[Bioperl-l] (no subject)

Dear there:
I am the beginner for using Bio::DB::GFF module. So, I have some questions about
that.
I used bp_genbank2gff.pl to convert genbank file to gff file. 
And then I try to load gff file into Database.My script is as follows:

#!/usr/local/bin/perl
use Bio::DB::GFF;
$file="/db/user/external/sying/project_test/NC002489_2.gff";
my $db=Bio::DB::GFF->new(-adaptor=>'dbi::mysqlopt',
                                        -dsn=>'dbi:mysql:ying');
$db->initialize(-erase=>1);
$db->load_gff($file);

Firstly, I create my database: ying. And then try to load gff file into
database. But it doesn't work. So,  I wonder something wrong with my script.
Hope someone can help me.
Thanks a lot!
