Write a Doctrine2 query to join two spatial tables - symfony

Question

I am using Symfony with Doctrine2 on a Postgre database with PostGIS enabled. I have two tables - property and neighborhood with the following structures:
class Property {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string")
*/
protected $address;
/**
* #var Point $geom
* #ORM\Column(type="Point", nullable=true)
*/
protected $geom;
}
class Neighborhood {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $gid;
/**
* #ORM\Column(type="string")
*/
protected $name;
/**
* #ORM\Column(type="string")
*/
protected $description;
/**
* #var Polygon $geom
*
* #ORM\Column(type="Polygon", nullable=true)
*/
protected $geom;
}
In pgAdminIII, I can write the following query which works fine:
SELECT address, neighborhood.name
FROM property
JOIN neighborhood
ON ST_Contains(neighborhood.geom, property.geom)
How can I write this in DQL? I understand the basics of joins and adding the annotations for the Doctrine2 mapping, but I am not sure how to do the join since the two fields are not equal. I need to use the ST_Contains function to create the join.
I am using the djlambert / doctrine2-spatial bundle for the spatial data types and mapping. I am able to query each table individually and have created maps on each, but am not sure how to select all of the properties in a given neighborhood.

Answer 1

I figured this out and want to post in case someone else has a similar question. I needed to make the ST_Contains part of a condition and not just the function alone.
using the createQueryBuilder, here is the syntax:
$qb = $this->createQueryBuilder('n')
->select("p.address as address, n.ntaname, ST_AsText(p.geom) as function")
->join('Bundle\Entity\Property', 'p', 'WITH', 'ST_Contains(n.geom4326,p.geom)=true');
return $qb->getQuery()
->getResult();

Answer 2

This is not a real answer but just a comment on #George's code.
For me, using creof/doctrine2-spatial:0.0.1 and symfony/symfony:2.3.*, the annotation needed to be lower case for the schema to validate with php app/console doctrine:schema:validate, like this :
/**
* #var Point $geom
* #ORM\Column(type="point", nullable=true)
*/
protected $geom;
With a capital case, I kept getting this error message :
[Doctrine\DBALDBALException]
Unknown column type "Point" requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType(). [...]
