[DC-1040] allow queries with table joins across different databases

Thu, 17 Nov 2011 14:42:03 +0000

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:

************* 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.

[DC-1035] ORA-01791 due to bad driver name in Doctrine_Adapter_Oracle

Thu, 1 Sep 2011 09:31:24 +0000

When i execute this code:

 
$q = Doctrine_Query::create()
            ->from('AGENT ag')
            ->leftJoin('ag.CHANTIER_AGENT cag)
            ->orderBy('ag.nom')
            ->limit(10)
            ->execute();
$q2 = Doctrine_Query::create()
            ->from('AGENT ag')
            ->leftJoin('ag.CHANTIER_AGENT cag)
            ->orderBy('ag.nom')
            ->limit(10)
            ->execute();

Doctrine executes :

 
SELECT a.pk AS a__pk, a.ts AS a__ts, a.ck_agent AS a__ck_agent, a.matricule AS a__matricule, a.nom AS a__nom, 
a.prenom AS a__prenom, a.agent_maitrise AS a__agent_maitrise, c.pk AS c__pk, c.ts AS c__ts, c.ck_chantier_agent AS c__ck_chantier_agent, 
c.ek_chantier AS c__ek_chantier, c.fk_chantier AS c__fk_chantier, c.ek_agent AS c__ek_agent, c.fk_agent AS c__fk_agent 
FROM AGENT a 
LEFT JOIN CHANTIER_AGENT c ON a.ck_agent = c.ek_agent 
WHERE a.ck_agent IN (
SELECT a2.ck_agent FROM ( 
SELECT DISTINCT a2.ck_agent, a2.nom FROM AGENT a2 LEFT JOIN CHANTIER_AGENT c2 ON a2.ck_agent = c2.ek_agent ORDER BY a2.nom ) 
a2 WHERE ROWNUM <= 10) ORDER BY a.nom

SELECT a.pk AS a__pk, a.ts AS a__ts, a.ck_agent AS a__ck_agent, a.matricule AS a__matricule, a.nom AS a__nom, 
a.prenom AS a__prenom, a.agent_maitrise AS a__agent_maitrise, c.pk AS c__pk, c.ts AS c__ts, c.ck_chantier_agent AS c__ck_chantier_agent, 
c.ek_chantier AS c__ek_chantier, c.fk_chantier AS c__fk_chantier, c.ek_agent AS c__ek_agent, c.fk_agent AS c__fk_agent 
FROM AGENT a 
LEFT JOIN CHANTIER_AGENT c ON a.ck_agent = c.ek_agent 
WHERE a.ck_agent IN (
SELECT a2.ck_agent FROM ( 
SELECT DISTINCT a2.ck_agent FROM AGENT a2 LEFT JOIN CHANTIER_AGENT c2 ON a2.ck_agent = c2.ek_agent ORDER BY a2.nom ) 
a2 WHERE ROWNUM <= 10) ORDER BY a.nom

This causes "Oracle DB Error ORA-01791 not a SELECTed expression" because the sql query don't have a2.nom in SELECT DISTINCT and it's indispensable for ORDER BY a2.nom
The problem is caused by the variable $attributes in Doctrine_Adapter_Oracle :

 
protected $attributes = array(Doctrine_Core::ATTR_DRIVER_NAME    => "oci8",
                                  Doctrine_Core::ATTR_ERRMODE        => Doctrine_Core::ERRMODE_SILENT);

The problem is in Query.php line 1417 :

	if ($driverName == 'pgsql' || $driverName == 'oracle' || $driverName == 'oci' || $driverName == 'mssql' || $driverName == 'odbc') {

The driver name declared in Doctrine_Adapter_Oracle not in this conditional.
To resolve this we have to modify the declaration of $attributes in Doctrine_Adapter_Oracle to :

protected $attributes = array(Doctrine_Core::ATTR_DRIVER_NAME    => "oracle",
                                  Doctrine_Core::ATTR_ERRMODE        => Doctrine_Core::ERRMODE_SILENT);

