# Class for building SQL UNION statements.
#
# By default ORDER BYs are dropped from the relations as the final sort
# order is not guaranteed any way.
#
# Example usage:
#
# union = Gitlab::SQL::Union.new([user.personal_projects, user.projects])
# sql = union.to_sql
#
# Project.where("id IN (#{sql})")
