+Doctrine ORM is an object-relational mapper for PHP 8.1+ that provides transparent persistence
 for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features

 # Doctrine ORM Documentation
 
+The documentation is written in [ReStructured Text](https://docutils.sourceforge.io/rst.html).
+
 ## How to Generate:
-Using Ubuntu 14.04 LTS:
 
-1. Run ./bin/install-dependencies.sh
-2. Run ./bin/generate-docs.sh
+In the project root, run
 
-It will generate the documentation into the build directory of the checkout.
+    composer docs
 
+This will generate the documentation into the `docs/output` subdirectory.
 
-## Theme issues
+To browse the documentation, you need to run a webserver:
 
-If you get a "Theme error", check if the `en/_theme` subdirectory is empty,
-in which case you will need to run:
+    cd docs/output
+    php -S localhost:8000
 
-1. git submodule init
-2. git submodule update
+Now the documentation is available at [http://localhost:8000](http://localhost:8000).

+Modifying the Output Walker to get the raw SQL with interpolated parameters
+---------------------------------------------------------------------------
+
+Sometimes we may want to log or trace the raw SQL being generated from its DQL
+for profiling slow queries afterwards or audit queries that changed many rows
+``$query->getSQL()`` will give us the prepared statement being passed to database
+with all values of SQL parameters being replaced by positional ``?`` or named ``:name``
+as parameters are interpolated into prepared statements by the database while executing the SQL.
+``$query->getParameters()`` will give us details about SQL parameters that we've provided.
+So we can create an output walker to interpolate all SQL parameters that will be
+passed into prepared statement in PHP before database handle them internally:
+
+.. literalinclude:: dql-custom-walkers/InterpolateParametersSQLOutputWalker.php
+   :language: php
+
+Then you may get the raw SQL with this output walker:
+
+.. code-block:: php
+
+    <?php
+    $query
+        ->where('t.int IN (:ints)')->setParameter(':ints', [1, 2])
+        ->orWhere('t.string IN (?0)')->setParameter(0, ['3', '4'])

+        ->getSQL();
+
+The where clause of the returned SQL should be like:
+
+.. code-block:: sql
+
+    WHERE t0_.int IN (1, 2)
+       OR t0_.string IN ('3', '4')

+Generated Columns
+=================
+
+Generated columns, sometimes also called virtual columns, are populated by
+the database engine itself. They are a tool for performance optimization, to
+avoid calculating a value on each query.
+
+You can define generated columns on entities and have Doctrine map the values
+to your entity.
+
+Declaring a generated column
+----------------------------
+
+There is no explicit mapping instruction for generated columns. Instead, you
+specify that the column should not be written to, and define a custom column
+definition.
+
+.. literalinclude:: generated-columns/Person.php
+   :language: php
+
+* ``insertable``, ``updatable``: Setting these to false tells Doctrine to never
+  write this column - writing to a generated column would result in an error
+  from the database.
+* ``columnDefinition``: We specify the full DDL to create the column. To allow
+  to use database specific features, this attribute does not use Doctrine Query
+  Language but native SQL. Note that you need to reference columns by their
+  database name (either explicitly set in the mapping or per the current
+  :doc:`naming strategy <../reference/namingstrategy>`).
+  Be aware that specifying a column definition makes the ``SchemaTool``
+  completely ignore all other configuration for this column. See also
+  :ref:`#[Column] <attrref_column>`
+* ``generated``: Specifying that this column is always generated tells Doctrine
+  to update the field on the entity with the value from the database after
+  every write operation.
+
+Advanced example: Extracting a value from a JSON structure
+----------------------------------------------------------
+
+Lets assume we have an entity that stores a blogpost as structured JSON.
+To avoid extracting all titles on the fly when listing the posts, we create a
+generated column with the field.

