我想在我的Symfony应用程序中的where条件中使用德语变音符号过滤一个表,但奇怪的是它不起作用。
代码:
$queryBuilder = $this->entityManager
->createQueryBuilder()
->select('p')
->from('AppBundle:Tablename', 'p');
$queryBuilder->andWhere('p.firm like :searchTerm');
$parameters['searchTerm'] = '%'.$data['search'].'%';
$dql = $this->entityManager
->createQuery($queryBuilder->getDql())
->setParameters($parameters);
数据:
MySQL [mydb_de]> SELECT firm FROM tablename WHERE firm LIKE '%bar%';
+---------+
| firm |
+---------+
| föo&bar |
+---------+
1 rows in set (0.01 sec)
MySQL [mydb_de]> SELECT firm FROM tablename WHERE firm LIKE '%föo%';
+---------+
| firm |
+---------+
| föo&bar |
+---------+
1 row in set (0.01 sec)
我在搜索bar
时收到了预期的结果,但搜索föo
时没有结果。

我试图将config.yml(doctrine.dbal.charset
)中的字符集切换为latin1
和latin1_swedish_ci
而没有运气。
我启用了日志记录(doctrine.dbal.logging
),在Profiler中找到了查询并检查了searchTerm,我觉得很好看:
我们有许多国家/地区的数据库,其中一些使用utf8,但其他国家/地区不使用。据我所知,我们的德国数据库不使用utf8,并且在不久的将来无法改变它
Symfony-Version:3.4.6
主义 - 版本:2.5.14
MySQL版本:5.5.47
有人知道可能导致这种情况的原因吗?
答案 0 :(得分:2)
Symfony for Doctrine的默认配置如下:
doctrine:
dbal:
# configure these for your database server
driver: 'pdo_mysql'
server_version: '5.7'
charset: utf8mb4
url: '(your database url)'
此配置指定数据库表应使用interclassment utf8mb4
。准确地使用特殊字符(如果你不使用mariadb,也可以使用复杂的utf-8字符(f.i.emojis))。
