Tim, can you elaborate a little? I've tried to find the referenced
documentation but can't. I don't quite understand how a CHAR datatype
can cause this problem.
Thanks.

[Don't call finish at the end of fetch loops. See the docs.]

I'd guess the "type" column is a CHAR field.
Try:
use DBD::Oracle qw(:ora_types);
...
$dbh->{ora_ph_type} = ORA_CHAR
before the prepare(). See
http://search.cpan.org/~timb/DBD-Oracle-1.16/Oracle.pm#Database_Handle_Attributes
See also the String Comparison section in the Datatypes chapter of the
Oracle OCI manual for more details.
Tim.
