# Calculate Subtotal of Employee's Hours and add Subtotal to each row

Greetings,
First time on the Forum. Here is my problem.

I have two SQL tables joined as shown below. For each employee, I return the hours worked for each day. My goal is to calculate the subtotal for the week and add the subtotal as a column (Total) for each row. See my example below. I am not sure how to write the SQL script.

Thank you.

Select a.EmpID, b.Day, b.Hrs from Employee a

Inner Join EmployeeHours b on
a.EmpID = b.EmpID

EmpID Day Hrs

12345 Mon 10.0
12345 Tue 0.0
12345 Wed 9.0
12345 Thur 8.0
12345 Fri 11.0

22222 Mon 10.5
22222 Tue 9.5
22222 Wed 9.0
22222 Thur 8.0
22222 Fri 11.0

12345 Thur 8.0 38.0
12345 Fri 11.0 38.0

22222 Mon 10.5 48.0
22222 Tue 9.5 48.0

22222 Fri 11.0 48.0

Try a CTE to sum on EmpID

``````WITH cte AS (
SELECT EmpID, SUM(Hrs) AS THrs
FROM EmployeeHours
GROUP BY EmpID
)
SELECT A.EmpID, A.Day, A.Hrs, cte.THrs
FROM EmployeeHours A
INNER JOIN cte ON A.EmpID = cte.EmpID;``````
``````Select eh.EmpID, eh.Day, eh.Hrs, SUM(eh.Hrs) OVER(PARTITION BY eh.EmpID) AS Total
from EmployeeHours as eh
order by EmpID``````

Scott, this works nicely. Thanks.
