原则ORM定制列排序规则
我正在Doctrine文档中设置自定义列排序规则：
I'm trying to set custom column collation as in Doctrine documentation:
- http://doctrine-dbal.readthedocs.org/en/latest/reference/schema-representation.html 和
- http： //doctrine-orm.readthedocs.org/en/latest/reference/annotations-reference.html
- http://doctrine-dbal.readthedocs.org/en/latest/reference/schema-representation.html and
- http://doctrine-orm.readthedocs.org/en/latest/reference/annotations-reference.html
使用
@ ORM\Column（name =body，type =string，length = 140，options = {customSchemaOptions= { collate=utf8mb4_unicode_ci}}）
但是当我更新架构时，它总是返回到utf8_unicode_ci（手动设置时）例如）。任何想法？
but when I update the schema it always goes back to utf8_unicode_ci (when I set it manually for example). Any ideas?
如果您（或其他人）仍然需要，现在已添加，请参阅 http://doctrine-orm.readthedocs.org/en/latest/ reference / annotations-reference.html＃annref-column
This has been added by now if you (or someone else) still need, see http://doctrine-orm.readthedocs.org/en/latest/reference/annotations-reference.html#annref-column
示例：
/**
* @var string
*
* @ORM\Column(type="string", length=64, nullable=false, options={"collation":"utf8_bin"})
*/
private $code;
现在，所有常用数据库驱动程序都支持。
This is supported by all common database drivers now.
