How can I use SQL's YEAR(), MONTH() and DAY() in Doctrine2?

Question

I want to perform a query which would look like this in native SQL:

SELECT
    AVG(t.column) AS average_value
FROM
    table t
WHERE
    YEAR(t.timestamp) =          


        

Answer 1

For Symfony 4:

1. Install: composer require beberlei/doctrineextensions
2. Edit: config\packages\doctrine.yaml

    doctrine:
        orm:
            dql:
                datetime_functions:
                    DAY: DoctrineExtensions\Query\Mysql\Day
                    MONTH: DoctrineExtensions\Query\Mysql\Month
                    YEAR: DoctrineExtensions\Query\Mysql\Year

3. Edit your controller:

    public function somex()
    {
        $em = $this->getDoctrine()->getManager();

        $emConfig = $em->getConfiguration();
        $emConfig->addCustomDatetimeFunction('YEAR', 'DoctrineExtensions\Query\Mysql\Year');
        $emConfig->addCustomDatetimeFunction('MONTH', 'DoctrineExtensions\Query\Mysql\Month');
        $emConfig->addCustomDatetimeFunction('DAY', 'DoctrineExtensions\Query\Mysql\Day');

        $day = '22';
        $month = '4';

        $qb = $em->createQueryBuilder()
            ->select('u')
            ->from('App\Entity\User', 'u')
            ->where('DAY(u.somedate) = :day')
            ->andwhere('MONTH(u.somedate) = :month')
            ->setParameter('month', $day)
            ->setParameter('day', $month)
        ;
        $trab = $qb->getQuery()->getResult();


        return $this->render('intranet/somex.html.twig', [
            'trab' => $trab
        ]);
    }
