A DQL query that contains an arithmetic expression like 'a/(b*c)' will be compiled to 'a/b*c' in SQL and therefore the result of '100/(2*2)' will be 100, instead of 25.

Note: I have tested it by mysql only

Edit: moved the bug to the dbal project, please delete this or set as invalid, new bug:

http://www.doctrine-project.org/jira/browse/DBAL-392

------------------------------------------------------

These are the steps I've tried to reproduce the problem:

• composer create-project symfony/framework-standard-edition path/ 2.1.3
• edited parameters for mysql db
• created attached 'Post' entity (note the parent/children fields)
• updated schema with doctrine:schema:create

I see that the foreign key in phpmyadmin is correctly set to Post.id which is correct.

Now:

• created another entity 'Argument'
• moving the children field from 'Post' to 'Argument' removing setters getters into 'Post' and changing target entity field accordingly
• Updated DB schema (doctrine:schema:update --force)

The situation is now the one you can find in Post2 and Argument attachments.

The problem is that now, the foreign key in Post field it's still on Post.id and not on Argument.id and schema:update says the DB is in sync with the metadata.

Manually deleting the foreign key and running schema:update makes the key being correctly created into Argument.id

Using symfony2 command doctrine:schema:create the tables and Varchar fields are Collate/Charset are not inherited from database. I changed MySQL defaults to latin1/latin1_general_ci; The doctrine:database:create works; but tables and fields don't. So I found there is a code on MySqlPlataform.php:

if ( ! isset($options['charset']))

if ( ! isset($options['collate']))

$query .= 'DEFAULT CHARACTER SET ' . $options['charset'];
$query .= ' COLLATE ' . $options['collate'];

So if you don't pass collate and charset as entity options, it will put utf8 and utf8_unicode_ci instead of dabatase default charset.

My suggestion is to change a little bit to:

if (isset($options['charset']))

if (isset($options['collate']))

i searched a lot for this

there is no way to set the collate of table fields to for ex. utf8_persian_ci in doctrine settings

Generation of any SQL command to the database (From entities or migration versions) does not quote all the reserved keywords (For example a fieldname `right`.

Simple fix that always works: double-quote dbname, schemaname and fieldname

e.g "dbsecurity"."userschema"."users" or "tblusers"

MySQL : use the ` sign.

e.g `security`.`users` or `tblusers` (No support for schemas since I last checked some time ago)

For example:

$queryBuilder
    ->select('DISTINCT c.id')
    ->from('Campaigns', 'c')
    ->leftJoin('c', 'CampaignOperations', 'od', 'od.campaignId = c.id AND od.operation = :operation')
    ->from('BannerGroups', 'bg')
    ->innerJoin('bg', 'BannerGroupStrategies', 'bgs', 'bgs.groupId = bg.id AND bgs.advSystem = :system')
    ->where('bg.campaignId = c.id');

Builded the query:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation)
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system), 
  BannerGroups bg
  WHERE (bg.campaignId = c.id)

If this query execute on mysql, we get error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'bg.id' in 'on clause'

Expected result:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation),
  BannerGroups bg
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system)
  WHERE (bg.campaignId = c.id)

Regression after patch https://github.com/doctrine/dbal/pull/175

When trying to use the mysql assignment operator in a native query one gets an exception as SqlParserUtils does not qualify the character after the : as being part of a valid parameter value.

Undefined index: in vendor/doctrine/dbal/lib/Doctrine/DBAL/SQLParserUtils.php line 156 (uncaught exception)

A simple example is
$rsm = new ResultSetMapping();
$rsm->addScalarResult('rank', 'rank');
$qry = $em->createNativeQuery("
SELECT (@rank := 1) AS rank
");
$result = $qry->getResult(Query::HYDRATE_ARRAY);

Or a more complicated example is (similar to actual use):

$rsm = new ResultSetMapping();
$rsm->addScalarResult('rank', 'rank');
$qry = $em->createNativeQuery("
SELECT rank FROM
(SELECT (@rank := @rank +1) AS rank FROM (SELECT @rank :=0) rnk2) rnk1
");
$result = $qry->getResult(Query::HYDRATE_ARRAY);

I have attached quick-fix patch, but it looks like the getPlaceholderPositions method is wanting something better overall (due to the TODO comment in it).
