初始
columnA columnB
abe 10
cd 20
f 3
......
要的结果是这样的
columnA columnB
a 10
b 10
c 20
d 20
e 10
f 3
.......
将columnA的字符串一个一个分割出来
求大神指教
------解决方案--------------------
with
t as (select 'abe' colA,10 colB from dual
union all
select 'cd',20 from dual
union all
select 'f',3 from dual),
t1 as (select level id from dual connect by level<=10)
select substr(t.colA,t1.id,1)colA,t.colB
from t,t1
where t1.id<=length(t.colA)
order by colA;

楼上正解， 那个 10 应该是max(length(columna))
