问题 is it possible to make : $q->createQuery('q') ->whereIn('q.id', $q2) Where $q2 is an other Doctrine_Query object. Because my subquery is complex and I don't want to write it in SQL... 回答1: Unfortunately, according to the Doctrine API documentation, you can't pass another query object to whereIn() , so you will have to fetch your ID-s beforehand and pass them in an array. Be careful though, because if you pass an empty array, then there will be NO FILTERING for those ID-s. In other words: it

问题 Is it possible to do a RIGHT OUTER JOIN in Doctrine 2 DQL? 回答1: As far as I know, there is still no way to do that in DQL, and the reason might be that it does not make much sense from an ORM perspective, according to one of the lead developers. Nevertheless, the feature request, although very old, is still open; so it might be implemented in the future. 来源： https://stackoverflow.com/questions/7957987/doctrine-dql-right-join

问题 I am having issues implementing a sub-select solution for ORDERING a resulting dataset before the GROUP BY reduces it. Normally, in SQL you would do a sub-select: SELECT * FROM ( SELECT * FROM a_table order by a_table.timestamp desc ) as table_tmp group by userId However, I am having difficulty implementing this in DQL. Can anyone point me in the right direction please? My query is more complex than this and I assume I JOIN other tables through 'table_tmp' and in the outer SELECT. Thanks. 回答1

问题 I'm building an app using Symfony2 framework and using Doctrine ORM. I have a table with airlines for which some IATA codes are missing. I'm outputting a list, ordered by this IATA code, but I'm getting the undesirable result that the records with null IATA codes are sorted at the top. In MySQL this is simple enough to do, with ORDER BY ISNULL(code_iata), code_iata but I'm clueless as to what the equivalent would be for DQL. I tried $er->createQueryBuilder('airline')->orderBy('ISNULL(airline

问题 I am doing a Java project connected to Documentum data storage and I need to create a ACL using DQL . Any idea on how can I do that ?

问题 Ads entity is described by geographic information: Country> Region>County . The Ads entity is only linked with County . Consequently, retrieving Ads by countries will require us joining entities twice. My goal is counting the number of Ads for a given country. For that, I tried this DQL query but without success: public function getMotorsAdsCountByCountry($slug){ $qb = $this->_em->createQueryBuilder() ->select("m.id, COUNT(m.id) AS cnt") ->from("MinnAdsBundle:MotorsAds", "m") ->join("m.county
