Perhaps posting some of your code would help in answering the question. Reading the node How do I post a question effectively? may also be a good investment of time.

Comment on Re: Using BLOB fields with Class::DBI and MySQL
I didn't bother cluttering up the post with code, as I didn't think it was particularly instructive. But here's a sample:
The database setup code:
package MyDatabase::Candidates;
use base 'MyDatabase::DBI';
MyDatabase::Candidates->table('CANDIDATES');
MyDatabase::Candidates->columns(
All => qw/CANDIDATEID CV/);