-Implementing the Notify ChangeTracking Policy
-=============================================
-
-.. sectionauthor:: Roman Borschel <roman@code-factory.org>
-
-The NOTIFY change-tracking policy is the most effective
-change-tracking policy provided by Doctrine but it requires some
-boilerplate code. This recipe will show you how this boilerplate
-code should look like. We will implement it on a
-`Layer Supertype <https://martinfowler.com/eaaCatalog/layerSupertype.html>`_
-for all our domain objects.
-
-.. note::
-
-    The notify change tracking policy is deprecated and will be removed in ORM 3.0.
-    (\ `Details <https://github.com/doctrine/orm/issues/8383>`_)
-
-Implementing NotifyPropertyChanged
-----------------------------------
-
-The NOTIFY policy is based on the assumption that the entities
-notify interested listeners of changes to their properties. For
-that purpose, a class that wants to use this policy needs to
-implement the ``NotifyPropertyChanged`` interface from the
-``Doctrine\Common`` namespace.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Persistence\NotifyPropertyChanged;
-    use Doctrine\Persistence\PropertyChangedListener;
-
-    abstract class DomainObject implements NotifyPropertyChanged
-    {
-        private $listeners = array();
-
-        public function addPropertyChangedListener(PropertyChangedListener $listener) {
-            $this->listeners[] = $listener;
-        }
-
-        /** Notifies listeners of a change. */
-        protected function onPropertyChanged($propName, $oldValue, $newValue) {
-            if ($this->listeners) {
-                foreach ($this->listeners as $listener) {
-                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
-                }
-            }
-        }
-    }
-
-Then, in each property setter of concrete, derived domain classes,
-you need to invoke onPropertyChanged as follows to notify
-listeners:
-
-.. code-block:: php
-
-    <?php
-    // Mapping not shown, either in attributes, annotations, xml or yaml as usual
-    class MyEntity extends DomainObject
-    {
-        private $data;
-        // ... other fields as usual
-
-        public function setData($data) {
-            if ($data != $this->data) { // check: is it actually modified?
-                $this->onPropertyChanged('data', $this->data, $data);
-                $this->data = $data;
-            }
-        }
-    }
-
-The check whether the new value is different from the old one is
-not mandatory but recommended. That way you can avoid unnecessary
-updates and also have full control over when you consider a
-property changed.

-
-.. note::
-
-    The notify change tracking policy is deprecated and will be removed in ORM 3.0.
-    (\ `Details <https://github.com/doctrine/orm/issues/8383>`_)
-
-This policy is based on the assumption that the entities notify
-interested listeners of changes to their properties. For that
-purpose, a class that wants to use this policy needs to implement
-the ``NotifyPropertyChanged`` interface from the Doctrine
-namespace. As a guideline, such an implementation can look as
-follows:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Persistence\NotifyPropertyChanged,
-        Doctrine\Persistence\PropertyChangedListener;
-
-    #[Entity]
-    #[ChangeTrackingPolicy('NOTIFY')]
-    class MyEntity implements NotifyPropertyChanged
-    {
-        // ...
-
-        private array $_listeners = array();
-
-        public function addPropertyChangedListener(PropertyChangedListener $listener): void
-        {
-            $this->_listeners[] = $listener;
-        }
-    }
-
-Then, in each property setter of this class or derived classes, you
-need to notify all the ``PropertyChangedListener`` instances. As an
-example we add a convenience method on ``MyEntity`` that shows this
-behaviour:
-
-.. code-block:: php
-
-    <?php
-    // ...
-
-    class MyEntity implements NotifyPropertyChanged
-    {
-        // ...
-
-        protected function _onPropertyChanged($propName, $oldValue, $newValue): void
-        {
-            if ($this->_listeners) {
-                foreach ($this->_listeners as $listener) {
-                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
-                }
-            }
-        }
-
-        public function setData($data): void
-        {
-            if ($data != $this->data) {
-                $this->_onPropertyChanged('data', $this->data, $data);
-                $this->data = $data;
-            }
-        }
-    }
-
-You have to invoke ``_onPropertyChanged`` inside every method that
-changes the persistent state of ``MyEntity``.
-
-The check whether the new value is different from the old one is
-not mandatory but recommended. That way you also have full control
-over when you consider a property changed.
-
-If your entity contains an embeddable, you will need to notify
-separately for each property in the embeddable when it changes

-
-.. code-block:: php
-
-    <?php
-    // ...
-
-    class MyEntity implements NotifyPropertyChanged

-        {
-            if (!$embeddable->equals($this->embeddable)) {
-                // notice the entityField.embeddableField notation for referencing the property
-                $this->_onPropertyChanged('embeddable.prop1', $this->embeddable->getProp1(), $embeddable->getProp1());
-                $this->_onPropertyChanged('embeddable.prop2', $this->embeddable->getProp2(), $embeddable->getProp2());
-                $this->embeddable = $embeddable;
-            }
-        }
-    }
-
-This would update all the fields of the embeddable, you may wish to
-implement a diff method on your embedded object which returns only
-the changed fields.
-
-The negative point of this policy is obvious: You need implement an
-interface and write some plumbing code. But also note that we tried
-hard to keep this notification functionality abstract. Strictly
-speaking, it has nothing to do with the persistence layer and the
-Doctrine ORM or DBAL. You may find that property notification
-events come in handy in many other scenarios as well. As mentioned
-earlier, the ``Doctrine\Common`` namespace is not that evil and
-consists solely of very small classes and interfaces that have
-almost no external dependencies (none to the DBAL and none to the
-ORM) and that you can easily take with you should you want to swap
-out the persistence layer. This change tracking policy does not
-introduce a dependency on the Doctrine DBAL/ORM or the persistence
-layer.
-
-The positive point and main advantage of this policy is its
-effectiveness. It has the best performance characteristics of the 3
-policies with larger units of work and a flush() operation is very
-cheap when nothing has changed.

