You may not like my wisdom but you get it anyway as you asked for it.

You need to write a stored procedure as your design, storing comma delimited data in a VARCHAR2(2000) is by definition bad. INSERT ALL is a wonderful tool but it can't count an unknown number of commas and substring out what is between them.

If you need someone to write that procedure for you I would suggest a posting in c.d.o.marketplace requesting either a fixed price bid or a per-diem price for the work.

There are many here, including some of my students, who would gladly do your job for you. But I can't think of any willing to do it for free.
