-between the supported database systems.
-
-As an example, the Doctrine Mapping Type ``string`` defines the
-mapping from a PHP string to a SQL VARCHAR (or VARCHAR2 etc.
-depending on the RDBMS brand). Here is a quick overview of the
-built-in mapping types:
-
--  ``string``: Type that maps a SQL VARCHAR to a PHP string.
--  ``integer``: Type that maps a SQL INT to a PHP integer.
--  ``smallint``: Type that maps a database SMALLINT to a PHP
-   integer.
--  ``bigint``: Type that maps a database BIGINT to a PHP string.
--  ``boolean``: Type that maps a SQL boolean or equivalent (TINYINT) to a PHP boolean.
--  ``decimal``: Type that maps a SQL DECIMAL to a PHP string.
--  ``date``: Type that maps a SQL DATETIME to a PHP DateTime
-   object.
--  ``time``: Type that maps a SQL TIME to a PHP DateTime object.
--  ``datetime``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object.
--  ``datetimetz``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object with timezone.
--  ``text``: Type that maps a SQL CLOB to a PHP string.
--  ``object``: Type that maps a SQL CLOB to a PHP object using
-   ``serialize()`` and ``unserialize()``
--  ``array``: Type that maps a SQL CLOB to a PHP array using
-   ``serialize()`` and ``unserialize()``
--  ``simple_array``: Type that maps a SQL CLOB to a PHP array using
-   ``implode()`` and ``explode()``, with a comma as delimiter. *IMPORTANT*
-   Only use this type if you are sure that your values cannot contain a ",".
--  ``json_array``: Type that maps a SQL CLOB to a PHP array using
-   ``json_encode()`` and ``json_decode()``
--  ``float``: Type that maps a SQL Float (Double Precision) to a
-   PHP double. *IMPORTANT*: Works only with locale settings that use
-   decimal points as separator.
--  ``guid``: Type that maps a database GUID/UUID to a PHP string. Defaults to
-   varchar but uses a specific type if the platform supports it.
--  ``blob``: Type that maps a SQL BLOB to a PHP resource stream

+Partial Hydration Syntax
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default when you run a DQL query in Doctrine and select only a
+subset of the fields for a given entity, you do not receive objects
+back. Instead, you receive only arrays as a flat rectangular result
+set, similar to how you would if you were just using SQL directly
+and joining some data.
+
+If you want to select partial objects or fields in array hydration you can use the ``partial``
+DQL keyword:
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT partial u.{id, username} FROM CmsUser u');
+    $users = $query->getResult(); // array of partially loaded CmsUser objects
+
+You can use the partial syntax when joining as well:
+
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT partial u.{id, username}, partial a.{id, name} FROM CmsUser u JOIN u.articles a');
+    $usersArray = $query->getArrayResult(); // array of partially loaded CmsUser and CmsArticle fields

     $users = $query->getResult(); // array of CustomerDTO
 
-Note that you can only pass scalar expressions to the constructor.
+You can also nest several DTO :

+    $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.

+Query Result Formats (Hydration Modes)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The format in which the result of a DQL SELECT query is returned

-mode specifies a particular way in which a SQL result set is
-transformed. Each hydration mode has its own dedicated method on

+The way in which the SQL result set of a DQL SELECT query is transformed

+``getResult()``
+^^^^^^^^^^^^^^^
 
--  ``Query#getResult()``: Retrieves a collection of objects. The
-   result is either a plain collection of objects (pure) or an array
-   where the objects are nested in the result rows (mixed).
--  ``Query#getSingleResult()``: Retrieves a single object. If the
-   result contains more than one object, an ``NonUniqueResultException``
-   is thrown. If the result contains no objects, an ``NoResultException``
-   is thrown. The pure/mixed distinction does not apply.
--  ``Query#getOneOrNullResult()``: Retrieve a single object. If the
-   result contains more than one object, a ``NonUniqueResultException``
-   is thrown. If no object is found null will be returned.
--  ``Query#getArrayResult()``: Retrieves an array graph (a nested
-   array) that is largely interchangeable with the object graph
-   generated by ``Query#getResult()`` for read-only purposes.
+Retrieves a collection of objects. The result is either a plain collection of objects (pure) or an array
+where the objects are nested in the result rows (mixed):
 
