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

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
