I used to work with a single database named "doctrine". The query was working properly.

I then decided to use 2 databases so I got my schema like this:

connection: doctrine

Category:
actAs:
I18n:
actAs:
Sluggable:
fields: [name]
Timestampable: ~
fields: [name, description]
columns:
id: ~
name:
type: string(255)
notnull: true
description: string

User:
connection: second
columns:
id: ~
name:
type: string(255)
notnull: true

I did setup my connections in config/databases.yml this way:

all:
doctrine:
// ....
second:
// ....

build-model, build-forms, build-filters and cc got ran. But now, I got an exception saying the "Translation" relation doesn't exist. The Base Models include correctly the bindComponent line:

Doctrine_Manager::getInstance()->bindComponent('Category', 'doctrine');

For now, I managed to kind of fixing it with simply swapping the databases order in my config/databases.yml and it's now working again perfectly.

I forgot to mention that in the CategoryTable when i call $this->getConnection()->getName(), it outputs "second"

I'm currently working on a project which relies upon several databases declared in databases.yml in symfony 1.4.8.

I was facing an issue that has already been raised by other people, namely that you can't join tables which reference each other among different mysql databases.

I've dug a bit in the Doctrine_Query class and came to a solution that is acceptable for us, and allows now to make joins accross databases. Description follows :

first change is in the Doctrine_Core class, that gets stuffed with a new constant :
const ATTR_DATABASE_NAME = 0x1DB;

this constant allows us to add a new attribute to the databases.yml file as in :
gesdoc:
class: sfDoctrineDatabase
param:
dsn: mysql:host=127.0.0.1;dbname=gesdoc
username: root
password:
attributes:

1. ************* NEW ATTRIBUTE BELOW ************
   database_name: gesdoc
   default_table_collate: utf8_general_ci
   default_table_charset: utf8

after that, a few changes have been done in the Doctrine_Query class which is attached to this issue for the sake of readability.

This may not be optimal, and probably need some regression testing, but it is currently working fine on our test server.

after this is done, I was able to issue queries like the following :
$x = DocumentTable::getInstance()->createQuery('d')
->distinct()
->leftJoin('d.Travail t')
->leftJoin('t.CdcIndInt ci')
->leftJoin('ci.CdcIndExt ce')
->leftJoin('ce.Cahierdescharge cdc')
->where('cdc.cdc_chro = ?', $cdc_chro)
->addWhere('d.id != ?', $document_id)
->execute();

where the referenced tables are in different databases. The necessary object binding has been done in every model class following the paradigm :

Doctrine_Manager::getInstance()->bindComponent('CdcIndInt ', 'gescdc');
abstract class BaseCdcIndInt extends sfDoctrineRecord
{
...
}

I don't know if this description is clear enough, so let me know if something is missing/wrong.

This is the doc exemple on column aggregation inheritance :

Entity:
columns:
username: string(20)
password: string(16)
created_at: timestamp
updated_at: timestamp

User:
inheritance:
extends: Entity
type: column_aggregation
keyField: type
keyValue: 1

Group:
inheritance:
extends: Entity
type: column_aggregation
keyField: type
keyValue: 2

But the keyField (type) is created as VARCHAR(255) so PostgreSQL return an error on applying inheritance condition :

SQLSTATE[42883]: Undefined function: 7 ERROR: operator does not exist: character varying = integer
LINE 1: ...D s.application = 'frontend' AND s.lft = 1) AND (s.type = 2)
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.

I found this with symfony sfFilebasePlugin on sfFilebase:create-root task.

if you set prefix to "xyz_%s" and have the model "BackgroundColor" it will become the table => "xyz_background_color"
if you have the table "xyz_background_color" with unknown model and create the the model from the table, you will get => "XyzBackgroundColor".

