Php 学说解释

我在问一个关于查询结果的问题。当我使用MySql和Doctrine时，我没有相同的结果。。。我有一个字段，它在执行时会更改（包->id）

我在Mysql中的查询：

"SELECT * 
FROM packages_dates_prices 
INNER JOIN packages 
ON packages_dates_prices.id = packages.id 
AND packages_dates_prices.package ='.$id.'"

我在存储库和DQL中的查询：

"SELECT a
FROM BackBundle:PackagesDatesPrices a
INNER JOIN BackBundle:Packages b
WHERE a.id = b.id
AND a.package = :id
"

调试工具栏中的查询：

SELECT 
  e0_.id AS id0, 
  e0_.date_start AS date_start1, 
  e0_.date_end AS date_end2, 
  e0_.price AS price3, 
  e0_.id AS id4 
FROM 
  packages_dates_prices e0_ 
  INNER JOIN packages e1_ ON (
    e0_.id = e1_.id 
    AND e0_.id = ?
  )
Parameters: [1] 

实体包：

我在包裹id（字段名称为id）和包裹\日期\价格（字段名称为包裹）之间有一个关系

我还没有发现错误。 我试了很长时间，但我并不真正熟悉教义

感谢您阅读并帮助我。

您可以在Symfony2文档部分中阅读相关内容

您期望的结果可以在不编写任何SQL语句的情况下获得

$package = $this->getDoctrine()->getRepository("BackBundle:Packages")->find($id);
$datesPrices = $package->getDatesPrices();

---

$datesPrices将包含通过OneToMany关系连接的所有行

为了更快地获得更好的帮助，您应该添加一些示例数据（数据库中的2-3条记录）、查询的当前输出和预期输出。您可以使用来设置基本测试用例。因此，如果您确实有

@OneToMany

为什么不充分利用它呢？还有，你能给我们看看你的实体吗？@JovanPerovic:我完成了我的提问。谢谢。@vincent您的帖子中缺少了一些内容，因为dql中的

where

子句在调试查询中不存在？另外，dql

a.package=b.id

中的第一个条件没有任何意义，因为这个

a.package=b.id

谓词已经在

内部连接BackBundle:Packages b

部分进行了计算，它也将在sql中的连接部分中产生相同的条件，dql应该生成类似于您在问题中发布的sql的sql
