I'm afraid that won't work for 128 bit numbers.

The largest integer currently available in MySQL is 'bigint' (nothing to do with Math::Bigint) which can store 64 bits. PERL's internal integer type is also 64 bit. Until recently that wasn't even 64 bit clean and suffered overflows (thankfully now fixed). That's why I had to resort to Math::Bigint. My previous code combined two SQL bigint columns to produce one PERL Math::Bigint but that's slow both for the DB and PERL.
