Project table contains salesman names and percents as shown
below. Single comment column contains  1-2 salesman names and commissions.
How select normalized data from this table ?
 
Andrus.
 
CREATE TABLE project (
id char(10) primary key,
comment char(254)
);
 
insert into test values ('2010-12', 'Aavo 19%, Peedu 15%');
insert into test values ('2010-22', 'Lauri-21%,Peedu 15%');
insert into test values ('2011-33', 'Taavi 21%');
 
How to create select statement in Postgresql 8.1.23 which
selects this data as normalized table like
 
CREATE TABLE commission (
projectid char(10),
salesman  char(5),
commission n(2) )
 
result using data above should be
 
 
'2010-12', 'Aavo', 19
'2010-12', 'Peedu', 15
'2010-22', 'Lauri', 21
'2010-22', 'Peedu', 15
'2011-33', 'Taavi', 21
