Question

当我执行查询时，它看起来像这样：

SELECT p FROM AppBundle\Entity\Shrubs p 

WHERE p.botanicalname LIKE :botanicalname 

AND p.commonname LIKE :commonname 

AND p.borderlinehardy = :x

ORDER BY p.commonname ASC

但我希望x周围有引号。在查询中，我有这样的特定行：

andWhere("p.$key = :x")

但如果我在x周围添加单引号，我会得到＆＃34;无效的参数编号＆＃34;错误。如何在不得到错误的情况下在x周围加上引号？

编辑：我的整个查询如下：

 $shrubs = $query
            ->where($query->expr()->like('p.botanicalname', ':botanicalname'))
            ->setParameter('botanicalname', '%' . $botanicalname . '%')
            ->andwhere($query->expr()->like('p.commonname', ':commonname'))
            ->setParameter('commonname', '%' . $commonname . '%')
            ->orderBy('p.commonname', 'ASC');

        $checkfor = array("wetsoil"=>"Tolerates Wet Soil",
            "borderlinehardy"=>"Borderline Hardy",
            "moistsoil"=>"Prefers Moist Soil",
            "peatysoil"=>"Prefers Peaty Soil",
            "welldrainedsoil"=>"Prefers Well-drained Soil",
            "drought"=>"Tolerates Drought",
            "claysoil"=>"Tolerates Clay Soil",
            "sandysoil"=>"Prefers Sandy Soil",
            "loamsoil"=>"Prefers Loam Soil",
            "infertilesoil"=>"Tolerates Infertile Soil",
            "richsoil"=>"Prefers Rich Soil",
            "compactedsoil"=>"Tolerates Compacted Soil",
            "cityconditions"=>"Tolerates City Conditions",
            "pollution"=>"Tolerates Pollution",
            "salt"=>"Tolerates Salt Conditions",
            "windy"=>"Tolerates Windy Conditions",
            "shade"=>"Prefers Shade",
            "partshade"=>"Prefers Part Shade",
            "fullsun"=>"Prefers Full Sun");

        reset($checkfor);

        foreach ($checkfor as $key => $value) {
            if (${$key} == "x") {
                $shrubs = $query->andWhere("p.$key = ':x'")
                    ->setParameter('x', $key)
                    ->getQuery()
                    ->getResult();
            }
        }

为每次通话构建空洞查询

$checkfor = array("wetsoil"=>"Tolerates Wet Soil",
            "borderlinehardy"=>"Borderline Hardy",
            "moistsoil"=>"Prefers Moist Soil",
            "peatysoil"=>"Prefers Peaty Soil",
            "welldrainedsoil"=>"Prefers Well-drained Soil",
            "drought"=>"Tolerates Drought",
            "claysoil"=>"Tolerates Clay Soil",
            "sandysoil"=>"Prefers Sandy Soil",
            "loamsoil"=>"Prefers Loam Soil",

reset($checkfor);


foreach ($checkfor as $key => $value) {
      if (${$key} == "x") {
          //create for each call a full query , 
          //maybe you have not $this, then chnage it, 
          //but get a new instacne
          $query = $this->entityManager->createQueryBuilder();
         //create 
         $shrubs = $query
            ->where($query->expr()->like('p.botanicalname', ':botanicalname'))
