Hibernate-style `#[Formula]` computed fields for Doctrine ORM 3 entities.

Adds support for read-only, SQL-computed entity properties populated via subqueries, aggregations and joins — without N+1 queries.

```
#[ORM\Entity]
class Customer
{
    #[Formula('(SELECT COUNT(*) FROM orders o WHERE o.customer_id = {this}.id)')]
    public int $orderCount = 0;
}
```

Requirements
------------

[](#requirements)

- **PHP >= 8.2.0** but the latest stable version of PHP is recommended

Install
-------

[](#install)

### Symfony

[](#symfony)

If you are using Symfony, install the bundle instead — it wires everything automatically via Symfony DI:

```
composer require cryonighter/formula-doctrine-bundle
```

See [cryonighter/formula-doctrine-bundle](https://github.com/cryonighter/formula-doctrine-bundle)for installation and configuration instructions.

### Standalone

[](#standalone)

If you use another framework or write in bare PHP:

```
composer require cryonighter/formula-doctrine
```

Bootstrap the stack manually when creating your `EntityManager`:

```
