Select only distinct columns

i have table T and want select only distinct columns (without correlation between fields)

F1  F2  F3
 1   A   AA
 1   B   BB
 2   B   CC
 2   C   DD
 2   C   EE
 3   C   EE

desired output

 F1   F2   F3
 1    A    AA
 2    B    BB
 3    C    CC
 null null DD
 null null EE

i try

select T.F1, T1.F2 from
(select distinct F1, row_num() rn from T) T
left join (select distinct F2, row_num() rn from T) T1 on T.rn=T1.rn1
left join etc...

can it be simpler?
