How to ORDER BY CASE in Doctrine2 (Symfony2)

Question

I want to run this query by using Doctrine in Symfony 2.3. But it seems like Doctrine does not understand CASE statement. Can anyone help? Thank you in advance!

Answer 1

I had similar issue, where i had to put a few number prefix'es on the top of result. So I resolved like this:

    $qb = $this->createQueryBuilder('numberPrefix');
    $qb
        ->select('country.code','numberPrefix.prefix')
        ->addSelect('
            (CASE WHEN country.code = :firstCountryCode THEN 1
            WHEN country.code = :secondCountryCode THEN 2
            WHEN country.code = :thirdCountryCode THEN 3
            WHEN country.code = :fourthCountryCode THEN 4
            ELSE 5 END) AS HIDDEN ORD')
        ->innerJoin('numberPrefix.country','country')
        ->orderBy('ORD, country.id')
        ->setParameters(
            [
                'firstCountryCode' => $firstCountryCode,
                'secondCountryCode' => $secondCountryCode,
                'thirdCountryCode' => $thirdCountryCode,
                'fourthCountryCode' => $fourthCountryCode,
            ]
        );
