I thought that WITH could be used only for SELECT statements.
Oh wait, you want to use the WITH statement as a

If it's OK to use the sqlite3 cmd line shell then try this:
-- create test input table X
create table X (what text);
insert into X values ('abc,def');
-- write X to a file
.output mydata.csv
select * from X;
.output stdout
-- read it back in to parse it
create table Y (a text, b text);
.mode

You will thank yourself by using a scripting language such Ruby, php, or
python.
Is there a reg ex library for sqlite that could be employed?

It probably can be done with just SQLite's built-in text functions such as
instr and substr,
although with 20 to 30 items it may get a bit messy and complex.

What do you mean by "parse" ? Just to separate a string into
I have a table of roughly 500k records with a number of fields
containing delimited text that needs to be parsed and written to
separate tables as a master lists. In order to do this I need to
parse the field contents, however, I don't see any functions within
SQLite to enable that. The number
Might be doable with a recursive CTE