+    $users = $query->getResult(); // array of CustomerDTO
+
+Note that you can only pass scalar expressions or other Data Transfer Objects to the constructor.
+
+If you use your data transfer objects for multiple queries, and you would rather not have to
+specify arguments that precede the ones you are really interested in, you can use named arguments.
+
+Consider the following DTO, which uses optional arguments:
+
+.. code-block:: php
+
+    <?php
+
+    class CustomerDTO
+    {
+        public function __construct(
+            public string|null $name = null,
+            public string|null $email = null,
+            public string|null $city = null,
+            public mixed|null $value = null,
+            public AddressDTO|null $address = null,
+        ) {
+        }
+    }
+
+You can specify arbitrary arguments in an arbitrary order by using the named argument syntax, and the ORM will try to match argument names with the selected column names.
+The syntax relies on the NAMED keyword, like so:
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(a.city, c.name) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'SMITH', email: null, city: 'London', value: null}
+
+ORM will also give precedence to column aliases over column names :
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(c.name, CONCAT(a.city, ' ' , a.zip) AS value) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'DOE', email: null, city: null, value: 'New York 10011'}
+
+To define a custom name for a DTO constructor argument, you can either alias the column with the ``AS`` keyword.
+
+The ``NAMED`` keyword must precede all DTO you want to instantiate :
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(c.name, NEW NAMED AddressDTO(a.street, a.city, a.zip) AS address) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'DOE', email: null, city: null, value: 'New York 10011'}
+
+If two arguments have the same name, a ``DuplicateFieldException`` is thrown.
+If a field cannot be matched with a property name, a ``NoMatchingPropertyException`` is thrown. This typically happens when using functions without aliasing them.
+
+You can hydrate an entity nested in a DTO :
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW CustomerDTO(c.name, a AS address) FROM Customer c JOIN c.address a');

-Things to note:
-    - The resultset mapping declares the entities retrieved by this native query.
-    - Each field of the entity is bound to a SQL alias (or column name).
-    - All fields of the entity including the ones of subclasses
-      and the foreign key columns of related entities have to be present in the SQL query.
-    - Field definitions are optional provided that they map to the same
-      column name as the one declared on the class property.
-    - ``__CLASS__`` is an alias for the mapped class
-
-
-In the above example,
-the ``fetchJoinedAddress`` named query use the joinMapping result set mapping.
-This mapping returns 2 entities, User and Address, each property is declared and associated to a column name,
-actually the column name retrieved by the query.
-
-Let's now see an implicit declaration of the property / column.

-In this example, we only describe the entity member of the result set mapping.
-The property / column mappings is done using the entity mapping values.
-In this case the model property is bound to the model_txt column.
-If the association to a related entity involve a composite primary key,
-a @FieldResult element should be used for each foreign key column.
-The @FieldResult name is composed of the property name for the relationship,
-followed by a dot ("."), followed by the name or the field or property of the primary key.

