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) =

In Symfony 4 you must install DoctrineExtensions:

composer require beberlei/DoctrineExtensions

And then edit the doctrine config file (config/packages/doctrine.yaml) as follow:

doctrine:
    orm:
        dql:
            string_functions:
                MONTH: DoctrineExtensions\Query\Mysql\Month
                YEAR: DoctrineExtensions\Query\Mysql\Year
