php - Doctrine querybuilder DATE_FORMAT not working

Question

I'm having some problems with DATE_FORMAT inside a createQueryBuilder

My code:

$qb7Days = $repo->createQueryBuilder('R')
        ->select( 'R.createdAt' )
        ->where( "DATE_FORMAT(R.createdAt, '%Y-%m-%d') = :afterDays" )
        ->andWhere( 'R.cCurrentReviewState = :state' )
        ->andWhere( 'R.reminder = :reminder' )
        ->setParameter( 'afterDays', $after7Days )
        ->setParameter( 'state',  $oReviewStateNotVerified ) // not_verified
        ->setParameter( 'reminder',  0 ) // never sent any reminder
        ->orderBy( 'R.id', 'ASC' )
        ->getQuery();

But im getting

 [DoctrineORMQueryQueryException]                                              
 [Syntax Error] line 0, col 7: Error: Expected known function, got 'DATE_FORMAT'

I've searched some links and find some explain that it should work this way, but for me it looks like im doing something wrong.

Answer 1

DATE_FORMAT along with a bunch of Mysql function are not directly available in Doctrine.

To use them you can either create your own or add an extension like beberlei/DoctrineExtensions and then add the respective function to your doctrine bundle config like

doctrine:
    dbal:
        ....
    orm:
        ....
        dql:
            string_functions:
                DATE_FORMAT: DoctrineExtensionsQueryMysqlDateFormat
