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
