But for my reporting application (part of a bigger application where CRUD will be more often), I need to run some complicated querries. I did find the "Arbitray SQL" article in DBIx's FAQ, but I don't even know how to get to DBIx, if that's the right way, more specifically, 
> Is it possible to get the database handle and run SQL directly as in DBI? I read that from Schema I can get its storage, which is the db handle. But from a Controller, how do I get the schema object, or the db handle? If the DBIx is the correct way to go (which seems a lengthy way to "just" run a query), do I do $c->model('Some::Model')->resultset....?

If you aren't planning to use DBIx::Class at all, I'd recommend

If you're using DBIx::Class, I'd recommend abstracting the query away behind
a resultset method - something like

sub my_custom_query {
  my ($self, @args) = @_;
  my $code = sub {
    my $dbh = shift;
    <run query here>

If this example isn't sufficient, you should be asking on the dbix-class
list, not here.
