[DDC-1986] findBy hydration with limit and offset with Oracle database (oci8 driver)

Tue, 8 Jan 2013 09:33:00 +0000

I tried to use the findBy method with limit and offset parameters against an Oracle database using oci8 driver.

The query seems to executed successfully but the hydrator fails when hydrating data as there is a DOCTRINE_ROWNUM column appending the "limit" clause.

Here is the exception thrown : "Notice: Undefined index: DOCTRINE_ROWNUM in [...]/vendor/doctrine/orm/lib/Doctrine/ORM/Internal/Hydration/SimpleObjectHydrator.php line 183"

I was thinking about something like this to fix this issue :

add an attribute (platformExtraColumns) to the platform class, storing every column added by methods like doModifyLimitQuery
check in hydrator method hydrateRowData if the column exists among the extra columns attribute of the custom platform
don't use the column if true

Maybe there is a better approach, what are your thoughts?

[DDC-1879] Orphans are neither nulled nor removed when merging a graph of detached entities

Wed, 23 Jan 2013 22:24:05 +0000

When merging a graph of detached entities, the created entitied are created and the updated entities are updated but the non-present entities (which exist in the database but are not in the graph) are neither removed nor have them their association column nullified.

Example :

In my code I have 2 entities : Parent and Child. There is a OneToMany(cascade=

{"all"}

, orphanRemoval=true) relation defined in Parent.

In my database I have a Parent row with an id of 1, which has 3 Children with ids 1,2,3.

When I write the following code, I expect the Parent with id 1 and the Child with id 2 to be updated, a new Child to be created and the Child with id 1 and 3 to be deleted.

$parent = new Parent(); $parent->id = 1  // detached entity
$existing_child = new Child(); $child->id = 2 // detached entity
$new_child = new Child(); // new entity
$dinner->addChild($existing_child);
$dinner->addChild($new_child);

$em->merge($dinner);

$em->flush();

The objects I expect to be created and updated have the correct behaviour but the old children are not touched, they are still present in the database.

[DDC-1803] Paginator usage with a DQL query that is using 2 time the same named binded value failed

Fri, 25 Jan 2013 15:29:52 +0000

I use a dql query where I bind a named parameter 2 time in the same query for different joined fields. The query work but the count query failed saying that there are missing bind variable.

ex:
$qb = $this->getQueryBuilder()
->select('
partial fl.

{id, title, listing_date, abstract}

,
partial fla.

{id},
partial ca.{id}

,
partial ds.

{id}

')
->from('Fo_Listing', 'fl')
->join('fl.listing_properties', 'flp')
->join('flp.property', 'fp')
->leftjoin('fl.listing_assets', 'fla')
->leftjoin('fla.asset', 'ca')
->leftjoin('ca.ds', 'ds')
->where('fp.id = :propertyId')
->setParameter('propertyId', $id)
->andWhere('fl.object_status_id <> :deleted')
->setParameter('deleted', CoRefObjectStatus::DELETE)
->andWhere('fl.publishing_status_id = :published')
->setParameter('published', CoRefPublishingStatus::PUBLISHED)
->andWhere('fp.object_status_id <> :deleted')
->setParameter('deleted', CoRefObjectStatus::DELETE)
->andWhere('fp.publishing_status_id = :published')
->setParameter('published', CoRefPublishingStatus::PUBLISHED)
->add('orderBy', 'fl.listing_date DESC, fl.published_date DESC')
->setMaxResults($onTheMarketLimit);

$onTheMarket = new Paginator($qb, $fetchJoin = true);

To make it work, I've renamed the second usage of the named variable with a 2 at the end. deleted2 and published2.

[DDC-2193] Named native query bug?

