[DDC-1563] Result cache for repository queries

Sun, 26 Aug 2012 19:34:52 +0000

Many related "standing data" tables are very static and seldom change. There should be a metadata config to enable result cache for ALL repository operations.

@entity(resultCache=@cache(ttl=3600))

[DDC-2208] CASE WHEN ... WHEN doesn't work

Tue, 8 Jan 2013 21:07:23 +0000

Having the following part in select DQL throws an exception.

SUM(CASE
            WHEN c.startDate <= :start THEN c.endDate - :start
            WHEN c.endDate >= :end THEN :end - c.startDate
            ELSE 0
            END)

exception:

[Syntax Error] line 0, col 124: Error: Expected Doctrine\ORM\Query\Lexer::T_ELSE, got '-'

It seems that it's failing inside the second THEN

This one also seems to fail:

SUM(CASE
            WHEN c.startDate <= :start THEN (c.endDate - :start)
            WHEN c.endDate >= :end THEN (:end - c.startDate)
            ELSE 0
            END)

exception:

[Syntax Error] line 0, col 60: Error: Unexpected '('

Another one:

SUM(CASE
                WHEN c.startDate <= :start THEN c.endDate - :start
                WHEN c.endDate >= :end THEN :end - c.startDate
                ELSE 0
                END) = :result FROM ...

exception:

[Syntax Error] line 0, col 60: Error: Expected Doctrine\ORM\Query\Lexer::T_FROM, got '='

[DDC-2351] Entity Listener vs. Event Listener

Fri, 15 Mar 2013 08:45:49 +0000

Entity Listener and Event Listener don't get same events. An example is the onFlush event, which Entity Listener doesn't get. Why are both listeners receiving different events and not same events?

For consistency I'd like to see that both get same events - if I understand the purpose of Entity Listener correctly: it should be an alternative to Event Listener with same functionality but is bound to an entity.

[DDC-2429] Association-Override Problem in XSD Mapping?

Mon, 13 May 2013 16:26:27 +0000

From a mailinglist entry:

I use Doctrine 2.3 in Symfony 2.1.8

I'm using association-overrides in the XML format between several entities. Eclipse shows up several errors.

The first error message is shown in every Doctrine file when I declare the file format as such (for example: https://github.com/thewholelifetolearn/Social-Library/blob/master/src/SocialLibrary/ReadBundle/Resources/config/doctrine/GraphicNovel.orm.xml )

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                  http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

Eclipse shows this error :
White spaces are required between publicId and systemId

The error points to the "doctrine-mapping" line

The second error comes up when I change the doctype to (file example: https://gist.github.com/thewholelifetolearn/5462057 ):

<?xml version="1.0" encoding="UTF-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
                  https://raw.github.com/doctrine/doctrine2/master/doctrine-mapping.xsd">

But then this error is shown:
cvc-complex-type.2.4.b: The content of element 'association-overrides' is not complete. One of '

{"http://doctrine-project.org/schemas/orm/doctrine-mapping":association-override, WC[##other:"http://doctrine-project.org/schemas/orm/doctrine-mapping"]}

' is expected.

The error points on "<association-overrides>" in Novel.orm.xml (line 8)

Could someone explain me the errors that show up? The first error doesn't seem to disturb Symfony2 but the second messes around the console commands. But it still generates the database.

[DDC-1373] Map file with specific class

Tue, 14 Feb 2012 22:53:37 +0000

Hi there,
AbsractFileDriver is using the filename to know the managed class.

It's a cool feature because it's allow loading on-demand.
The problem is, that the filename must be the name of the Class.

It should be great to be able to manually map XML/YAML File description to a Class, like :
$drivers->addMappingFile ( array ( "filename" => "class", "filename2" => "class2") );

This feature is simple to implement, just add a new array inside AbsractFileDriver to know the mapping.
When using the current method with addPaths, parse the folder to get traditional XML/YAML file where filename corresponding to classname and add it to the mapping array.

AbsractFileDriver->getAllClassNames () just return value of mapping array.
The mapping array is store inside cache.

With this new feature, it allow developers to create a pretty folder that contains entities mapping.

Armetiz.

[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-1889] generate persisters

Mon, 22 Oct 2012 01:02:08 +0000

I'm not sure if this is really possible..

but to improve performance we should consider generate custom entity persisters.

Now entity persister are not cached,
if we generate it, we can create performance improvement in hidrators, avoiding checks and sql generation every time that an persister is called.

[DDC-2459] ANSI compliant quote strategy.

Fri, 17 May 2013 17:35:45 +0000

In order to simplify and speed up the sql generation
an ANSI quote strategy would be useful.

The implementation would be something like :

<?php
class AnsiQuoteStrategy implements \Doctrine\ORM\Mapping\QuoteStrategy
{
    /**
     * {@inheritdoc}
     */
    public function getColumnName($fieldName, ClassMetadata $class, AbstractPlatform $platform)
    {
        return $class->fieldMappings[$fieldName]['columnName'];
    }

    /**
     * {@inheritdoc}
     */
    public function getTableName(ClassMetadata $class, AbstractPlatform $platform)
    {
        return $class->table['name'];
    }

    /**
     * {@inheritdoc}
     */
    public function getSequenceName(array $definition, ClassMetadata $class, AbstractPlatform $platform)
    {
        return $definition['sequenceName'];
    }

    /**
     * {@inheritdoc}
     */
    public function getJoinColumnName(array $joinColumn, ClassMetadata $class, AbstractPlatform $platform)
    {
        return $joinColumn['name'];
    }

    /**
     * {@inheritdoc}
     */
    public function getReferencedJoinColumnName(array $joinColumn, ClassMetadata $class, AbstractPlatform $platform)
    {
        return $joinColumn['referencedColumnName'];
    }

    /**
     * {@inheritdoc}
     */
    public function getJoinTableName(array $association, ClassMetadata $class, AbstractPlatform $platform)
    {
        return $association['joinTable']['name'];
    }

    /**
     * {@inheritdoc}
     */
    public function getIdentifierColumnNames(ClassMetadata $class, AbstractPlatform $platform)
    {
        return $class->identifier;
    }

    /**
     * {@inheritdoc}
     */
    public function getColumnAlias($columnName, $counter, AbstractPlatform $platform, ClassMetadata $class = null)
    {
        return $platform->getSQLResultCashing($columnName . $counter);
    }
}
