdminCode, t1.WorkingHours, tot.SumofWorkingHours
from theTable t1
inner join (select EmpID, sum(WorkingHours) as SumofWorkingHours
            from theTable
            group by EmpId) tot 
on tot.EmpID = t1.EmpID
