These days, those varchar strings are actually very likely to be nvarchar
fields (what does MySQL actually say those columns are?) and therefore not
supported by Erlang odbc. Have you tried using ODBC conversion functions to
recast your SQL results, as I suggested?

Unless you're trying to write some kind of DB agnostic
higher-level-do-anything-kind-of-thingamajig (ORM?), and you want to get a
bit of data in and out of the DB, I suggest just casting your values. It's
easier than any other approach.
