Join subquery with doctrine 2 DBAL

Question

I\'m refactoring a Zend Framework 2 application to use doctrine 2.5 DBAL instead of Zend_DB (ZF1). I have the following Zend_Db query:

$subS         


        

Answer 1

Selected answer is over-complicated and the second one is wrong (it won't return anything is the condition is totally fullfilled, meaning if there is no row at all returned by the sub-query).

But yes, you can refactor to use IN:

$qb->leftJoin('user_survey_status_entries', 
              'firstAccess',
              Join::WITH, 
              $qb->expr()->in($qb2->getDQL())
);

In your case, don't forget to move the us.userSurveyID = firstAccess.userSurveyID condition into $qb2.
