Question

I have the following table

color       shape         material       value    qt
----------------------------------------------------
green       cylinder      plastic         12       2
white       cube          wood            5        1
green       cylinder      plastic         6        2
white       cube          wood            5        2
green       cylinder      plastic         2        2

I want to have the sum of values that have the same criteria. I want something like the following.

color       shape         material       sum
-----------------------------------------------
green       cylinder      plastic        28
white       cube          wood           15
green       cylinder      plastic        12

I have a lot of colors, shapes and materials so I would like a dynamic query. I don’t know where to start.

EDIT

There is other characteristics that makes every record different

Answer 1

select color, shape, material, sum( value * qt )
from tbl
group by color, shape, material
