Question

I have a question, how can i make a result set making only list of values. For example i have such values : ('1','2','3')
And i want to make a sql that returns such table:

1
2
3

Thanks.

[Edit]

Sorry for wrong question.
Actually list not containing integers, but it contains strings.
I am currently need like (‘aa’,’bb,’cc’).

The best way I’ve found is using XML.

SELECT items.extract('/l/text()').getStringVal() item
FROM TABLE(xmlSequence(
        EXTRACT(XMLType(''||
        REPLACE('aa,bb,cc',',','')||'')
          ,'/all/l'))) items;

Wish I could take credit but alas : http://pbarut.blogspot.com/2006/10/binding-list-variable.html.

Basically what it does is convert the list to an xmldocument then parse it back out.
