问题描述

我在 createQueryBuilder 中的 DATE_FORMAT 有一些问题

I'm having some problems with DATE_FORMAT inside a createQueryBuilder

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();

但是我得到了

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

我搜索了一些链接并找到了一些说明它应该以这种方式工作，但对我来说似乎我做错了什么.

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.

推荐答案

DATE_FORMAT 连同一堆 Mysql 函数在 Doctrine 中不直接可用.

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

要使用它们，您可以创建自己的或添加扩展程序，例如 beberlei/DoctrineExtensions 然后将相应的功能添加到您的学说包配置中，如

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
