Symfony2: deleted property still used in query

Question

I deleted a property (teaser) from an enitiy (sale). I used the CLi to update the database & entites:

$ php app/console doctrine:schema:update --complete --force
$ php app/console doctrine:generate:entities Our --no-backup
$ php app/console doctrine:cache:clear-metadata
$ php app/console doctrine:cache:clear-result

And i cleared the cache:

$ php app/console cache:clear --no-optional-warmers --no-warmup

Now i have a query created by query builder:

$qb = $this->createQueryBuilder('s');
$q = $qb
    ->select('s.id')
    ->leftJoin('s.bills','b')
    ->where('b.paid = true')
    ->getQuery()
    ->getResult();

This throws an error becuas eit generates a select statement that includes the old property:

Column not found: 1054 Unknown column 's0_.teaser' in 'field list'

I tried to understand how Doctrine executes the query but failed to find the source of the problem. Does anyone have any clues?

UPDATE: I took the DQL from the query, generated by the querybuilder and then used that to create a new Query. Same Error. Then i changed one word in the DQL from uppercae to lowercase (LEFT is now Left) and that one executed just fine.

$q = $this->getEntityManager()
->createQuery('SELECT s,b FROM Our\BuyBundle\Entity\Sale s Left JOIN s.bills b WHERE s.id IN (:randomIds)')
->setParameter('randomIds', $allSaleIds);

So it seems the DQL Statement is cached somewhere, Using the DQL as a hash to get the corresponding SQL Statement. I still can't quite figure out where and how to clear that cached Information. Especially given the fact that i deleted all content in the app/cache folder as well.

UPDATE2: Found the Solution. Had to clear the APC Cache manually since the console can't do that. So the Solution would be:

$ php app/console doctrine:cache:clear-query

And if that doesn't work, clear your APC Cache.

Answer 1

My Problem was the APC Cache.

I could not clear the query-cache in CLI (app/console) since the console can't (or is not allowed to) clear the APC Cache. So i had to clear the APC Cache manually.

Solution is:

$ php app/console doctrine:cache:clear-result

And if that doesn't work, clear the APC Cache (or whatever cache you use) manually.
