mysql字段注释乱码其他正常

Posted 2023-05-16

mysql中字段的注释为乱码其他的正常该如何解决？

phpmyadmin 在显示的时候你可以调整显示编码（与数据库安装时默认编码一致时），phpmyadmin查到数据显示的就不是乱码，但phpmyadmin页面显示的是别的鸟文，只有数据是正确显示，所以你导入数据的时候在调整显示编码后再导入，一切都会正常。 参考技术A 应该 用 在server.xml文件里改成 <?xml version='版本号' encoding='utf-8'?> 来解码
就ok了 参考技术B 是因为终端编码和mysql server设置编码不一致造成的 参考技术C SQL脚本文件的问题！修改脚本文件的字符编码即可！ 参考技术D 字符集设置错误了

R连接mysql乱码，看清是查询语句在r软件里是正常的，穿到mysql就乱码了，郁闷！！！

好烦~各位童鞋我的乱码不是查询后字符编码不对，是我用RODBC连接mysql后sqlquery()方法里的中文到了mysql里就变成乱码了，我的obdc和r软件都设置了utf8，mysql也设了utf8，啊啊啊啊好烦~~~下面是控制台输出

> print(paste("select building_area,unit_price from sheet1_copy where project = '","万泉寺东里","'",sep = ""));
[1] "select building_area,unit_price from sheet1_copy where project = '万泉寺东里'"
> sqlQuery(channel = channel,paste("select building_area,unit_price from sheet1_copy where project = '","万泉寺东里","'",sep = ""));

跪求大神指点啊~~~~~~~~~~~~~~~~~~~~~

参考技术A 编码格式不一样，把程序和mysql编码格式统一起来就可以了追问

我已经说了。。。。odbc，mysql，R，都设置了utf8，你看清楚好么。。。

追答

把字符串单独拿出来转码

String s=new String（“内容”,"utf-8"）;试试

追问

已经好了，我把R客户端重启了，应该是设置了但是没有及时生效，真是日了狗了。还是谢谢你的帮助。