+Partial Hydration
+=================

 PHP Mapping
 ===========
 
-Doctrine ORM also allows you to provide the ORM metadata in the form
-of plain PHP code using the ``ClassMetadata`` API. You can write
-the code in PHP files or inside of a static function named
-``loadMetadata($class)`` on the entity class itself.
-
-PHP Files
----------
-
-.. note::
-
-   PHPDriver is deprecated and will be removed in 3.0, use StaticPHPDriver
-   instead.
-
-If you wish to write your mapping information inside PHP files that
-are named after the entity and included to populate the metadata
-for an entity you can do so by using the ``PHPDriver``:
-
-.. code-block:: php
-
-    <?php
-    $driver = new PHPDriver('/path/to/php/mapping/files');
-    $em->getConfiguration()->setMetadataDriverImpl($driver);
-
-Now imagine we had an entity named ``Entities\User`` and we wanted
-to write a mapping file for it using the above configured
-``PHPDriver`` instance:
-
-.. code-block:: php
-
-    <?php
-    namespace Entities;
-
-    class User
-    {
-        private $id;
-        private $username;
-    }
-
-To write the mapping information you just need to create a file
-named ``Entities.User.php`` inside of the
-``/path/to/php/mapping/files`` folder:
-
-.. code-block:: php
-
-    <?php
-    // /path/to/php/mapping/files/Entities.User.php
-
-    $metadata->mapField(array(
-       'id' => true,
-       'fieldName' => 'id',
-       'type' => 'integer'
-    ));
-
-    $metadata->mapField(array(
-       'fieldName' => 'username',
-       'type' => 'string',
-       'options' => array(
-           'fixed' => true,
-           'comment' => "User's login name"
-       )
-    ));
-
-    $metadata->mapField(array(
-       'fieldName' => 'login_count',
-       'type' => 'integer',
-       'nullable' => false,
-       'options' => array(
-           'unsigned' => true,
-           'default' => 0
-       )
-    ));
-
-Now we can easily retrieve the populated ``ClassMetadata`` instance
-where the ``PHPDriver`` includes the file and the
-``ClassMetadataFactory`` caches it for later retrieval:
-
-.. code-block:: php
-
-    <?php
-    $class = $em->getClassMetadata('Entities\User');
-    // or
-    $class = $em->getMetadataFactory()->getMetadataFor('Entities\User');
+Doctrine ORM also allows you to provide the ORM metadata in the form of plain
+PHP code using the ``ClassMetadata`` API. You can write the code in inside of a
+static function named ``loadMetadata($class)`` on the entity class itself.
 
 Static Function
 ---------------
 
-In addition to the PHP files you can also specify your mapping
-information inside of a static function defined on the entity class
-itself. This is useful for cases where you want to keep your entity
-and mapping information together but don't want to use attributes or
-annotations. For this you just need to use the ``StaticPHPDriver``:

-
-It makes sense to generate the entity code if you are using entities as Data

-however putting much more logic on the entities you should refrain from using
-the entity-generator and code your entities manually.

-    code manually for inheritance to work!

-Convert Mapping Information
----------------------------
-
-Convert mapping information between supported formats.
-
-This is an **execute one-time** command. It should not be necessary for
-you to call this method multiple times, especially when using the ``--from-database``
-flag.
-
-Converting an existing database schema into mapping files only solves about 70-80%
-of the necessary mapping information. Additionally the detection from an existing
-database cannot detect inverse associations, inheritance types,
-entities with foreign keys as primary keys and many of the
-semantical operations on associations such as cascade.
-
-.. note::
-
-    There is no need to convert YAML or XML mapping files to annotations
-    every time you make changes. All mapping drivers are first class citizens
-    in Doctrine 2 and can be used as runtime mapping for the ORM. See the
-    docs on XML and YAML Mapping for an example how to register this metadata
-    drivers as primary mapping source.
-
-To convert some mapping information between the various supported
-formats you can use the ``ClassMetadataExporter`` to get exporter
-instances for the different formats:
-
-.. code-block:: php
-
-    <?php
-    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
-
-Once you have a instance you can use it to get an exporter. For
-example, the yml exporter:
-
-.. code-block:: php
-
-    <?php
-    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
-
-Now you can export some ``ClassMetadata`` instances:
-
-.. code-block:: php
-
-    <?php
-    $classes = array(
-      $em->getClassMetadata('Entities\User'),
-      $em->getClassMetadata('Entities\Profile')
-    );
-    $exporter->setMetadata($classes);
-    $exporter->export();
-
-This functionality is also available from the command line to
-convert your loaded mapping information to another format. The
-``orm:convert-mapping`` command accepts two arguments, the type to
-convert to and the path to generate it:
-
-.. code-block:: php
-
-    $ php bin/doctrine orm:convert-mapping xml /path/to/mapping-path-converted-to-xml
-
-Reverse Engineering
--------------------
-
-You can use the ``DatabaseDriver`` to reverse engineer a database to an
-array of ``ClassMetadata`` instances and generate YAML, XML, etc. from
-them.
-
-.. note::
-
-    Reverse Engineering is a **one-time** process that can get you started with a project.
-    Converting an existing database schema into mapping files only detects about 70-80%
-    of the necessary mapping information. Additionally the detection from an existing
-    database cannot detect inverse associations, inheritance types,
-    entities with foreign keys as primary keys and many of the
-    semantical operations on associations such as cascade.
-
-First you need to retrieve the metadata instances with the
-``DatabaseDriver``:
-
-.. code-block:: php
-
-    <?php
-    $em->getConfiguration()->setMetadataDriverImpl(
-        new \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
-            $em->getConnection()->getSchemaManager()
-        )
-    );
-
-    $cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory();
-    $cmf->setEntityManager($em);
-    $metadata = $cmf->getAllMetadata();
-
-Now you can get an exporter instance and export the loaded metadata
-to yml:
-
-.. code-block:: php
-
-    <?php
-    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
-    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
-    $exporter->setMetadata($metadata);
-    $exporter->export();
-
-You can also reverse engineer a database using the
-``orm:convert-mapping`` command:
-
-.. code-block:: php
-
-    $ php bin/doctrine orm:convert-mapping --from-database yml /path/to/mapping-path-converted-to-yml
-
-.. note::
-
-    Reverse Engineering is not always working perfectly
-    depending on special cases. It will only detect Many-To-One
-    relations (even if they are One-To-One) and will try to create
-    entities from Many-To-Many tables. It also has problems with naming
-    of foreign keys that have multiple column names. Any Reverse
-    Engineered Database-Schema needs considerable manual work to become
-    a useful domain model.

