How can I select from list of values in Oracle

If you are seeking to convert a comma delimited list of values:

select column_value 
from table(sys.dbms_debug_vc2coll('One', 'Two', 'Three', 'Four'));

-- Or

select column_value 
from table(sys.dbms_debug_vc2coll(1,2,3,4));

If you wish to convert a string of comma delimited values then I would recommend Justin Cave's regular expression SQL solution.

You don't need to create any stored types, you can evaluate Oracle's built-in collection types.

select distinct column_value from table(sys.odcinumberlist(1,1,2,3,3,4,4,5))
