Symfony2 / Doctrine2-获取SQL最小，最大日期值

Question

My problem is when i want to get the max or the min date value between 2013-04-08,2013-04-07 and 2013-04-06, the response is always 2013-04-08 for the min and the max

my script :

$max_date =     $em ->createQuery("SELECT MAX(p.date) FROM TrackingMarqueBundle:PointdeventeOperateursSaisie p")
                        ->getSingleScalarResult();
    $min_date =     $em ->createQuery("SELECT MIN(p.date) FROM TrackingMarqueBundle:PointdeventeOperateursSaisie p")
                        ->getSingleScalarResult();

Any help please?

Answer 1

Maybe

$em ->createQuery("SELECT MAX(p.date) max_date,MIN(p.date) min_date FROM TrackingMarqueBundle:PointdeventeOperateursSaisie p")->getArrayResult();

I have this code works correctly
