maybe something like:
select player_number,player_name,cum_score, suma,sumc,sumt,
coalesce(suma,0)+coalesce(sumc,0)+coalesce(sumt,0) as sumtotal
from ( select
player_number,player_name,cum_score,sum(a) as a,sum(c) as c,sum(t) as t from ( select
player_number, player_name, cum_score, (select player_points where
aspect='A') as A ,(select player_points where aspect='C') as C, (select
player_points where aspect='T') as T from (select
* from player as a,teamshare as b where a.player_number=b.player) as c)
as B group by player_number, player_name, cum_score) as foo);
