Just the data moved; the server running the scripts hasn't changed since the move, aside from me pointing my DBI connections to the new server, literally only updating the "Server=oldserver;" to "Server=newserver". Both of my servers are Windows Server 64 2008.

I don't think there is anything in DBD::ODBC which would cause this and
since you are using the same DBD::ODBC in both cases this would also
indicate this. It is however possible that the second server is
returning a different type for the columns. You could test this by
issuing the query and then examining the TYPE and PRECISION attributes
for each column (see
http://search.cpan.org/~timb/DBI-1.613/DBI.pm#Statement_Handle_Attributes).
