Create Doctrine query - mysql

Question

I have a quiz application where played rounds are logged in UserPerformanceEntity. The corresponding MySQL table looks like:
UserPerformance
---------------
id (PK)
user
start_time
end_time
max_level
I want to display some statistics, like 'You performed better than x% of players'. To calculate the percent of players who performed worse than the current I want to execute the following MySQL query:
SELECT COUNT(DISTINCT `user`)
FROM `UserPerformance`
WHERE
(end_time IS NOT NULL
AND end_time NOT LIKE '0000-00-00 00:00:00')
AND `user` != :current_user
AND max_level < :current_level
ORDER BY max_level DESC
But I have no idea how to implement this with doctrine. How should my querybuilder look like?

Answer 1

try this
$query = $this->createQueryBuilder('u');
$query->select('COUNT(DISTINCT u.id) as usercount')
->where('u.end_time IS NOT NULL')
->andWhere('u.end_time NOT LIKE :end_time')
->andWhere('u.id != :current_userid')
->andWhere('u.max_level < :current_level')
->setParameter('end_time', '0000-00-00 00:00:00')
->setParameter('current_userid', $current_userid)
->setParameter('current_level', $current_level)
->setMaxResults(1);
$result = $query->getQuery()->getResult();
return $result[0]['usercount'] ;
The only change is, you need id from current user instead object

Answer 2

Additional information that a user can play many times, so user id is not unique, one user can have many records. This is my solution:
$em = $this->getDoctrine()->getManager();
$qb = $em->createQueryBuilder();
$result = $qb->select('COUNT(DISTINCT p.user) AS usercount')
->from('LoginetFBappVagoBundle:UserPerformanceEntity', 'p')
->where(
$qb->expr()->andX(
$qb->expr()->isNotNull('p.endTime'),
$qb->expr()->neq('p.endTime', ':endTime')))
->andWhere($qb->expr()->neq('p.user', ':userId'))
->andWhere($qb->expr()->lt('p.maxLevel', ':maxLevel'))
->setParameter('endTime', '0000-00-00 00:00:00')
->setParameter('userId', $userid)
->setParameter('maxLevel', $level)
->getQuery()
->getResult();
I started from #Alexander Keil's answer, but I used expressions, and I figured out that there is no need to group the (end_time IS NOT NULL AND end_time NOT LIKE '0000-00-00 00:00:00') part. However if I pass '0000-00-00 00:00:00' in the expression instead setting as a parameter, I get an error. And at last I have to count the distinct users the get the correct result.
