预期的学说查询构建器语法错误 =, <, <=, <>, >, >=, !=, got end of string

Question

Having following error:

"[Syntax Error] line 0, col -1: Error: Expected =, <, <=, <>, >, >=, !=, got end of string."

building this query with doctrine querybuiler :

SELECT * 
FROM area 
WHERE ST_Contains(polygon, ST_GeomFromText('POINT(13.405584 52.510621)', 1));

(Sf4 and Doctrine 2.6)

Orm config:

orm:
    dql:
      numeric_functions:
        ST_Contains: CrEOF\Spatial\ORM\Query\AST\Functions\MySql\STContains
        ST_GeomFromText: App\Infrastructure\Persistence\Doctrine\STGeomFromText
        POINT: CrEOF\Spatial\ORM\Query\AST\Functions\MySql\Point

STGeoFromText Class:

use CrEOF\Spatial\ORM\Query\AST\Functions\AbstractSpatialDQLFunction;

class STGeomFromText extends AbstractSpatialDQLFunction
{
    protected $platforms = array('mysql');

    protected $functionName = 'ST_GeomFromText';

    protected $minGeomExpr = 1;

    protected $maxGeomExpr = 2;
}

Construction of the query:

use CrEOF\Spatial\PHP\Types\Geometry\Point;

    $lon = 13.405584;
    $lat = 52.510621;
    $qb = $this->getEntityManager()->createQueryBuilder();
    $qb->select('a.name')
        ->from(Area::class, 'a')
        ->where("ST_Contains(a.polygon, ST_GeomFromText(':point', 1))")
        ->setParameter('point', new Point($lon, $lat), 'point');
    $result = $query->getResult();

same error with:

->where("ST_Contains(a.polygon, ST_GeomFromText(:point, 1))")

notice no presence of symbol ' wrapping the :point parameter.

Answer 1

The error comes from Doctrine/ORM/Query/Parser.php , which tries to parse and validate the query build.

The issue is caused by the parser not "understanding" that ST_Contains returns a boolean value and expects a comparisor operator which could one of the following " =, <, <=, <>, >, >=, != ".

To overcome this, add = true to your condition:

->where("ST_Contains(a.polygon, ST_GeomFromText(:point, 1)) = true")
