Doctrine querybuilder DATE_FORMAT无效

Question

我在createQueryBuilder中遇到DATE_FORMAT的一些问题

我的代码:

$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();

但我得到了

 [Doctrine\ORM\Query\QueryException]                                              
 [Syntax Error] line 0, col 7: Error: Expected known function, got 'DATE_FORMAT'

我搜索了一些链接并找到一些解释它应该以这种方式工作,但对我来说,它看起来像我做错了.

Answer 1

DATE_FORMAT 随着一堆Mysql函数在Doctrine中无法直接使用.

要使用它们,您可以创建自己的扩展或添加类似的扩展beberlei/DoctrineExtensions,然后将相应的功能添加到您的学说包配置中

doctrine:
    dbal:
        ....
    orm:
        ....
        dql:
            string_functions:
                DATE_FORMAT: DoctrineExtensions\Query\Mysql\DateFormat

Answer 2

Symfony 5 答案

跑步

composer require beberlei/doctrineextensions

加入

配置/包/doctrine.yaml

doctrine:
    orm:
        dql:
            datetime_functions:
                DATE_FORMAT: DoctrineExtensions\Query\Mysql\DateFormat

其他日期时间函数也是如此：

doctrine:
    orm:
        dql:
            datetime_functions:
                DATE_FORMAT: DoctrineExtensions\Query\Mysql\DateFormat
                DAY: DoctrineExtensions\Query\Mysql\Day
                MONTH: DoctrineExtensions\Query\Mysql\Month
                YEAR: DoctrineExtensions\Query\Mysql\Year
