Help with output

Question

Hi,
i have two tables
create table mac(ID number, Name varchar2(100))
insert into mac values(1,'Doughnut machine');
insert into mac values(2 , 'Hamburger machine');
insert into mac values(3, 'Ice cream machine');
create table Parts(ID number, Name varchar2(100),fk_mac number)
insert into parts values(1,'Screws',2);
insert into parts values(2, 'Nails', 3);
insert into parts values(3, 'Rivets', 1);
insert into parts values(4, 'Glue', 2);
insert into parts values(5, 'Plates', 2);
insert into parts values(6, 'Panels', 3);
Now i query this table with the following query
select x.id, x.name,y.prt1,y.prt2,y.prt3,y.prt4,y.prt5,y.prt6 from(
select fk_mac,decode(id,1,name,' ')prt1,
decode(id,2,name,' ')prt2,
decode(id,3,name,' ')prt3,
decode(id,4,name,' ')prt4,
decode(id,5,name,' ')prt5,
decode(id,6,name,' ')prt6
from parts)y,mac x
where x.id=y.fk_mac
i get the output as follows
ID NAME     PRT1 PRT2 PRT3 PRT4 PRT5 PRT6
1 Doughnut machine          Rivets               
2 Hamburger machine Screws                         
2 Hamburger machine          Glue          
2 Hamburger machine               Plates     
3 Ice cream machine     Nails                    
3 Ice cream machine                    Panels
I need output as
ID NAME     PRT1 PRT2 PRT3 PRT4 PRT5 PRT6
1 Doughnut machine          Rivets               
2 Hamburger machine Screws          Glue Plates           
3 Ice cream machine     Nails          Panels          
Could someone help me with this...
thanks in advance

Answer 1

i am sorry but the output i am getting with that
subquery is
FK_MAC     PRT1     PRT2     PRT3     PRT4     PRT5     PRT6
1               Rivets               
2                              
3                              
which is not correct i need to get
ID NAME PRT1 PRT2 PRT3 PRT4 PRT5 PRT6
1 Doughnut machine Rivets
2 Hamburger machine Screws Glue Plates
3 Ice cream machine Nails Panels
