Answer 1

You can write a doctrine extension to do the job:
Xyz\SomeBundle\DoctrineExtension\DayOfWeek.php
class DayOfWeek extends FunctionNode
{
public $date;
/**
* #override
*/
public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker)
{
return "DAYOFWEEK(" . $sqlWalker->walkArithmeticPrimary($this->date) . ")";
}
/**
* #override
*/
public function parse(\Doctrine\ORM\Query\Parser $parser)
{
$parser->match(Lexer::T_IDENTIFIER);
$parser->match(Lexer::T_OPEN_PARENTHESIS);
$this->date = $parser->ArithmeticPrimary();
$parser->match(Lexer::T_CLOSE_PARENTHESIS);
}
}
app/config/config.yml
doctrine:
orm:
auto_generate_proxy_classes: "%kernel.debug%"
entity_managers:
default:
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
dql:

dayofweek: Xyz\SomeBundle\DoctrineExtension\DayOfWeek

It is not possible to use all of the SQL functions with the query builder. Some of them are defined (AVG, SUM, etc), but most aren't (including DAY/WEEK/MONTH).
You can still write native SQL:
// creating doctrines result set mapping obj.
$rsm = new Doctrine\ORM\Query\ResultSetMapping();
// mapping results to the message entity
$rsm->addEntityResult('AppBundle\Entity\Post', 'p');
$rsm->addFieldResult('p', 'id', 'id');
$rsm->addFieldResult('p', 'postDate', 'postDate');
$sql = "SELECT id, postDate
FROM your_table
WHERE YEAR(postDate) = ?
AND [...]";
$query = $this->_em->createNativeQuery($sql, $rsm);
$query->setParameter(1, $your_year_here);
$query->getResult();
