You should wriote the code to get the dat in you application and then pass
it to TT.

my @formats = MyDB::Format->retrieve_all();

$data{'formats'} = \@formats;

$tt->process(..., \%data, ...);

--template.tt--
[% FOREACH f in formats %]
  [%# do something with each format %]
[% END %]


OR
If you really have to get the data from within TT you'll probably want to
have a look at Template::Plugin::Class
http://search.cpan.org/dist/Template-Plugin-Class/

[%

   USE format = Class('MyDB::Format');
   formats = format.retrieve_all;
%]

[% WHILE f = formats.next %]
  [%# we're running into a problem here with TT iterators
   vs CDBI iterators... hence the while

   [%# do something with each format %]

[% END %]
