Symfony2 Doctrine query - datetime addition - php

Question

I currently am facing a little problem : I have a table of events, and would like to get which events are upcoming or ongoing.
So for instance we are on a Monday at 12:00, we have 3 events planned for today :
Event A starting at 10:00 and lasting 1h
Event B starting at 11:00 and lasting 2h
Event C starting at 13:00 and lasting 2h
In the end I would like to get Event B (ongoing) and Event C (upcoming).
I tried doing this (didn't work) :
public function findAllPast(\Datetime $datetime)
{
$query = $this->createQueryBuilder('event')
->where('event.startTime + event.duration >= :time')
->setParameter('time', $datetime)
->getQuery();
return $query->getResult();
}
Searching around, I came onto the SQL ADDTIME() function. I'd pretty much like to do a where('ADDTIME(event.startTime, event.duration) >= :time'), but this isn't recognized by Doctrine.
Is there any proper way of doing this without brutal native SQL ?

Answer 1

You could use Doctrine's DATE_ADD() function :
public function findAllPast(\Datetime $datetime)
{
$query = $this->createQueryBuilder('event')
->where('DATE_ADD(event.startTime, event.duration, "days") >= :time')
->setParameter('time', $datetime)
->getQuery();
return $query->getResult();
}
This supposes that event.duration is in days, of course.
EDIT : Alternative in PHP working with DateTime objects
If $duration is in seconds, you can simply :
$datetime->sub(new DateInterval('PT' . $durationInSeconds . 'S')); // or ->add(), depending on what you wnat
and then just use :
public function findAllPast(\Datetime $datetime)
{
$datetime->sub(new DateInterval('PT' . $durationInSeconds . 'S'));
$query = $this->createQueryBuilder('event')
->where('event.startTime >= :time')
->setParameter('time', $datetime)
->getQuery();
return $query->getResult();
}

Alright, here's a working solution with $duration as a time field (much simpler for the form part of the problem) : a custom query
$entityManager = $this->getEntityManager();
$rsm = new ResultSetMappingBuilder($entityManager);
$rsm->addRootEntityFromClassMetadata('Ormindo\EventBundle\Entity\Event', 'event');
$sql = "
SELECT *
FROM events
WHERE ADDTIME(startTime, duration) > '" . $datetime->format("Y-m-d H:i:s") ."'"
;
$query = $entityManager->createNativeQuery($sql, $rsm);
return $query->getResult();
don't forget to use
use Doctrine\ORM\Query\ResultSetMappingBuilder;
Thank you tchap for your time and quick replies :)
