SQL & PL/SQL

I am designing a stored procedure that has a parameter that is spec'd to come in as a comma delimited string, and I need to be able to loop through each delimited element and pass that element to another procedure.

i.e. -
PROCEDURE delete_link
(
pIn_Items_To_Delete IN VARCHAR2 --This is a parameter that contains a delimited list of items
)

So I need to call another procedure from within this procedure to handle the deletion of each item in the delimited list. I know how to call another procedure, but how can l loop through the items....?

I have read a little about using nested tables, but don't understand the entire concept.

Is there an easy way to do this in PL/SQL?

Let me know if anything above is unclear.

Any help would be appreciated.

Thanks!
