# Feature: #27057 - Relations to the same table in Extbase

See [forge#27057](https://forge.typo3.org/issues/27057)

## Description

It is now possible to use a domain model where an object is connected to another object of the same class directly

```php
namespace \Vendor\Extension\Domain\Model;
class A {
	/**
	* @var \Vendor\Extension\Domain\Model\A
	*/
	protected $parent;
```

as well as using a domain model where an object has multiple relations to objects of the same class

```php
namespace \Vendor\Extension\Domain\Model;
class A {
	/**
	* @var \Vendor\Extension\Domain\Model\B
	*/
	protected $x;

	/**
	* @var \Vendor\Extension\Domain\Model\B
	*/
	protected $y;
```

as well as indirectly

```php
namespace \Vendor\Extension\Domain\Model;
class A {
	/**
	* @var \Vendor\Extension\Domain\Model\B
	*/
	protected $b;

	/**
	* @var \Vendor\Extension\Domain\Model\C
	*/
	protected $c;

namespace \Vendor\Extension\Domain\Model;
class B {
	/**
	* @var \Vendor\Extension\Domain\Model\C
	*/
	protected $c;
```

Using this kind of relations before was only possible by overriding the Extbase query builder and doing manual queries because the Extbase query builder created wrong SQL statements. Now Extbase properly supports these cases.

## Impact

Extbase now correctly handles relations to objects of the same class.
