Howto Write normal sentence in SQL












1















I want to write this sentence for DQL :



SELECT id FROM `article` WHERE `created_at` IN (select max(created_at) from article)


I try this one but i have some error :



return $this->createQueryBuilder('p')
->select('p.id')
->where('p.createdAt IN (select max(p.createdAt)from p)')
->getQuery()
->getResult();


Error :



[Semantical Error] line 0, col 88 near 'p)': Error: Class 'p' is not defined.


Thanks a lot,
ibynmax

          You'll also need to write out the subquery in the query builder:



          $subQuery = $this->createQueryBuilder('p')
          ->select('max(p.createdAt)');

          $queryBuilder = $this->createQueryBuilder('p');

          return $queryBuilder
          ->select('p.id')
          ->where($queryBuilder->expr()->in('p.createdAt', $subQuery->getDQL()))
          ->getQuery()
          ->getResult();
