Original Pull Request: https://github.com/doctrine/orm/pull/11365

State: closed
Merged: Yes

As discussed in https://github.com/doctrine/orm/issues/8471#issuecomment-2002116608, PARTIAL is re-introduced in 3.2 but only when used with non object hydrators, usefully with array hydration.

This will allow retrieval of partial fields with complex entity dql relationships, example:

    $query = $em->createQuery('SELECT partial u.{id, username}, partial a.{id, name} FROM CmsUser u JOIN u.articles a');
    $users = $query->getArrayResult(); // array of partially loaded CmsUser and CmsArticle fields

Todo:

Test for the partial hydration exception with object hydration mode
Test for UnitOfWork::createEntity with partial keyword usage.
Actual test for array hydrator partial usage
