Question

我有四个表，EdiTransaction，EdiTransactionDetail，EdiDocType和Edi997Details，其中EdiTransaction表与EdiDocType和EdiTransactionDetail有关系，但Edi997Details只与EdiTransaction有关系，其他人没有（请点击请参阅下面的图片）我正在制作一个页面，其中所有的EdiTransaction都带有相应的DocType 856/810，带有PO编号的EdiTransactionDetail和它的Edi997Details。现在我非常坚持如何使用EdiTransaction表检索/加入Edi997Details，因为Edi997Details与EdiDocType和EdiTransactionDetails没有关系。我能够检索除Edi997Details之外的所有内容。

以下是在EdiTransactionRepository中检索EdiTransaction的代码：

public function getAsnDetails ($poNumber,$fileName, $page = 1 , $limit = 15) {

                $em = $this->getEntityManager();
                $query = $em->createQuery(

                        'SELECT partial a.{ediTransactionDetailId, poNumber},
                        partial b.{ediTransactionId, senderId, receiverId, gsNumber, isaNumber, fileName, transactionDate},
                        partial c.{ediDocTypeId, docType}
                        FROM MatrixEdiBundle:EdiTransactionDetail a
                        JOIN a.ediTransaction b
                        JOIN b.ediDocType c
                        WHERE b.fileName LIKE :fileName
                        AND a.poNumber LIKE :poNumber
                        AND c.docType = :doc_type
                        AND a.flag = 1 AND b.flag = 1 
                        ORDER BY b.transactionDate desc')

                ->setParameter('poNumber', "%$poNumber%")
                ->setParameter('fileName', "%$fileName%")
                ->setParameter('doc_type', 856)
                ->setFirstResult(($page - 1) * $limit)
                ->setMaxResults($limit);

                $paginator = new Paginator ($query , $fetchJoinCollection = false );
                $paginator->setUseOutputWalkers(false);
                return $paginator;

        }

这是针对Edi997详细信息：

public function getAsnStatus(){

         $em = $this->getEntityManager();
         $query = $em->createQuery(
                 'SELECT  partial a.{id, ak301, ak401},
                 partial b.{errorCode, condition},
                 partial c.{edi997DetailId, errorCodeId, noOfTrans, acceptedTrans},
                 partial d.{ediTransactionId, senderId, receiverId, gsNumber, isaNumber, fileName}
                 FROM MatrixEdiBundle:Edi997SegmentInError a
                 JOIN a.ediAk403ErrorCodes b
                 JOIN a.edi997Details c
                 JOIN c.ediTransaction d
                 WHERE c.errorCodeId != 0
                 AND d.flag = 1');

                 return $query->getResult();


        }

有没有办法加入Edi997Details和EdiTransaction表，DocType和EdiTransactionDetail不会受到影响？我需要一些关于如何解决这个问题的帮助和想法。我是初学者，也是我第一次访问这个网站。

Answer 1

试试这个：

 table1 -> table2,table3
 table3 -> table1,table2
 table4 -> table2

select a.column,b.column,c.column,d from table1 a join table2 b join  
table3 join table4 d on d.column=b.column where...

Answer 2

这个命名对我没有意义，无论如何我会尝试让你感到困惑的关系：

Edi997＆lt; - ediTransaction - ＆gt; ediDocType

由于学说是面向对象的，你可以做Edi997 - ＆gt; GetEdiTransactions吗？它在查询中是相同的

$qb = $em->createQueryBuilder("Edi997"); //or other entity, it is for test purpose
$qb
  // [...]
  ->innerJoin("Edi997.ediTransactions","ediTransaction")
  ->innerJoin("ediTransaction.ediDocType","ediDocType")
 // [...]
 ->andWhere("ediDocType.attribute = :aParameter")
;

如何将这些表一起加入
