I use the LOB data type for storing/retrieving binary files to/from a table - but apparently the size is very small, i.e. ~2Kb as the file is just a one page Xerox metacode file.

The reason I do this because the physical files are archived in daily basis but we still need to have the file quickly on-the-fly for a period of a month - so having the binary in a database is one option. However I believe storing 120Mb of text into a table is bizarre, if I can't say odd :-)

Btw, here is a snippet of the code:

* On inserting 
   use DBD::Oracle qw(:ora_types);

   __PACKAGE__->data_type(cr_data => DBI::SQL_BINARY);
   __PACKAGE__->data_type(cr_data => { ora_type => ORA_BLOB, 
                                    ora_field => 'column_name' } );

   ....

* On retrieving: 
    # Modify DBH LongReadLen for long binary object...
    my $dbh = __PACKAGE__->db_Main();
    my $current_LongReadLen = $dbh->{LongReadLen};

    # need to dynamically set to the length of your record
    # it's hardcoded to 512Kb for example...
    $dbh->{LongReadLen}     = 512 * 1024; 
    ...

Please refer to the Class::DBI wiki as it has a really good explanation on the subject.

Cheers!
