body: <p>I have this query</p>
  <pre><code>select delivery_first_week_repo.type, delivery_first_week_repo.from_sale, delivery_week_repo.from_sale
  from delivery_first_week_repo
  LEFT JOIN  delivery_week_repo on delivery_first_week_repo.type = delivery_week_repo.type
  where delivery_first_week_repo.week_day = 'Tuesday'
  and delivery_week_repo.week_day = 'Tuesday'