An other problem is probably located at line 1409

 if (($driverName == 'oracle' || $driverName == 'oci') && $this->_isOrderedByJoinedColumn()) {

and 1497

        if (($driverName == 'oracle' || $driverName == 'oci') && $this->_isOrderedByJoinedColumn()) {

if don't correct the declaration of $attributes in Doctrine_Adapter_Oracle.

a2 )

The problem is in function _createLimitSubquery in Doctrine_Connection_Oracle :

 
                    $query= 'SELECT '.$this->quoteIdentifier('b').'.'.$column.' FROM ( '.
                                 'SELECT '.$this->quoteIdentifier('a').'.*, ROWNUM AS doctrine_rownum FROM ( '

                              ' ) ' . $this->quoteIdentifier('b') . ' '.
                              'WHERE doctrine_rownum BETWEEN ' . $min .  ' AND ' . $max;

Error occures, because table name is AGENT and Doctrine give the first letter of the table name for identifier.
To correct this. Use more than one letter in the quoteIdentifier.

 
                    $query = 'SELECT '.$this->quoteIdentifier('limb').'.'.$column.' FROM ( '.
                                 'SELECT '.$this->quoteIdentifier('lima').'.*, ROWNUM AS doctrine_rownum FROM ( '

[DC-1031] CLONE -Multiple connections and i18n (raised as unresolved - original ticket marked as resolved)

Wed, 28 Mar 2012 08:20:53 +0000

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"

[DC-972] MySQL field aliases with triple ticks

Wed, 16 Feb 2011 11:14:24 +0000

In revision 7691 something has happened. Ever since I updated my Doctrine to that revision all my queries having " ... fieldname AS aliasname ... " go crazy and make the PHP to throw an exception, like this:

'Doctrine_Connection_Mysql_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 't.`id`' in 'field list'. Failing Query:
"SELECT `t`.`id` AS `t_id`, `t`.```id``` AS `t0`, `t`.```name``` AS `t1`, `t`.`id` AS `t0`, `t`.`name` AS `t_1` FROM `territoryCombined` `t` ORDER BY `t`.`name` asc"'
in ...path here.../doctrine/lib/Doctrine/Connection.php:1082

The problem is that the DQL parser somewhere along the process encapsualtes aliases in ticks, but then it does it again in lib/Doctrine/Formatter.php : quoteIdentifier() , which is called in lib/Doctrine/Connection : quoteIdentifier() , which is called in lib/Doctrine/Query.php : processPendingFields() @ between lines 485 and 512. The problem is that by the time the alias name gets to line 507 it is already encapsualted in ticks, but it does it again. At the end we end up with ```alias``` , which is not good.

It only happens to aliases. If I say select('*') or select("t.id, t.name") then it executes properly. Only the aliases couse problems.

A test query:

$vTerritories = Doctrine_Query::create()
->select("t.id as territory_id, t.name as territory_name")
->from('TerritoryCombined t')
->orderBy('t.name asc')
->fetchArray();

MY PROPOSED PATCH:

If I change the Formatter::quoteIdentifier() to this:

public function quoteIdentifier($str, $checkOption = true)

{ $tmp = $this->conn->identifier_quoting; // I move up this line to here because I need it if ( (substr($str, 0, 1) == $tmp['start']) && (substr($str, -1) == $tmp['end']) ) return $str; // new line; is it already quoted? if yes, then don't do it again // the rest is unchanged }

then it works correctly. Please note I only tested that in MySQL, as we use MySQL in all our projects.

[DC-962] Broken logic when doctrine translates limit's into subqueries, with joins. (with patch)

Wed, 2 Feb 2011 10:19:59 +0000

Problem exists when Doctrine formulates a subquery to perform a limit when a join in included.

The problem is that the where clause that doctrine creates for the subquery (the WHERE IN clause) is inserted as the first where clause.
This will break the parameter duplicate done at Doctrine_Query_Abstract:969, as the order of the parameters is now wrong.

Consider:

 
select * from table
join metadata WITH c = ?
where a = ? and b = ?
limit 1

with parameters be (1, 2, 3)

Doctrine will translate this to

 
select * from table
join metadata WITH c = ?
where table.id IN (
    select id from table
    join metadata WITH c = ?
    where a = ? and b = ?
    limit 1
)
and a = ? and b = ?

