You know, actually I started this script as a extension of DBD::File, the problem is that the SQL supported by SQL::Statement( used by DBD::File) is not as flexible as I'm used to, things like:

SELECT *, 'extra', 'columns' FROM table
or
select * from (select 1)
to name a few, aren't supported,
so I ended up using DBD::SQLite because you can be sure that it at least support the official syntax.
