Hur man gör Pivoting i Oracle 10g

Du kan göra det så här i 10G:

select salesboyname, 
       sum (case when product='P1' then amount end) as p1,
       sum (case when product='P2' then amount end) as p2,
       sum (case when product='P3' then amount end) as p3
from   tblsales
group by salesboyname;

I 11G finns ett PIVOT-nyckelord som liknar SQL Servers.
