in reply to retrieving primary key from a DBIx::Class package

You're almost there.

What you need to do is 1. get your ResultSet's data source, i.e. what it gets the actual data from; in DBIC, this is a ResultSource object, and it's what you're describing when you're writing e.g.

package MyApp::Schema::Result::Artist; use base qw/DBIx::Class::Core/; # this ResultSource is going to be based on a table, not a view __PACKAGE__->table('artist'); # the table has these columns __PACKAGE__->add_columns(qw/ artistid name /); # and this is the pkey __PACKAGE__->set_primary_key('artistid');

and then 2. get the pkey info from the ResultSource. So we get:

my $result_source = $schema->resultset('Artist')->result_source; my @list_of_columns_in_pkey = $result_source->primary_columns;

Edit: I just realized, I assumed you were starting from a ResultSet object, but if you already know its name beforehand:

my $result_source = $schema->source('Artist'); my @list_of_columns_in_pkey = $result_source->primary_columns;
