Oracle 11 SQL：1行をx行に分割し、新しい列を挿入します

unpivot句を使用できます。このコードはあなたに役立つと思います：

select a,b,c,'Name for ' || name_code || ' : '|| name_code as value  from 
(select 'A' a ,'B' b ,'C' c ,'D' d,'E' e,'F' f,'G' g,'H' h,'I' i from dual) 
unpivot include nulls 
(
name_for for name_code in (d as 'D', e as 'E' ,f as 'F',g as 'G',h  as 'H',i as 'I') 
);

質問の更新後。答えは次のように変更されます：

select A,B,C,'Name for ' || name_for  as value, name_code  from 
(select 1 A,2 B,3 C,'Lennon' D,'Paul McCartney' E, 'Ringo Starr' F, 
              null G, 'Pete Best'H, 'Tommy Moore'  I from dual )
unpivot include nulls 
(
name_for for name_code in (d,e,f,g,h,i) 
)