Mon, 31 Dec 2012 04:02:50 +0000

@NamedNativeQueries is a useful thing, but I have found some problems during my using.
1、Normal

 /**
 * @NamedNativeQueries({
 *      @NamedNativeQuery(
 *          name            = "fetchMultipleJoinsEntityResults",
 *          resultSetMapping= "mappingMultipleJoinsEntityResults",
 *          query            = "SELECT * FROM test "
 *      )
 * })
 */

2、Error，cannot connect to the server

 /**
 * @NamedNativeQueries({
 *      @NamedNativeQuery(
 *          name            = "fetchMultipleJoinsEntityResults",
 *          resultSetMapping= "mappingMultipleJoinsEntityResults",
 *          query            = "SELECT * 
            FROM test "
 *      )
 * })
 */

3、Cannot use alias.The same problem as the second one.

.......
 query            = "SELECT a as test FROM test "

[DDC-2424] Removing an inherited entity via a delete cascade constraint does not remove the parent row

Mon, 6 May 2013 10:19:39 +0000

For a parent class:

/**
 * @ORM\Entity
 * @ORM\Table(name="Base")
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="discr", type="string")
 * @ORM\DiscriminatorMap({"child1" = "Child1", "child2" = "Child2"})
 */

and simple Child1 & Child2 entities.

With another entity (let's call it ExternalEntity) having a bidirectional OneToOne relation owned by Child1:

class Child1 extends Base
{
  /**
   * @ORM\OneToOne(targetEntity="ExternalEntity", inversedBy="xxx")
   * @ORM\JoinColumn(onDelete="CASCADE", nullable=false)
   */
   private theForeignKey;
}

Enough for the context.
The symptoms:

$em->remove(instanceOfExternalEntity);

removes the ExternalEntity row and the Child1 row. But a dangling row in the Base table is still there for the now inexistent Child1 instance.

Though, a manual delete of either the associated Child1 OR Base row and then the ExternalEntity works.

The problem with the cascading deletion of the parent seems to be only present when deleting through a MYSQL cascading delete from another row which has a foreign key on a child. (Not tested with a foreign key on the parent though)

[DDC-2147] Custom annotation in MappedSuperclass

Tue, 7 May 2013 21:24:53 +0000

When you try use custom annotation in mappedsuperclass like here http://pastebin.com/YMxKvcLk and then i try get metadata for class i get this error
Undefined index: fieldName
ClassMetadataInfo.php function addInheritedFieldMapping
Problem is that custom annotation doesnt have fieldName.
Quick fix is add condition to test if fieldName isset.

[DDC-2449] Amazon Redshift Support

Wed, 15 May 2013 23:09:12 +0000

It would be nice to get doctrine compatible with Amazon Redshift. It uses a Postgres connector but there are some differences. I'm currently facing an issue with the primary id, in Redshift the generation of an id is different from Postgres and so I'm getting errors associated with generating an id.

Here are some references that might be useful:
node-orm faced the same issue and seems like they figured it out: https://github.com/dresende/node-orm2/issues/39

[DDC-2035] XML Mapping : add attribute "length" for tag "id"

Sat, 29 Sep 2012 19:17:03 +0000

XML mapping :

<id name="id" type="string" length="16"/>

Generate SQL :

id varchar(255) not null

It's not possible with XML mapping to have :

 id varchar(16) not null

Because tag "id" doesn't support "length" attribute.
Please add this attribute

[DDC-1630] Get PersistentCollection::getDeleteDiff is empty when collection changes from 1 item to zero items

[DDC-1494] Query results are overwritten by previous query.

Sat, 9 Feb 2013 20:26:53 +0000

I am running a query that JOINs three tables, with a simple WHERE:

$q = $em->createQuery("

SELECT cat, n, c
FROM Project_Model_NoticeCategory cat
JOIN cat.notices n
JOIN n.chapters c
WHERE
c.id = :chapter_id

");

When I do this:

  $q->setParameter('chapter_id', 1);
  $a = $q->getResult();

  $q->setParameter('chapter_id', 2);
  $b = $q->getResult();

$b always has the wrong results. Running the following code:

  $q->setParameter('chapter_id', 1);
  $a = $q->getResult();

  $q->setParameter('chapter_id', 2);
  $b = $q->getResult();
  $z = $q->getArrayResult();

BUG Results: $b != $z (getArrayResult IS CORRECT, it refreshes the results) Note: $a==$b (which is wrong)

Explanation:

There is a chapter table, this has a many-to-many join to notices (these are meta info
about the chapter – a little like tagging a blog post) the notices are grouped into
categories.

