来自Doctrine QueryBuilder的DQL不起作用

问题描述

我试图花费几个小时来执行一个简单的DQL，将两个实体连接起来：

$queryBuilder = $this->_em->createqueryBuilder('a');
    
    $queryBuilder = $this->addAssociationCols($queryBuilder);
    $queryBuilder = $this->addDomaineCols($queryBuilder);
// Join entities
$queryBuilder
    ->from(Association::class,'a')
    ->innerJoin(Domaine::class,'d',Join::ON,'d.id = a.domaine_id')
    ->orderBy('a.nom');

但是getQuery（）引发了QueryException：

Fatal error: Uncaught Doctrine\ORM\Query\QueryException: **SELECT a.nom,a.sigle,a.dateCreation,d.domaine FROM IDea\Entities\Association a INNER JOIN IDea\Entities\Domaine d ON d.id = a.domaine_id ORDER BY a.nom ASC** in /var/www/vhosts/location-micro-service.ctb/htdocs/vendor/doctrine/orm/lib/Doctrine/ORM/Query/QueryException.PHP:43 

Stack trace:
