You might want to look at Tie::DBI (by Lincoln Stein) or AnyData (by me). AnyData is a tied-hash interface to DBI (it underlies DBD::AnyData but has a separate user interface). Here's some sample AnyData code:

# create a table
#
$table = adTie( 'CSV','my_db.csv','o',
                 {col_names=>'name,country,sex'}
               );

# insert a row
#
$table->{Sue} = {country=>'de',sex=>'f'};

# delete a single row
#
delete $table->{Tom};

# select a single value
#
$str  = $table->{Sue}->{country};

# loop through table
#
while ( my $row = each %$table ) {
   print $row->{name} if $row->{sex} eq 'f';
}

# select multiple rows
#
$rows = $table->{{age=>'> 25'}}


# update multiple rows
#
$table->{{country=>'Nz'}}={country=>'nz'};

I really recommend that you write to dbi-dev@perl.org to get ideas from Tim and other DBI/DBD authors.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