Doctrine will duplicate the params (Doctrine_Query_Abstract:969) to (1, 2, 3, 1, 2, 3), but now they are in the wrong order completely.
They should be (1,1,2,3,2,3).

The easy fix is to move the limit subquery to the LAST where clause, which would reuslt in a query like so:

 
select * from table
join metadata WITH c = ?
where a = ? and b = ?
and table.id IN (
    select id from table
    join metadata WITH c = ?
    where a = ? and b = ?
    limit 1
)

Attached is a patch to fix this issue, along with a patch that fixes all unit tests referring to the old query format.

[DC-952] Non-Equal Nest Relations Not Working - from "Children" side

Thu, 24 Mar 2011 04:59:10 +0000

I've copy & pasted example from http://www.doctrine-project.org/projects/orm/1.2/docs/manual/defining-models/1_0#relationships:join-table-associations:self-referencing-nest-relations:non-equal-nest-relations .
I've created User backend module using doctrine:generate-admin backend User task. On how to reproduce the error:

1. Add 3 User objects (A,B,C)
2. Open generated edit form for User A.
3. Set User B as Children from Children list and Save
4. Set User B and C as Chidren from Children list and Save

As a result you will see only C set as Children, and strange situation in database :

UserReference Table:

parent_id | child_id
pk_B | pk_B (!!!)
pk_A | pk_C

doctrine executes next statement:

SELECT "p"."id", "p2"."name" AS "p2__name", "p2"."lang" AS "p2__lang"

This sql code produces next error

ORA-01791: not a SELECTed expression

Error occures, because (from ORACODE)

There is an incorrect ORDER BY item. The query is a SELECT DISTINCT query with an ORDER BY clause. In this context, all ORDER BY items must be constants, SELECT list expressions, or expressions whose operands are constants or SELECT list expressions

[DC-791] [PostgreSQL] In case model is build from existing database sequence name is invalid and doctrine throw exception

Wed, 25 Aug 2010 02:40:04 +0000

Firstly I created database directly in postgresql.
After that I generated schema from existsing database and after all i built model.

When I try to insert new record to database I received following error:

sequence "Category_id_seq" does not exist

In schema file sequence name is defined like this: sequence: '"Address_id_seq"'
There's are apostrophes and quotes.

In Category model file is same like above, apostrophes and quotes.

When I remove quotes from sequence in model files everything is ok and there're no problems with insert new row to database.

[DC-770] Result Cache

Tue, 29 Jun 2010 05:50:36 +0000

Doctrine result cache isn't working properly.

Here a simple example, when I'm calling query->execute (); parentProgram is related to a video.
Into the Doctrine_Query_Abstract.php file

line 1014 : I have just add some code to output data.
[code]
if ($cached === false)

{ // cache miss $stmt = $this->_execute($params); $this->_hydrator->setQueryComponents($this->_queryComponents); $result = $this->_hydrator->hydrateResultSet($stmt, $this->_tableAliasMap); $oVideo = $result[0]; echo "not cached "; var_dump (count ($oVideo->parentProgram->getReferences ())); $cached = $this->getCachedForm($result); $cacheDriver->save($hash, $cached, $this->getResultCacheLifeSpan()); }

else

{ $result = $this->_constructQueryFromCache($cached); $oVideo = $result[0]; echo "cached "; var_dump (count ($oVideo->parentProgram->getReferences ())); exit (0); }

[/code]

The output of a query execution (the first with an empty APC cache) with "useResultCache" is :

not cached int(1)
cached int(0)

The problem is coming from the serialize php function that can't serialize protected properties..
getReferences is a getter to a protected property.. So data result can't work properly.

A solution could be use __sleep function, and a public property that contain all important protected data.

