I tend to use raw DBI and fetchrow_hashref. Now I have columns by name. That won't be portable across databases (different databases handle capitalization of field names differently)
If you set $dbh->{fetchHashKeyName} = NAME_uc or NAME_lc at the top of your scripts, then the hash fetches will be portable across databases since they'll all be in either uc or lc.
