You can use the code, but i don't think you can use the sub like that. I think you have to set up a DBI class first, maybe something like this: 
package Foo::DBI;

use base qw(Class::DBI);
use Exception::Database;

Foo::DBI->set_db(
   qw(Main DBI:vendor:database:host user pass),
   {
      RaiseError  => 1,
      PrintError  => 0,
      HandleError => sub {Exception::Database->throw($_[0])},
   },
);

1;

will work for you. I haven't used Exception::Database, however. But i think that will work.

UPDATE:
fixed some code typos from cut-n-paste (must preview more ...)
looks like i was wrong ... but i would create a class anyway ... "when in Rome"
