I've read much wisdom from fellow monks in the past about handling 64 bit numbers in a 32 bit world.

DBI is patently perfect. Math:Bigint is also perfect. But combining the two together isn't doing what I want, but it does do what I expect.

INSTERTing Math:Bigint to MySQL via DBI to a varbinary(16) column (correctly) converts the internal Math:Bigint representation to a binary string.

When SELECTing values back, DBI returns a string.

So when using my favourite fetchall->hashref() I get a string in the hash, and not a Bigint object.

Any way around this? Or is it a one way trip for objects into the DBI API?

What I'd really like is the _inverse_ of parameter binding as exemplified in $sth->bind_param( 3, 123500, { TYPE => SQL_VARCHAR } ); to convert varbinary(16) back into Math::Bigint objects. That would then call the "new" method on Math::Bigint when executing a fetchall->hashref.

Or do you have other wisdom to offer?
