Re: Problem with table joins with Class::DBI

[Roy Johnson]

According to perldoc Class::DBI:

Of course, any query can be added via set_sql, including joins. So, to add a query that returns the 10 Artists with the most CDs, you could write (with MySQL):

        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();

HTH.
