Question

I have a values table:

+------------+---------+
| name       | value   |
+------------+---------+
| parameter1 | 53.8462 |
| parameter2 | 7.6923  |
| parameter3 | 23.0769 |
| parameter4 | 15.3846 |
+------------+---------+

What is the query for sum values of the three last parameters (parameter 2, parameter 3, parameter 4) without the first parameter (parameter1)?

Answer 1

This may be a bit simplistic, but can’t you do this:

select sum(value) from table where name != 'parameter2'

If what you are really after is the sum past n-th value, you could do this (in SQL Server):

WITH OrderedRows AS
(
    SELECT name, value,
    ROW_NUMBER() OVER (ORDER BY name) AS 'RowNumber'
    FROM table 
) 
SELECT sum(value) 
FROM OrderedRows 
WHERE RowNumber > 1;
