Description

I have several entities:
*Client
*Payment
*PaymentDeposit
*PaymentWithdraw

PaymentDeposit and PaymentWithdraw extends from entity Payment

Here is the code 

/**
 * @ORM\Entity
 * @ORM\Table(name="client")
 */
class Client 
{
   /**
     * @var int $id
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @var ArrayCollection
     * @ORM\OneToMany(targetEntity="PaymentDeposit", mappedBy="clientTo")
     */
    private $depositPayments;

    /**
     * @var ArrayCollection
     * @ORM\OneToMany(targetEntity="PaymentWithdraw", mappedBy="clientFrom")
     */
    private $withdrawPayments;

}



/**
 * @ORM\Entity
 * @ORM\Table(name="payment")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="type", type="smallint")
 * @ORM\DiscriminatorMap({
 *                        1 = "PaymentDeposit",
 *                        2 = "PaymentWithdraw"})
 */
class Transaction 
{
    /**
     * @var int $id
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @var float
     * @ORM\Column(name="amount", type="decimal", precision=15, scale=5)
     */
    protected $amount;

    /**
     * @var Client
     * @ORM\ManyToOne(targetEntity="Client", inversedBy="withdrawPayments")
     * @ORM\JoinColumn(name="client_from", referencedColumnName="id", onDelete="cascade")
     */
    protected $clientFrom;

    /**
     * @var Client
     * @ORM\ManyToOne(targetEntity="Client",inversedBy="depositPayments")
     * @ORM\JoinColumn(name="client_to", referencedColumnName="id", onDelete="cascade")
     */
    protected $clientTo;

    /**
     * @var int
     * @ORM\Column(type="smallint")
     */
    protected $status;
}   


/**
 * @ORM\Entity
 * @ORM\Table(name="payment_deposit")
 */
class PaymentDeposit extends Transaction
{
    // Additional info
}

/**
 * @ORM\Entity
 * @ORM\Table(name="payment_deposit")
 */
class PaymentWithdraw extends Transaction
{
    // Additional info
}

When I try to get result with such query I got sql error

$queryBuilder = $this->getEntityManager()->createQueryBuilder();

$queryBuilder->select('c')
            ->from('Client', 'c')
            ->leftJoin('c.depositPayments', 'd')
            ->leftJoin('c.withdrawPayments', 'w')
            ->andWhere($queryBuilder->expr()->eq('d.status', ':status'))
            ->andWhere($queryBuilder->expr()->eq('w.status', ':status'));

sql error:
PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't2_.client_to' in 'on clause' (uncaught exception) at project/vendor/doctrine-dbal/lib/Doctrine/DBAL/Connection.php line 628

native sql query(generated)

SELECT c1_.id,  -- other columns
FROM client c1_ 
LEFT JOIN payment_deposit t2_ ON c1_.id = t2_.client_to 
LEFT JOIN payment t3_ ON t2_.id = t3_.id 
LEFT JOIN payment_withdraw t4_ ON c1_.id = t4_.client_from 
LEFT JOIN payment t5_ ON t4_.id = t5_.id 
WHERE  t3_.transaction_status_id = 1 AND t5_.transaction_status_id = 1

Problem is here 

LEFT JOIN payment_deposit t2_ ON c1_.id = t2_.client_to 
LEFT JOIN payment_withdraw t4_ ON c1_.id = t4_.client_from

extended Entities PaymentDeposit, PaymentWithdraw (tables) doesnt have field clientFrom & clientTo they extend them from entity Payment

P.S. I removed unnecessary fields from Entities to make code example more clearly

The problem is probably "@ORM\OneToMany(targetEntity="PaymentDeposit", mappedBy="clientTo")". You should specify "Transaction" here, since the "clientTo" field is on Transaction, not on PaymentDeposit.

I will look into why this happens and if we can fix this, but judging from the description this could be a tricky issue.

Join in this case wuold have to be

SELECT c1_.id,  -- other columns
FROM client c1_ 
LEFT JOIN payment t3_ ON c1_.id = t3_.id 
LEFT JOIN payment_deposit t2_ ON t3_.id = t2_.client_to 
LEFT JOIN payment t5_ ON c1_.id = t5_.id 
LEFT JOIN payment_withdraw t4_ ON t5_.id = t4_.client_from 
WHERE  t3_.transaction_status_id = 1 AND t5_.transaction_status_id = 1

So Doctrine would need to reorder the joins if TargetEntity#MappedBy is inherited.

This is not supported, you have to use as targetEntity, the class where the mappedBy association is in.
