我正在通过 MySQL 服务器 5.5.28 使用与 Propel 1.6.7 集成的 Symfony 2.1.6 框架作为数据库 ORM，我在将数据库排序规则设置为utf8_unicode_ci.

我的app/config/config.yml：

...
propel:
    dbal:
        driver:               %database_driver%
        user:                 %database_user%
        password:             %database_password%
        dsn:                  "%database_driver%:host=%database_host%;dbname=%database_name%;charset=%database_charset%"
        options:
            MYSQL_ATTR_INIT_COMMAND: "SET NAMES utf8 COLLATE utf8_unicode_ci"
        attributes:           {}

（参数已经在app/config/parameters.yml中定义）

没有options它可以工作，但会出现字符集问题（MySQL 默认为utf8_general_ci排序规则，但数据库模式是用 定义的utf8_unicode_ci）。如果我options像上面那样使用 Propel/Symfony 会引发一堆异常：

我知道我可以更改my.cnf以直接从服务器配置定义 MySQL 默认排序规则，但我需要在运行时设置它......我错过了什么吗？我应该如何MYSQL_ATTR_INIT_COMMAND在app/config/config.yml中设置？

如果你在这里看到源代码，

$value = $optiondata['value']; // this is line no 275
if (is_string($value) && strpos($value, '::') !== false) {
    if (!defined($value)) {
       throw new PropelException("Invalid PDO option/attribute value specified: ".$value);
    }
    $value = constant($value);
}

它期望选项数据中有一个“值”键，所以试试这个

propel:
    dbal:
        driver:               %database_driver%
        user:                 %database_user%
        password:             %database_password%
        dsn:                  "%database_driver%:host=%database_host%;dbname=%database_name%;charset=%database_charset%"
        options:
            MYSQL_ATTR_INIT_COMMAND: { value: "SET NAMES utf8 COLLATE utf8_unicode_ci" }
        attributes:           {}

或者

您还可以定义必须在连接打开后立即执行的查询

propel:
    dbal:
        default_connection:         default
        connections:
            default:
                # ...
                options:
                    ATTR_PERSISTENT: false
                attributes:
                    ATTR_EMULATE_PREPARES: true
                settings:
                    charset:        { value: UTF8 }
                    queries:        { query: 'INSERT INTO BAR ('hey', 'there')' }

关于您更改 my.cnf 的观点，如果仅您要使用的数据库需要特定的排序规则设置，那么我认为最好在创建数据库时使用命令“ create database db_name CHARACTER SET utf8 ”覆盖排序规则设置COLLATE utf8_unicode_ci " 而不是通过编辑 my.cnf 来全局更改它