-Merging entities
-----------------
-
-Merging entities refers to the merging of (usually detached)
-entities into the context of an EntityManager so that they become
-managed again. To merge the state of an entity into an
-EntityManager use the ``EntityManager#merge($entity)`` method. The
-state of the passed entity will be merged into a managed copy of
-this entity and this copy will subsequently be returned.
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $detachedEntity = unserialize($serializedEntity); // some detached entity
-    $entity = $em->merge($detachedEntity);
-    // $entity now refers to the fully managed copy returned by the merge operation.
-    // The EntityManager $em now manages the persistence of $entity as usual.
-
-
-The semantics of the merge operation, applied to an entity X, are
-as follows:
-
-
--  If X is a detached entity, the state of X is copied onto a
-   pre-existing managed entity instance X' of the same identity.
--  If X is a new entity instance, a new managed copy X' will be
-   created and the state of X is copied onto this managed instance.
--  If X is a removed entity instance, an InvalidArgumentException
-   will be thrown.
--  If X is a managed entity, it is ignored by the merge operation,
-   however, the merge operation is cascaded to entities referenced by
-   relationships from X if these relationships have been mapped with
-   the cascade element value MERGE or ALL (see ":ref:`transitive-persistence`").
--  For all entities Y referenced by relationships from X having the
-   cascade element value MERGE or ALL, Y is merged recursively as Y'.
-   For all such Y referenced by X, X' is set to reference Y'. (Note
-   that if X is managed then X is the same object as X'.)
--  If X is an entity merged to X', with a reference to another
-   entity Y, where cascade=MERGE or cascade=ALL is not specified, then
-   navigation of the same association from X' yields a reference to a
-   managed object Y' with the same persistent identity as Y.
-
-The ``merge`` operation will throw an ``OptimisticLockException``
-if the entity being merged uses optimistic locking through a
-version field and the versions of the entity being merged and the
-managed copy don't match. This usually means that the entity has
-been modified while being detached.
-
-The ``merge`` operation is usually not as frequently needed and
-used as ``persist`` and ``remove``. The most common scenario for
-the ``merge`` operation is to reattach entities to an EntityManager
-that come from some cache (and are therefore detached) and you want
-to modify and persist such an entity.
-
-.. warning::
-
-    If you need to perform multiple merges of entities that share certain subparts
-    of their object-graphs and cascade merge, then you have to call ``EntityManager#clear()`` between the
-    successive calls to ``EntityManager#merge()``. Otherwise you might end up with
-    multiple copies of the "same" object in the database, however with different ids.
-
-.. note::
-
-    If you load some detached entities from a cache and you do
-    not need to persist or delete them or otherwise make use of them
-    without the need for persistence services there is no need to use

-Unique Constraints
-------------------
-
-It is possible to define unique constraints by the following declaration:
-
-.. code-block:: yaml
-

-      type: entity
-      fields:

-Development of new applications often starts with an existing database schema.
-When the database schema is the starting point for your application, then
-development is said to use the *Database First* approach to Doctrine.
-
-In this workflow you would modify the database schema first and then
-regenerate the PHP code to use with this schema. You need a flexible
-code-generator for this task.

-We spun off a subproject, Doctrine CodeGenerator, that will fill this gap and
