Question

Hi
I have a table with something like this
::: inidicates column seperation
col1 ::: col2 ::: col3 ::: col4
ab,abc,abvfg,fghy ::: x1 ::: y1 ::: z1
ba,mkl,huji,kill ::: x2 ::: y2 ::: z2
I want to get something like this :
col1 ::: col2 ::: col3 ::: col4
ab ::: x1 ::: y1 ::: z1
abc ::: x1 ::: y1 ::: z1
abvfg ::: x1 ::: y1 ::: z1
fghy ::: x1 ::: y1 ::: z1
and so on......
Either a procedure or a single sql statement is fine..
PS: the first column can have any number of words separated with comma (,)
Please advise
Thanks in advance

Answer 1

create table kris (
a varchar2(200),
b varchar2(20),
c varchar2(20),
d varchar2(20));
insert into kris values('ab,abc,abvfg,fghy', 'x1','y1','z1');
insert into kris values('ba,mkl,huji,kill', 'x2','y2','z2');
select substr(','||a||',', instr(','||a||',', ',', 1, rn) +1,
     instr(','||a||',', ',', 1, rn+1) - instr(','||a||',', ',', 1, rn) -1)
     v,b,c,d
from (select length(a) - length(translate(a, '1,', '1')) +1 L,
     a, b, c, d from kris) t, (select rownum rn from cat) c
     where c.rn <= t.L
order by a, rn;
V B C D
ab x1 y1 z1
abc x1 y1 z1
abvfg x1 y1 z1
fghy x1 y1 z1
ba x2 y2 z2
mkl x2 y2 z2
huji x2 y2 z2
kill x2 y2 z2
