try this:
select PA.id,
       PA.pdate,
       PA.ptype,
       count(*),
       sum(PA.amount),
from payment PA
LEFT join computer ba on pa.id=ba.id and ptype = 'computer' 
LEFT join network  ca on pa.id=ca.id and ptype ='network'
LEFT join other da on pa.id=da.id and ptype ='other'
where PA.pdate  BETWEEN TRUNC(sysdate) AND TRUNC(sysdate) + .99999
group by PA.id,PA.pdate,PA.ptype