-    .. note::
+.. code-block:: php
 
-        An array graph can differ from the corresponding object
-        graph in certain scenarios due to the difference of the identity
-        semantics between arrays and objects.
+    <?php
+    use Doctrine\ORM\AbstractQuery;
 
+    $query = $em->createQuery('SELECT u FROM User u');
+    $users = $query->getResult();
+    // same as:
+    $users = $query->getResult(AbstractQuery::HYDRATE_OBJECT);
 
+- Objects fetched in a FROM clause are returned as a Set, that means every
+  object is only ever included in the resulting array once. This is the case
+  even when using JOIN or GROUP BY in ways that return the same row for an
+  object multiple times. If the hydrator sees the same object multiple times,
+  then it makes sure it is only returned once.
 
--  ``Query#getScalarResult()``: Retrieves a flat/rectangular result
-   set of scalar values that can contain duplicate data. The
-   pure/mixed distinction does not apply.
--  ``Query#getSingleScalarResult()``: Retrieves a single scalar
-   value from the result returned by the dbms. If the result contains
-   more than a single scalar value, an exception is thrown. The
-   pure/mixed distinction does not apply.
+- If an object is already in memory from a previous query of any kind, then
+  then the previous object is used, even if the database may contain more
+  recent data. This even happens if the previous object is still an unloaded proxy.
 
-Instead of using these methods, you can alternatively use the
-general-purpose method
-``Query#execute(array $params = [], $hydrationMode = Query::HYDRATE_OBJECT)``.
-Using this method you can directly supply the hydration mode as the
-second parameter via one of the Query constants. In fact, the
-methods mentioned earlier are just convenient shortcuts for the
-execute method. For example, the method ``Query#getResult()``
-internally invokes execute, passing in ``Query::HYDRATE_OBJECT`` as
-the hydration mode.

+    namespace MyProject\Hydrators;
+
+    use Doctrine\ORM\Internal\Hydration\AbstractHydrator;

+        {
+            return $this->_stmt->fetchAllAssociative();
+        }
+    }
+
+Next you just need to add the class to the ORM configuration:
+
+.. code-block:: php
+
+    <?php
+    $em->getConfiguration()->addCustomHydrationMode('CustomHydrator', 'MyProject\Hydrators\CustomHydrator');
+
+Now the hydrator is ready to be used in your queries:

-Object Hydration
-^^^^^^^^^^^^^^^^
-
-Object hydration hydrates the result set into the object graph:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_OBJECT);
-
-Sometimes the behavior in the object hydrator can be confusing, which is
-why we are listing as many of the assumptions here for reference:
-
-- Objects fetched in a FROM clause are returned as a Set, that means every
-  object is only ever included in the resulting array once. This is the case
-  even when using JOIN or GROUP BY in ways that return the same row for an

-  recent data. Data from the database is discarded. This even happens if the
-  previous object is still an unloaded proxy.
-
-This list might be incomplete.
-
-Array Hydration
-^^^^^^^^^^^^^^^
-
-You can run the same query with array hydration and the result set
-is hydrated into an array that represents the object graph:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_ARRAY);

-^^^^^^^^^^^^^^^^
-
-If you want to return a flat rectangular result set instead of an
-object graph you can use scalar hydration:

