Getting Doctrine DQL results the SQL way

When performing a DQL query such as:

SELECT u AS user, t AS transaction
FROM Model\User u
JOIN Model\Transaction t WITH t.user = u

You get alternating rows of results, such as:

['user' => Model\User(1)]
['transaction' => Model\Transaction(1)]
['transaction' => Model\Transaction(2)]
['user' => Model\User(2)]
['transaction' => Model\Transaction(3)]
['transaction' => Model\Transaction(4)]
['transaction' => Model\Transaction(5)]

Is it possible to get the result the SQL way, like:

['user' => Model\User(1), 'transaction' => Model\Transaction(1)]
['user' => Model\User(1), 'transaction' => Model\Transaction(2)]
['user' => Model\User(2), 'transaction' => Model\Transaction(3)]
['user' => Model\User(2), 'transaction' => Model\Transaction(4)]
['user' => Model\User(2), 'transaction' => Model\Transaction(5)]

It would be much easier to deal with than alternating objects.

Solution

The way I do it now is:

$query = $em->createQuery('
    SELECT u, t
    FROM Model\User u
    JOIN Model\Transaction t WITH t.user = u
');

$rows = $query->getResult();
$rowCount = count($rows);

$result = [];

for ($i = 0; $i < $rowCount; $i += 2) {
    /** @var Model\User $user */
    $user = $rows[$i];

    /** @var Model\Transaction $transaction */
    $transaction = $rows[$i + 1];

    $result[] = new UserTransactionDTO($user, $transaction);
}

return $result;

Which is clean enough.

Note that this example is a bad one, as you could only return Transactions and get the User from there; but I regularly encounter use cases where a single object does not hold all the information.
