I have a varchar variable with contents like this: '123,12,7654321,9998...'. I work in Oracle 10gR2. How can I achieve the following output format?:
------
123
12
7654321
9998
...
------
Thanks!
Try this
SELECT EXTRACTVALUE(COLUMN_VALUE,'text()') VALS
FROM XMLTABLE('123,12,7654321,9998');
or
SELECT COLUMN_VALUE VALS FROM XMLTABLE('123,12,7654321,9998');
Here is a way using connect
:
with str as (select '123,12,7654321,9998' as val from dual)
select cast(regexp_substr(val,'[^,]+', 1, level) as int)
from str
connect by cast(regexp_substr(val, '[^,]+', 1, level) as int) is not null;
I'll admit that I adapted it from this article . What you are trying to do is commonly put into a function called "split".
Try this :
/* Formatted on 1/30/2013 1:24:07 PM (QP5 v5.227.12220.39724) */
WITH val AS (SELECT '123,12,7654321,9998' txt FROM DUAL)
SELECT REGEXP_SUBSTR (txt,
'[0-9]+|[a-z]+|[A-Z]+',
1,
lvl)
FROM (SELECT txt,
LEVEL lvl
FROM val
CONNECT BY LEVEL <= LENGTH (txt)
- LENGTH (REPLACE (txt,
','))
+ 1)
