Hydrating with enumType as array gives *string* instead of Enum (DQL with join)

[mzk]

Bug Report

When I have a query:

return $this->entityManager->createQuery('SELECT o.orderStatus FROM Entity\Order o')
            ->getResult(AbstractQuery::HYDRATE_ARRAY);

Then $result[0]['orderStatus'] is instance of BackendEnum OrderStatus.

But when I have a query:

return $this->entityManager->createQuery('SELECT o FROM Entity\Order o')
            ->getResult(AbstractQuery::HYDRATE_ARRAY);

Then $result[0]['orderStatus'] is simple string.

Our Order entity field:

    #[Column(type: Types::STRING, nullable: false, enumType: OrderStatus::class, options: ['charset' => 'utf8', 'collation' => 'utf8_unicode_ci'])]
    private OrderStatus $orderStatus;

Q	A
BC Break	no
Version	2.13.1

Summary

It should be the same result for both cases.

Current behavior

SELECT o retuns string, SELECT o.orderStatus returns the BackendEnum

How to reproduce

Use entity as described and fetch from query builder as an array.

Expected behavior

SELECT o returns an array that contains BackendEnum.

I generally try to avoid Array Hydration, but I agree that this should work nonetheless. If you use standard object hydration (default) is there any issue?

[mzk]

The default object hydration works fine.

The biggest issue I see here is the same reasoning I wrote in #9622:

Migrating from enums used as custom types to this native form is impossible as it behaves differently
