我正在使用Symfony2和Doctrine 2,我正在为Symfony 2的Pagerfanta Bundle创建一个查询。
查询如下:
$qb = $this->createQueryBuilder('t')
->select()
->join('t.pois', 'p');
$qb->groupBy('t.id');
$qb->addOrderBy('count(case when p.image = 1 then 1 else null end)', 'DESC');
将提供以下查询:
SELECT t FROM Bundle\Entity\Turn t INNER JOIN t.pois p GROUP BY t.id ORDER BY count(case when p.image = 1 then 1 else null end) DESC
我首先创建了一个MySQL查询,所以我可以在Doctrine 2中重建它,如下所示:
SELECT *
FROM `turn`
LEFT JOIN (
poi
) ON ( turn.id = poi.turn_id )
GROUP BY turn.id
ORDER BY count( case when poi.image = 1 then 1 else null end) DESC;
这个原生查询工作得很好,在phpmyadmin中测试。
但是,Doctrine 2 Query提出了这个例子:
Twig_Error_Runtime: An exception has been thrown during the rendering of a template ("[Syntax Error] line 0, col 115: Error: Expected end of string, got '('") in Bundle:Admin:showTurnsFiltered.html.twig at line 64.
QueryException: [Syntax Error] line 0, col 115: Error: Expected end of string, got '('
我做错了什么?或者Pagerfanta软件包无法使用此查询?
答案 0 :(得分:0)
我通过向turn
实体(count_poi
)添加一列并通过本机SQL填充它来修复此问题。
之后,查询如下:
SELECT *
FROM `turn`
ORDER BY t.count_poi DESC;
但这只是一种解决方法,我对它不满意,但现在可以使用
