Assuming your table is called table1, create 2 views:

SQL

create view table1_extended as (
  select
    trid,
    case when accid = 10 then commision end as Comm_10,
    case when accid = 11 then commision end as Comm_11,
    case when accid = 12 then commision end as Comm_12
  from table1
);

create view table1_extended_pivot as (
  select
    trid,
    sum(Comm_10),
    sum(Comm_11),
    sum(Comm_12)
  from table1_extended
  group by trid
);

Then, call:

select  * from table1_extended_pivot
