Hi,

I have dabbled a bit in the excellent DBIx::Class but currently I am having problems with correlated subqueries..

As I can't really find good documentation, could someone please provide an example for me?

For simplicity I refer to the example-schema in DBIx::Class::Manual::Example (the well-known artists-cds-tracks setting).

To keep it simple, could someone please show me how to do a search on the artist-resultset that has an extra column containing the number of cds belonging to the artist.

I am sure it is easy, but I cannot figure it out (too much beer already?) - sp please enlighten me...

Many thanks!