[DC-701] Aggregates functions do not return proper values when using many relationships and limits

Mon, 1 Nov 2010 20:12:17 +0000

Hi All

I have encountered a problem that seems very core to the way that doctrine works – if you apply an aggregate function to a column in a table and then join to another table via a many relationship while also using a limit, like so:

$q = Doctrine_Query::create();
$q->from('Customer Customer'); 
$q->addSelect('COUNT(Customer.id) as COUNT_customer_id');
$q->addSelect('Customer_Order.id as order_id'); 
$q->leftJoin('Customer.Order Customer_Order'); // Many relationship here
$q->limit(20);

It produces this correct DQL:

SELECT COUNT(Customer.id) as COUNT_customer_id, Customer_Order.id as order_id 
FROM Customer Customer 
  LEFT JOIN Customer.Order Customer_Order 
LIMIT 20

However the SQL it produces will not return an accurate count – the count is restricted by the limit:

SELECT COUNT(p.id) AS p__0, p2.id AS p2__1 
FROM product_customers p 
  LEFT JOIN product_orders p2 ON p.id = p2.customer_id 
WHERE p.id IN ('1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20')

This produces a count of 21 instead of what it should be (1000).

The reason for this is because Doctrine's internal functionality does an intermediary query where it gets gets the ids needed from the customer table in order to use them as the IN portion of the constraints on the final query – like so:

SELECT DISTINCT p3.id FROM product_customers p3 LIMIT 20

It may seem strange that I am applying a limit to a query which will aggregate to 1 to row . In the actual queries that alerted me to this problem I am using a group by. The reason I am not reporting this bug with a group by in my example however is that you can not use a group by with a many relationship and a limit in doctrine 1.2.2 as it works currently (see bug: ~~DC-594~~). However I am personally able to use a limit with a group by and many relationship since I am using a version of the code I patched my self to repair bug ~~DC-594~~.

Here is my sample schema in case its helpful.

detect_relations: false
package: Example
options:
  type: INNODB
  charset: utf8
Order:
  tableName: orders
  columns:
    order_id:
      type: integer(4)

      notnull: true
    customer_id:
      type: integer(4)

[DC-665] Named parameters doesn't work on MSSQL anymore

Wed, 22 Sep 2010 00:55:15 +0000

After upgrading to Doctrine 1.2.2 queries with named arguments doesn't work anymore.
Whenever querying like
$query = Doctrine_Query::create();
$customer = $query->from('Customers')
->where("id = :id"
, array('id'=>$user['customer_id']))
->fetchOne(array(), Doctrine::HYDRATE_ARRAY);

I get the error
SQLSTATE[HY000]: General error: 10007 Incorrect syntax near ':'. [10007] (severity 5)

If changing the query to
$query = Doctrine_Query::create();
$customer = $query->from('Customers')
->where("id = ?"
, array($user['customer_id']))
->fetchOne(array(), Doctrine::HYDRATE_ARRAY);
it works fine.
Testing with MySQL works fine, so it seems contained to MSSQL

[DC-627] Work on link-table and leftJoin

Tue, 13 Apr 2010 05:07:32 +0000

Looking at the attachment to see the little schema.
Tree table : items, items_children and children.

The link-table items_children is here to create a many-to-many relationships between Items and Children.

So, after configure the YAML and generated Models.
We can do something like that :

$query = Doctrine_Query::create ()
->select ("items.title, children.title")
->from ("Item items")
->leftJoin ("item.children children");
$items = $query->execute ();

$items //An array of items
$items[0]->title //A string
$items[0]->children //An array of children

The SQL Output of the query is :

SELECT `i`.`id_item` AS `i_id_item`, `i`.`title` AS `ititle`, `c`.`id_child` AS `cid_child`, `c`.`title` AS `c_title` FROM `items` `i` LEFT JOIN `items_children` `i2` ON (`i`.`id_item` = `i2`.`id_item`) LEFT JOIN `children` `c` ON `i2`.`id_child` = `c`.`id_child`

All array are order by something, in this case it's a natural order which come from the items_children order into database.