-
-    <?php
-    $query = $em->createQuery('SELECT u FROM CmsUser u');
-    $users = $query->getResult(Query::HYDRATE_SCALAR);
-    echo $users[0]['u_id'];
-
-The following assumptions are made about selected fields using
-Scalar Hydration:
-
-
-1. Fields from classes are prefixed by the DQL alias in the result.
-   A query of the kind 'SELECT u.name ..' returns a key 'u_name' in
-   the result rows.
-
-Single Scalar Hydration
-^^^^^^^^^^^^^^^^^^^^^^^
-
-If you have a query which returns just a single scalar value you can use
-single scalar hydration:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT COUNT(a.id) FROM CmsUser u LEFT JOIN u.articles a WHERE u.username = ?1 GROUP BY u.id');
-    $query->setParameter(1, 'jwage');
-    $numArticles = $query->getResult(Query::HYDRATE_SINGLE_SCALAR);
-
-You can use the ``getSingleScalarResult()`` shortcut as well:
-
-.. code-block:: php
-
-    <?php
-    $numArticles = $query->getSingleScalarResult();
-
-Scalar Column Hydration
-^^^^^^^^^^^^^^^^^^^^^^^
-
-If you have a query which returns a one-dimensional array of scalar values
-you can use scalar column hydration:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('SELECT a.id FROM CmsUser u');

+Partial Objects
+===============
+
+A partial object is an object whose state is not fully initialized
+after being reconstituted from the database and that is
+disconnected from the rest of its data. The following section will
+describe why partial objects are problematic and what the approach
+of Doctrine to this problem is.
+
+.. note::
+
+    The partial object problem in general does not apply to
+    methods or queries where you do not retrieve the query result as
+    objects. Examples are: ``Query#getArrayResult()``,
+    ``Query#getScalarResult()``, ``Query#getSingleScalarResult()``,
+    etc.
+
+.. warning::
+
+    Use of partial objects is tricky. Fields that are not retrieved
+    from the database will not be updated by the UnitOfWork even if they
+    get changed in your objects. You can only promote a partial object
+    to a fully-loaded object by calling ``EntityManager#refresh()``
+    or a DQL query with the refresh flag.
+
+
+What is the problem?
+--------------------
+
+In short, partial objects are problematic because they are usually
+objects with broken invariants. As such, code that uses these
+partial objects tends to be very fragile and either needs to "know"
+which fields or methods can be safely accessed or add checks around
+every field access or method invocation. The same holds true for
+the internals, i.e. the method implementations, of such objects.
+You usually simply assume the state you need in the method is
+available, after all you properly constructed this object before
+you pushed it into the database, right? These blind assumptions can
+quickly lead to null reference errors when working with such
+partial objects.
+
+It gets worse with the scenario of an optional association (0..1 to
+1). When the associated field is NULL, you don't know whether this
+object does not have an associated object or whether it was simply
+not loaded when the owning object was loaded from the database.
+
+These are reasons why many ORMs do not allow partial objects at all
+and instead you always have to load an object with all its fields
+(associations being proxied). One secure way to allow partial
+objects is if the programming language/platform allows the ORM tool
+to hook deeply into the object and instrument it in such a way that
+individual fields (not only associations) can be loaded lazily on
+first access. This is possible in Java, for example, through
+bytecode instrumentation. In PHP though this is not possible, so
+there is no way to have "secure" partial objects in an ORM with
+transparent persistence.
+
+Doctrine, by default, does not allow partial objects. That means,
+any query that only selects partial object data and wants to
+retrieve the result as objects (i.e. ``Query#getResult()``) will
+raise an exception telling you that partial objects are dangerous.
+If you want to force a query to return you partial objects,
+possibly as a performance tweak, you can use the ``partial``
+keyword as follows:
+
+.. code-block:: php
+
+    <?php
+    $q = $em->createQuery("select partial u.{id,name} from MyApp\Domain\User u");
+
+You can also get a partial reference instead of a proxy reference by
+calling:
+
+.. code-block:: php
+
+    <?php
+    $reference = $em->getPartialReference('MyApp\Domain\User', 1);
+
+Partial references are objects with only the identifiers set as they
+are passed to the second argument of the ``getPartialReference()`` method.
+All other fields are null.
+
+When should I force partial objects?
+------------------------------------
+
+Mainly for optimization purposes, but be careful of premature
+optimization as partial objects lead to potentially more fragile
+code.
