>I need to sum a set of fields by an other field in a table and i'd like to know if my idea is good enough.
>(It seemed to be a bit clumsy).
>The table is like this

>A       B 	C
>aa      1	1
>bb      2	
>bb      3	
>bb      4	9
>cc      5	5
>dd      6	
>dd      7	
>dd      8	21

>So I should sum field "B" by field "A" in the filed "C". I would use 2 do while loops, one of them goes through the table and the other one would sum up the filed B if there are more than two identical ones in field "A". Does it seem ok?
