Question

Suppose I have table as below:

Class  Student  Maths  English
------------------------------------
 1      a        50       60
 1      b        -        60
 2      c        70       50
 2      d        40        -

And I need a SQL query to produce this result set:

Score        Maths   English  Total
--------------------------------------
 1             50       120     170
 2             110       50     160
Grand Total    160       170    330

Please help.

Answer 1

Try this:

SELECT 
    ISNULL(Class, 'Grand Total') as Score, 
    sum(Maths) as Maths, 
    sum(English) as English,
    sum(Maths) + sum(English) as Total
FROM 
    table 
GROUP BY 
    ISNULL(Class, 'Grand Total')
WITH ROLLUP

Note that this is T-SQL syntax, it might need a little tweaking for MySql or Oracle.
