There is another alternative, you can use the underlying relationship between Class::DBI and Ima::DBI. As the docs for Class::DBI say:

For more complex queries you need to fall back on the underlying Ima::DBI query mechanism.

There is an example given of a query, using the MySQL 'LIMIT' function:

       Music::Artist->set_sql(most_cds => qq{
                SELECT artist.id, COUNT(cd.id) AS cds
                  FROM artist, cd
                 WHERE artist.id = cd.artist
                 GROUP BY artist.id
                 ORDER BY cds DESC
                 LIMIT 10
        });

        my @artists = Music::Artist->search_most_cds();