Data model:

/**
 * @Entity
 * @Table(name="chapter")
 */
class Project_Model_Chapter
{
    /**
     * @Id @Column(type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;
 
    /** @Column(type="string") */
    private $title;

	/**
	 * @ManyToMany(targetEntity="Project_Model_Notice", mappedBy="chapters")
	 */
	private $notices;
	
	.... /lots of code snipped/ ....
	
}


/**
 * @Entity
 * @Table(name="notice")
 */
class Project_Model_Notice
{
	/**
     * @Id @Column(type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;
 
    /** @Column(type="string") */
    private $title;
	
	/**
	 * @ManyToMany(targetEntity="Project_Model_Chapter", inversedBy="notices")
	 * @JoinTable(name="chapter_notice")
	 */
	private $chapters;
	
	/**
	 * @ManyToOne(targetEntity="Project_Model_NoticeCategory", inversedBy="notices")
	 */
	private $notice_category;
	
	.... /lots of code snipped/ ....
	
}

/**
 * @Entity
 * @Table(name="notice_category")
 */
class Project_Model_NoticeCategory
{
    /**
     * @Id @Column(type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;
	/** @Column(type="string") */
    private $title;
	
	/**
	 * Bidirectional - One-To-Many (INVERSE SIDE)
	 *
	 * @OneToMany(targetEntity="Project_Model_Notice", mappedBy="notice_category", cascade={"persist", "remove"})
	 */
	private $notices;

	.... /lots of code snipped/ ....
	
}

Data fixtures:

$tools = new \Project_Model_NoticeCategory;
$tools->setTitle('Tools');
		
$spanner = new \Project_Model_Notice;
$spanner->setTitle('spanner');
$tools->addNotice($spanner);
		
$drill = new \Project_Model_Notice;
$drill->setTitle('power drill');
$tools->addNotice($drill);
		
$this->em->persist($tools);
$this->em->flush();

$tools = new \Project_Model_NoticeCategory;
$tools->setTitle('Safety');
		
$gloves = new \Project_Model_Notice;
$gloves->setTitle('gloves');
$tools->addNotice($gloves);
		
$goggles = new \Project_Model_Notice;
$goggles->setTitle('goggles');
$tools->addNotice($goggles);
		
$this->em->persist($tools);
$this->em->flush();

$chapter1 = new \Project_Model_Chapter;
$chapter1->setTitle('Chapter 1');
$this->em->persist($chapter1);

$chapter2 = new \Project_Model_Chapter;
$chapter2->setTitle('Chapter 2');
$this->em->persist($chapter2);

$chapter1->addNotice($spanner);
$chapter1->addNotice($gloves);

$chapter2->addNotice($spanner);
$chapter2->addNotice($gloves);
$chapter2->addNotice($drill);
$chapter2->addNotice($goggles);

// now persist and flush everything

Initial investigation:

I think it has something to do with HINT_REFRESH ? Stepping through:

ObjectHydrator->_hydrateRow
ObjectHydrator->_getEntity

when it requests the Project_Model_Category from the unit of work, it
seems that the second query is simply grabbing the cached results from
the first results. This MUST be wrong as the second query uses a
different query (the ID changes) and all the results are wrong.

[DDC-2281] Validation against database-first generated xml requires that the column order within a composite primary key match the order the columns are in in mapping xml

Thu, 9 May 2013 16:30:08 +0000

In using a database-first approach utilizing orm:convert-mapping to generate xml, the validation and schema-tool reports that my composite primary key (ex. Columns A, C, B) be dropped and added in the order in which the mapping appears in the xml (ex. Columns A, B, C).

These columns are not auto-increment and are simply a mixture of int and varchar.