Now, I want to apply a condition, or a filter on the items_children table.
If I translate my demand to SQL Query :

SELECT `i`.`id_item` AS `i_id_item`, `i`.`title` AS `ititle`, `c`.`id_child` AS `cid_child`, `c`.`title` AS `c_title` FROM `items` `i` LEFT JOIN `items_children` `i2` ON (`i`.`id_item` = `i2`.`id_item`) LEFT JOIN `children` `c` ON `i2`.`id_child` = `c`.`id_child` ORDER BY `c1`.`index`

Or something crazy :

SELECT `i`.`id_item` AS `i_id_item`, `i`.`title` AS `ititle`, `c`.`id_child` AS `cid_child`, `c`.`title` AS `c_title` FROM `items` `i` LEFT JOIN `items_children` `i2` ON (`i`.`id_item` = `i2`.`id_item`) LEFT JOIN `children` `c` ON `i2`.`id_child` = `c`.`id_child` WHERE `c1`.`index` > 2

But how can I do that with DQL ? Because I have no access to the Link-table.

Link-Table are use to create many-to-many, that could be OOP array. So we have to be allowed to add "index" to order the result. Also, we have to be allowed to add condition on this tables, like "datePromote" or simply "enabled".

The solution should be on the following DQL Query :

$query = Doctrine_Query::create ()
->select ("items.title, children.title")
->from ("Item items")
->leftJoin ("item.children children")
->leftJoin ("ItemsChildren link_table")
->orderBy ("link_table.index")
$items = $query->execute ();

But the SQL Output is :

SELECT `i`.`id_item` AS `i_id_item`, `i`.`title` AS `ititle`, `c`.`id_child` AS `cid_child`, `c`.`title` AS `c_title` FROM `items` `i` LEFT JOIN `items_children` `i2` ON (`i`.`id_item` = `i2`.`id_item`) LEFT JOIN `children` `c` ON `i2`.`id_child` = `c`.`id_child`, `items_children` `i3` ORDER BY `i3`.`index`

To conclude, it's a blocker problem. Because I can't use a standard DB schema.

[DC-313] Ordering m2m relationship with column from related table (with orderBy option)

Fri, 18 Feb 2011 03:32:42 +0000

I find no way to define automatic orderBy in m2m relations with column not from reference table, but actual related table.

E.g. BlogPost <= m2m through BlogPostCategory => BlogCategory
I need BlogPost->Categories ordered by BlogCategory.name

class BlogPost extends Doctrine_Record
{
    public function setTableDefinition()
    {
        $this->hasColumn('title', 'string', 128);
        $this->hasColumn('content', 'string');
    }
    
    public function setUp()
    {
        $this->hasMany('BlogCategory as BlogCategories', array('local' => 'id_blog_post', 'foreign' => 'id_blog_category', 'refClass' => 'BlogPostCategory', 'orderBy' => 'name'));        
    }
}

class BlogCategory extends Doctrine_Record
{
    public function setTableDefinition()
    {
        $this->hasColumn('name', 'string', 128);
    }
    
    public function setUp()
    {
        $this->hasMany('BlogPost as BlogPosts', array('local' => 'id_blog_category', 'foreign' => 'id_blog_post', 'refClass' => 'BlogPostCategory'));
    }
}

class BlogPostCategory extends Doctrine_Record
{
    public function setTableDefinition()
    {
        $this->hasColumn('id_blog_post', 'integer', null, array('primary' => true));
        $this->hasColumn('id_blog_category', 'integer', null, array('primary' => true));
    }
    
    public function setUp()
    {
        $this->hasOne('BlogPost', array('local' => 'id_blog_post', 'foreign' => 'id', 'onDelete' => 'CASCADE'));
        $this->hasOne('BlogCategory', array('local' => 'id_blog_category', 'foreign' => 'id', 'onDelete' => 'CASCADE'));
    }
}

The resulting query contains doubled 'name' column in ORDER BY clause, both from reference table and related table, e.g. ORDER BY t2.name, t3.name

I tried putting the following code in BlogCategory::setTableDefinition() instead of attribute in relation definition in BlogPost record:

$this->option('orderBy', 'name');

but the result was the same.

Maybe I'm doing something wrong? Is there a possibility to define an alias, where to get column name from - in orderBy attribute?

Thanks in advance.
