AND and OR expression in Doctrine ODM

Question

I need to transform a SQL request into a DQL request :

SELECT * FROM object WHERE stardate >= GETDATE() AND enddate <= GETDATE() OR stardate >= GETDATE() AND enddate IS NULL

I tried with :

$now = new \DateTime();
$qb = $this->createQueryBuilder()
    ->field('startDate')->lte($now)
    ->field('endDate')->gte($now);

$qb->addOr(
    $qb->expr()
        ->field('startDate')->lte($now)
        ->field('endDate')->exists(false)
);

return $qb->getQuery()->execute();

But It's not correct.

Answer 1

The solution :

$now = new \DateTime('01/01/2018');
$qb = $this->createQueryBuilder();
$qb->addOr(
    $qb->expr()
        ->field('startDate')->lte($now)
        ->field('endDate')->gte($now)
);
$qb->addOr(
    $qb->expr()
        ->field('startDate')->lte($now)
        ->field('endDate')->exists(false)
);

return $qb->getQuery()->execute();
