SQL Query to get the Sum of all column values in the last row of a resultset along with row sum (group by)

Question

Can someone please help me to write a query to obtain the TCS and TRS?

ID  Jan Feb Mar TRS
1   4   5   6   15
2   5   5   5   15
3   1   1   1   3
TCS 10  11         


        

Answer 1

This query will do the job

select cast(id as varchar(20)), Jan, Feb, Mar , Jan + Feb + Mar as TRS
from table1

union all

select 'TCS' as id, SUM(Jan) Jan, SUM(Feb) Feb, SUM(Mar) Mar, null as TRS
from table1

The first column will be returned as varchar as this way you have a mix of integers (id) and the text TCS.

Answer 2

You can use GROUP BY and WITH ROLLUP, like this:

SELECT
    id
,   SUM(jan) as jan
,   SUM(feb) as feb
,   SUM(mar) as mar
,   SUM(jan+feb+mar) as TRS
FROM test
GROUP BY id WITH ROLLUP
