I am referring to this stackoverflow answer:
How can I select from list of values in SQL Server
How could something similar be done in O
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.
