I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this (replace tab1 with your table name):
		role, id
from tab1,
	table(select collect(level)
				from dual
			connect by level <= length(role) - length(replace(role, ',')) + 1)
