[DDC-2452] Additional `WITH` condition in joins between JTI roots cause invalid SQL to be produced

Thu, 16 May 2013 16:23:40 +0000

Given a simple Joined Table Inheritance like following:

/**
 * @Entity @Table(name="foo") @InheritanceType("JOINED")
 * @DiscriminatorColumn(name="discr", type="string")
 * @DiscriminatorMap({"foo" = "DDC2452Foo", "bar" = "DDC2452Bar"})
 */
class DDC2452Foo
{
    /** @Id @Column(type="integer") @GeneratedValue */
    public $id;
}

/** @Entity @Table(name="bar") */
class DDC2452Bar extends DDC2452Foo
{
}

Following DQL

SELECT foo1 FROM DDC2452Foo foo1 JOIN DDC2452Foo foo2 WITH 1=1

Will produce broken SQL:

SELECT
    f0_.id AS id0, f0_.discr AS discr1 
FROM 
    foo f0_ 
LEFT JOIN bar b1_ 
    ON f0_.id = b1_.id 
LEFT JOIN foo f2_ 
LEFT JOIN bar b3_ 
    ON f2_.id = b3_.id 
    ON (1 = 1)

(please note the duplicate `ON` in the SQL)

That is caused because of the SQL walker producing the JTI filter with already the `ON` clause in it.

That happens because the JTI join conditions are added in https://github.com/doctrine/doctrine2/blob/2.4.0-BETA2/lib/Doctrine/ORM/Query/SqlWalker.php#L823-L825 (`walkRangeVariableDeclaration`), while the additional defined `WITH` conditions are considered in `walkJoinAssociationDeclaration` later on.

Added a test case and fix at https://github.com/doctrine/doctrine2/pull/668

[DDC-2052] Custom tree walkers are not allowed to add new components to the query

Tue, 14 May 2013 18:18:10 +0000

Custom tree walkers have freedom in modifying the AST but when you try to add a new query component (i.e. new join in walkSelectStatement() ) to the AST then the SqlWalker throws an exception because it does not has the new component in its _queryComponents array. I see two possible ways to resolve this:
1. Modify the Parser class in order to allow tree walkers to modify queryComponents and pass changed queryComponents to the SqlWalker
2. Improve SqlWalker so it can extract and prepare needed information about queryComponent based on AST when it does not have them.

[DDC-2390] Remove Parser and SQLWalker dependency on Query

Thu, 4 Apr 2013 19:35:02 +0000

Query is too powerful to be available in Parser and SQLWalker, because it may lead to accessing data that changes on subsequent runs of a query that is cached.

Idea is to introduce a MetadataBag that contains only the values that are allowed to be accessed.

[DDC-2214] extra single quotation in sql when using EntityRepository::findBy

Mon, 1 Apr 2013 21:50:27 +0000

I'm using symfony 2.1 with mysql.

I have following code:

$related = 
$this->getDoctrine()->getRepository('MyWebBundle:LineRelated')
->findBy(array('line' => $lines), array('count' => 'DESC'), 20);

that generate the sql like this:

SELECT *
FROM line_related t0 
WHERE t0.line_id IN ('6059', 126352, '5677', '6058') 
ORDER BY t0.count DESC 
LIMIT 20

please notice that the sql has extra single quotation around the number 6059,5677 and 6058. which make the sql very slow.

I did a test, when using single quotation,the sql takes 300ms,when using without single quotation,the sql takes 1 ms.

[DDC-1621] Add support for FROM Class1 a1 JOIN Class2 a2 WITH cond queries

Sun, 30 Dec 2012 20:16:47 +0000

Check feasibility of this kind of query different from FROM Class1 a1, Class2 a2 to allow arbitrary joins between classes.

[DDC-2089] Modify OneToMany to allow unidirectional associations without the need of a JoinTable

Sun, 16 Dec 2012 17:42:11 +0000

As I sayd in the title, it would be nice if the ORM layer could permit to map a 1:n association in the db as an unidirectional OneToMany in the classes, without using a JoinTable in the database.
This would permit us to get rid of the unnecessary database JoinTable, which creates disorder and decreases performance for no valuable reason.

Is it possible?

[DDC-1283] Possible issue with PersistentCollection#getDelete/InsertDiff()

Thu, 20 Sep 2012 06:20:49 +0000

Using the following code, when you go from (1, 2) to (1), (2) is deleted as expected. However, if you go from (1, 2) to (2), (1) and (2) are deleted and (2) is then inserted. Is this the desired behaviour? (i.e. 2 extra queries)

$bracket->getTournamentLocations()->takeSnapshot();

$col = $bracket->getTournamentLocations()->unwrap();

$col->clear();

foreach ($form->getValue('tournamentLocations') as $id) {
    $col->add($em->getReference('Tournaments_Model_TournamentLocation', $id));
}

$bracket->getTournamentLocations()->setDirty(true);

[DDC-1599] OnFlush event in transaction

Thu, 20 Sep 2012 06:20:49 +0000

Is there any particular reason why onFlush event is not triggered when the transaction is allready open? https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/UnitOfWork.php#L290 It would help a lot developing listeners since this event is the mostly used one and since theres preFlush now it seems a logical solution if onFlush would be a start of transaction in general
