OK, it looks like the ODBC driver libOdbcFb.so needs to be recompiled for a
64-bit architecture.

I've submitted a bug report:

http://tracker.firebirdsql.org/browse/ODBC-76

But in the meantime I'm using DBI::InterBase. However this is returning
dates with a 2-character year rather than CCYY, any ideas why this is? If I
use isql_fb (or even my failed ODBC) it returns dates with a 4-character
year. Can I specify that InterBase should return a 4-char year?

Have a good day.

Regards

Steve.
