recursive

I'm doing some data migration from a horribly designed database to a less horribly designed database. There is a many to many relationship that has a primary key in one table that corresponds to a comma separated list in another.

FK_ID | data
-------------
1,2   | foo
3     | bar
1,3,2 | blarg

Is there a way to output the FK_ID field with each comma separated element as a single line in the result set?

result set
FK_ID | data
-------------
1     | foo
2     | foo
3     | bar
1     | blarg
2     | blarg
3     | blarg

I'm thinking this would require some sort of recursive query which I don't think mysql has.

Thanks in advance.
