Order multiple entities by date with query-builder (Symfony) - php

Question

I was wondering if I could possibly order multiple entities by their date of creation with the query builder in Symfony.
This is my query:
public function findContributions(Association $association)
{
return $this->createQueryBuilder('a')
->select('d, ms, m')
->addSelect('greatest(ms.createdAt, d.createdAt) AS date')
->from(Membership::class, 'ms')
->from(Donation::class, 'd')
->leftJoin('ms.member', 'm')
->Where('m.association = a.id')
->andWhere('d.association = a.id')
->orderBy('date', 'DESC')
->getQuery()
->getResult();
}
My results so far :
I would like to order by the column created_at located in both of my entities (membership and donation).
Is there any way I can achieve this?
Thank you !

I think you can use
public function addOrderBy($sort, $order = null); // Default $order = 'ASC'
Doing something like
return $this->createQueryBuilder('a')
->select('d, ms, m')
->addSelect('greatest(ms.createdAt, d.createdAt) AS date')
->from(Membership::class, 'ms')
->from(Donation::class, 'd')
->leftJoin('ms.member', 'm')
->Where('m.association = a.id')
->andWhere('d.association = a.id')
->orderBy('m.date', 'DESC')
->addOrderBy('d.date', 'DESC')
->getQuery()
->getResult();
