Doctrine 2 join on PK in JSONb field - doctrine

Question

In our system we have table to track events. This table named Event have a JSONb column source to hold references to entities in other tables:
| uuid | name | source |
+--------------------------------------+-------------------------------------------+----------------------------------------------------------+
| 7916c5c9-3af2-41ce-81e4-776847029b08 | App\LoginRequest\LoginRequestExpiredEvent | {"loginRequest": "4dda7873-534d-4c0c-853b-65b4b1056dae"} |
Simplified login_request table looks like this:
| uuid | expireAt |
+--------------------------------------+---------------------+
| 4dda7873-534d-4c0c-853b-65b4b1056dae | 2019-02-14 08:00:00 |
| 13c85e8c-e2dc-4b3f-aaf5-25920e2c4d04 | 2019-02-14 22:00:00 |
I would like to SELECT all LoginRequest entities that are referenced in Event table. Please remember that both table doesn't have any foreing-key relation! LoginRequest is referenced only via JSONb field. RAW SQL works like expected:
SELECT *
FROM login_request AS lr
JOIN event AS ev ON ev.source->>'loginRequest' = text(lr.uuid)
returning resultset like:
| lr.uuid | lr.expireAt | ev.uuid | ev.name | ev.source |
+--------------------------------------+---------------------+--------------------------------------+-------------------------------------------+----------------------------------------------------------+
| 4dda7873-534d-4c0c-853b-65b4b1056dae | 2019-02-14 08:00:00 | 7916c5c9-3af2-41ce-81e4-776847029b08 | App\LoginRequest\LoginRequestExpiredEvent | {"loginRequest": "4dda7873-534d-4c0c-853b-65b4b1056dae"} |
I have troubles to get the same functionality as RAW SQL in Doctrine's DQL:
<?php
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Common\Persistence\ManagerRegistry;
use Doctrine\ORM\Query\Expr\Join;
class LoginRequestRepository extends ServiceEntityRepository
{
public function __construct(ManagerRegistry $registry)
{
parent::__construct($registry, LoginRequestEntity::class);
}
public function findExpiredWithEvent()
{
$qb = $this->createQueryBuilder('lr');
$qb
->select('lr')
->join(
EventEntity::class,
'ev',
Join::ON,
"ev.source->>'loginRequest' = text(lr.uuid)"
);
return $qb->getQuery()->getResult();
}
}
I cannot make JOIN on JSONb field prop work. For example above query-builder invocation returns exception:
In QueryException.php line 54:
[Syntax Error] line 0, col 104: Error: Expected end of string, got 'ON'
In QueryException.php line 43:
SELECT lr FROM App\LoginRequest\LoginRequestEntity lr
INNER JOIN App\Event\EventEntity ev
ON ev.source->>'loginRequest' = text(lr.uuid)
Is there posibility to do a JOIN on JSONb column property from other table in Doctrine's query-builder?

Answer 1

I have a similar sql :
select distinct lru.id, lru.* from tstdf_lru as lru inner join tsrec_failure as failure on failure.lru_id = lru.id inner join wrks_event as event on failure.failure_group_id = (event.data->>'failureGroupId')::BIGINT
Maybe that can help you.
