PL/SQL - comma separated list within IN CLAUSE

Question

I am having trouble getting a block of pl/sql code to work. In the top of my procedure I get some data from my oracle apex application on what checkboxes are checked. Becaus

Answer 1

Personally, i like this approach:

with t as (select 'a,b,c,d,e' str from dual)
--
select val
from t, xmltable('/root/e/text()'
                 passing xmltype('' || replace(t.str,',','')|| '')
                 columns val varchar2(10) path '/'
                )
