Repo.get_by(Fisherman, name: "Lew")

account = Repo.one(from a in Account, order_by: [desc: a.id], limit: 1)

  from p in query, where: p.published == true
end

def sorted(query) do
  from p in query, order_by: [desc: p.published_at]
end

Ecto.Adapters.SQL.query(Repo, "SELECT count(1) FROM users", [])
