Add a Total of All Columns in a Table using SQL Server 2005/2008

Here's a scenario where you have a table with numeric columns. While displaying all the rows, you also want to display the total of each column at the end. How do you do summarize the data? Use WITH ROLLUP

SAMPLE DATA

DECLARE @Numbers TABLE

(

    ID varchar(10), Marks1 smallint, Marks2 smallint, Marks3 smallint, Marks4 smallint

)

 

INSERT @Numbers

SELECT 'S1', 6, 3, 6, 8 UNION ALL

SELECT 'S2', 4, 8, 1, 9 UNION ALL

SELECT 'S3', 2, 6, 3, 5 UNION ALL

SELECT 'S4', 5, 8, 2, 9 UNION ALL

SELECT 'S5', 5, 5, 3, 5

QUERY

SELECT SUM(Marks1) M1, SUM(Marks2) M2, SUM(Marks3) M3, SUM(Marks4) M4

FROM @Numbers

GROUP BY ID

WITH ROLLUP

RESULT

M1    M2    M3    M4

6    3    6    8

4    8    1    9

2    6    3    5

5    8    2    9

5    5    3    5

22   30   15  36
