Php 将原始sql查询与自连接转换为条令queryBuilder查询
您好,我有sql查询:Php 将原始sql查询与自连接转换为条令queryBuilder查询,php,sql,doctrine,symfony4,Php,Sql,Doctrine,Symfony4,您好,我有sql查询: select r.criterion_id, r.logical_state_id, r.created_at from( select acr.criterion_id, max(acr.created_at) as max_date from audit_company_result acr where acr.audit_company_id = 42 group by acr.criterion_id ) as x inner join aud
select r.criterion_id, r.logical_state_id, r.created_at from(
select acr.criterion_id, max(acr.created_at) as max_date from audit_company_result acr
where acr.audit_company_id = 42
group by acr.criterion_id
) as x inner join audit_company_result as r on r.criterion_id = x.criterion_id and r.created_at = x.max_date
$qb = $this->getEntityManager()->getRepository(AuditCompanyResult::class)->createQueryBuilder('acr');
$result = $qb->select('acr')
->addSelect('partial cr.{id}')
->addSelect($qb->expr()->max('acr.createdAt'))
->leftJoin('acr.criterion','cr')
->groupBy('cr.id')
->where('acr.auditCompany=42')
->getQuery()->getArrayResult();
我想翻译成doctrine QueryBuilder表单。我有一个愿望:
审计公司:
class AuditCompany
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="datetime")
*/
private $createdAt;
/**
* @ORM\Column(type="datetime", nullable = true)
*/
private $startedAt;
/**
* @ORM\Column(type="datetime")
*/
private $plannedEnding;
/**
* @ORM\Column(type="datetime", nullable = true)
*/
private $endingAt;
/**
* @ORM\Column(type="boolean")
*/
private $isCertification;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Company", inversedBy="companyAudits")
* @ORM\JoinColumn(nullable=false)
*/
private $company;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Audit", inversedBy="companyAudits")
* @ORM\JoinColumn(nullable=false)
*/
private $audit;
/**
* @ORM\OneToMany(targetEntity="App\Entity\AuditCompanyResult", mappedBy="auditCompany")
*/
private $auditCompanyResults;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Employee")
* @ORM\JoinColumn(nullable=false)
*/
private $responsibleEmployee;
/**
* @ORM\Column(type="datetime", nullable=true)
*/
private $manualStartedAt;
标准:
class Criterion
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="text", nullable=true)
*/
private $info;
/**
* @ORM\Column(type="string", length=255)
*/
private $name;
/**
* @ORM\Column(type="text")
*/
private $algorithmInfo;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $comparableType;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\CategoryCriterion", inversedBy="criteria")
* @ORM\JoinColumn(nullable=false)
*/
private $categoryCriterion;
/**
* @ORM\Column(type="text")
*/
private $logicalMeasureInfo;
/**
* @ORM\OneToMany(targetEntity="App\Entity\CriterionLogicalStateValue", mappedBy="criterion")
*/
private $criterionLogicalStateValues;
/**
* @ORM\Column(type="boolean")
*/
private $isAutomatic;
审计公司结果:
class AuditCompanyResult
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Criterion")
* @ORM\JoinColumn(nullable=false)
*/
private $criterion;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\AuditCompany", inversedBy="auditCompanyResults")
* @ORM\JoinColumn(nullable=false)
*/
private $auditCompany;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $comment;
/**
* @ORM\Column(type="boolean")
*/
private $autoVerified;
/**
* @var datetime $created
*
* @ORM\Column(name="created_at", type="datetime", nullable = false)
*/
private $createdAt;
/**
* @var datetime $updated
*
* @ORM\Column(name="updated_at", type="datetime", nullable = false)
*/
private $updatedAt;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\CriterionLogicalStateValue")
* @ORM\JoinColumn(nullable=false)
*
*/
private $logicalState;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $criterionValue;
/**
* @ORM\Column(type="string", length=255)
*/
private $source;
标准逻辑状态值:
class CriterionLogicalStateValue
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $name;
/**
* @ORM\Column(type="boolean")
*/
private $logicalState;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Criterion", inversedBy="criterionLogicalStateValues")
* @ORM\JoinColumn(nullable=false)
*/
private $criterion;
我只能从上面的sql查询中编写子查询:
select r.criterion_id, r.logical_state_id, r.created_at from(
select acr.criterion_id, max(acr.created_at) as max_date from audit_company_result acr
where acr.audit_company_id = 42
group by acr.criterion_id
) as x inner join audit_company_result as r on r.criterion_id = x.criterion_id and r.created_at = x.max_date
$qb = $this->getEntityManager()->getRepository(AuditCompanyResult::class)->createQueryBuilder('acr');
$result = $qb->select('acr')
->addSelect('partial cr.{id}')
->addSelect($qb->expr()->max('acr.createdAt'))
->leftJoin('acr.criterion','cr')
->groupBy('cr.id')
->where('acr.auditCompany=42')
->getQuery()->getArrayResult();
我不知道如何在QueryBuilder中编写整个查询。有自我连接。与第条完全相同:
但如何将原始sql查询转换为QueryBuilder呢?我将非常感谢你的帮助。
最好的问候懒惰的回答:创建一个存储函数而不读取它的全部内容,如果它只是一个自联接,那么假设您有
$entity\parent
,其中\parent
属性是$entity
的一个实例,您只需执行->联接('entity.parent',p')
。这将告诉ORM在别名“p”下加入“parent”属性的实体。更多信息。(只要确保你的关系不是无限循环)好的,它可以工作。但问题是我什么时候要添加新结果。在保存新结果时,是否有任何方法可以设置与新记录相同的父\u id-like id?
