Why not use one of the available object oriented persistence modules available on CPAN. Look at this example from Class::DBI:
package Music::DBI;
use base 'Class::DBI';
Music::DBI->set_db('Main', 'dbi:mysql', 'username', 'password');
package Artist;
use base 'Music::DBI';
Artist->table('artist');
Artist->columns(All => qw/artistid name/);
Artist->has_many('cds', 'CD' => artist);
# ...
my $artist = Artist->retrieve($id);
(This module can actually do a lot more interesting things than that)
A good place to look for more info on object oriented persistence is the POOP comparison website.

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).
