mysql - 维基百科转储文件

Question

我将波斯语维基百科 2007 的转储文件导入到我的本地 mysql 5.6。似乎非拉丁脚本中的用户名未正确保存。有什么办法解决吗？

 select DISTINCT rev_user_text from revision where rev_user_text  like '%?%';

+-------------------------------+

可能您没有使用合适的字符集，例如 utf8。尝试使用以下方法重新创建表：

CREATE TABLE revisions
(...)
CHARACTER SET 'utf8';

或更改现有表的字符集：

ALTER TABLE revisions
CHARACTER SET 'utf8';
