count of subquery in doctrine - querybuilder












2















I have simple query:



$this->qb->select('l.value')
->addSelect('count(l) AS cnt')
->addSelect('hour(l.time) AS date_hour')
->from(Logs::class, 'l')
->where('l.header = :header')
->groupBy('l.value')
->addGroupBy('date_hour')
->setParameter('header', 'someheader')


This code select 3 columns have one condition and two groupBy.



I want get records count of this query. Of course I dont want to download all records and check size of downloaded data.



Question:
How to rebuild this query and get result from db as singleScalarValue()?

  • This query does not return single scalar result. I have to rebuild it but I dont know how

I think you should use (id column for count) here:



    ->addSelect('count(l) AS cnt')


Something like this, but if you show your Entity i can suggest right solution:



         $this->qb->select('l')
->addSelect('count(l.id) AS cnt')
->addSelect('hour(l.time) AS date_hour')
->from(Logs::class, 'l')
->where('l.header = :header')
->groupBy('l.value')
->addGroupBy('date_hour')
->setParameter('header', 'someheader')

$count = $qb->getQuery()->getSingleScalarResult();

Since GROUP BY + COUNT + getSingleScalarResult does not seem to work together in DQL queries, I guess your best option is to count afterwards



$sub
->select('l.id')
->addSelect('l.value as hidden val')
->addSelect('hour(l.time) AS hidden date_hour')
->from(Logs::class, 'l')
->where('l.header = :header')
->groupBy('val')
->addGroupBy('date_hour')
->setParameter('header', 'someheader')
;

$subIds = array_column($sub->getQuery()->getResult(), 'id');
$count = count($subIds);