The fix (diff):

> $tablePrefix = $manager->getAttribute(Doctrine_Core::ATTR_TBLNAME_FORMAT);

I'm using doctrine and some of mysql's spatial functions. I need to specify spatial index for my tables.
My declaration looks like:

Geometry:
tableName: geometry
options:
type: MyISAM
collate: utf8_unicode_ci
charset: utf8
columns:
id:
type: integer(4)
primary: true
autoincrement: true
geometry:
type: geometry
notnull: true
indexes:
geometry:
fields:

• geometry
  type: spatial

Exporting this definitions throws an exception: Unknown type spatial for index geometry_idx

When using the Doctrine_Record::option('orderBy', ...) feature on a table definition, where that table is the target of a many-to-many join, the specified orderBy columns are applied to the relation table's alias. So for example, given the following definitions:

class User extends Doctrine_Record {
  public function setTableDefinition() {
    $this->hasColumn('uid', 'integer', null, array('primary' => true));
    $this->option('orderBy', 'uid');
  }

  public function setUp() {
    $this->hasMany('Group as groups', array('refClass' => 'UserGroup', 'local' => 'user_uid', 'foreign' => 'group_id'));
  }
}

class Group extends Doctrine_Record {
  public function setTableDefinition() {
    $this->hasColumn('gid', 'integer', null, array('primary' => true));
  }

  public function setUp() {
    $this->hasMany('User as users', array('refClass' => 'UserGroup', 'local' => 'group_gid', 'foreign' => 'user_id'));
  }
}

class UserGroup extends Doctrine_Record {
  public function setTableDefinition() {
    $this->hasColumn('user_uid', 'integer', null, array('primary' => true));
    $this->hasColumn('group_gid', 'integer', null, array('primary' => true));
  }

  public function setUp() {
    $this->hasOne('User as user', array('local' => 'user_uid', 'foreign' => 'uid'));
    $this->hasOne('Group as group', array('local' => 'group_gid', 'foreign' => 'gid'));
  }
}

the following queries:

$query = Doctrine_Query::create()
  ->select('u.*')
  ->from('User u')
  ->leftJoin('u.groups g WITH g.gid=?', 1);
echo $query->getSqlQuery() . "\n";

$query = Doctrine_Query::create()
  ->select('g.*')
  ->from('Group g')
  ->leftJoin('g.users u WITH u.uid=?', 1);
echo $query->getSqlQuery() . "\n";

will output the following:

SELECT u.uid AS u__uid FROM user u LEFT JOIN user_group u2 ON (u.uid = u2.user_uid) LEFT JOIN group g ON g.gid = u2.group_id AND (g.gid = ?) ORDER BY u.uid
SELECT g.gid AS g__gid FROM group g LEFT JOIN user_group u2 ON (g.gid = u2.group_gid) LEFT JOIN user u ON u.uid = u2.user_id AND (u.uid = ?) ORDER BY u.uid, u2.uid

The orderBy option() call is applied to the User definition. The SQL for the first query is correct (where User is on the left side of the join). The SQL for the second query (where User is on the right-most side of the join), however, is obviously incorrect (UserGroup doesn't even have a uid column). Basically, User's orderBy option is being applied to both the User table and its respective reference table, UserGroup, when it is the target of a join.

After digging through the source for a while, I believe I've come up with a patch for this issue (which should be checked by someone more knowledgeable of Doctrine's internals). Basically, in the Doctrine_Query::buildSqlQuery() function, a call is made to Doctrine_Relation::getOrderByStatement() with the reference table (UserGroup)'s alias (u2), which in turn makes a call to Doctrine_Table::getOrderByStatement() on the referenced table (User), filling in the ORDER BY clause with User columns using UserGroup's alias. My solution was to reorder the logic so that the test for a reference class is made before the initial call to getOrderByStatement() is made. It seems to work against my test case and the test cases in the repository. I'll post my patch momentarily.

This bug was first mentioned in the comments in DC-313, but the original ticket comes across as more of a feature request for the hasMany() orderBy feature.
