# frozen_string_literal: true
# Add support for writing recursive CTEs in ActiveRecord
# Initially from Lorin Thwaits (https://github.com/lorint) as per comment:
# https://github.com/vlado/activerecord-cte/issues/16#issuecomment-1433043310
# Modified from the above code to change the signature to
# `with_recursive(hash)` and extending CTE hash values to also includes arrays
# of values that get turned into UNION ALL expressions.
# This implementation has been merged in Rails: https://github.com/rails/rails/pull/51601
