Write “NOT IN” in Doctrine Query Language

Question

I have two tables company(id, ...) and company_has_wtax(company_id, ....). I need to get all companies that are not in company_has_wtax

Answer 1

Try this:

$q2 = $this->createQueryBuilder('c')
    ->select('IDENTITY(c2.company)')
    ->join('RegisterCompanyBundle:CompanyHasMedia', 'c2', 'WITH', 'c2.company = c.id');

$query = $this->createQueryBuilder('c3');
$query->where($query->expr()->notIn('c3.id', $q2->getDQL()));

$companies = $query->getQuery()->getResult();

Please pay attention that we created query from a none related entity by reversedBy/mappedBy
We need to use IDENTIY for the specific field of the related table
