mysql -uroot -h localhost -proot1234 --default-character-set=latin1 show variables LIKE '%chara%'; 注:1 该方式在服务端不指定该方式在服务端不指定character-set-server时有效。 2 同理可以在客户端配置里指定default-character-set参数。 注: 1 参数default-character-set=utf8mb4是客户端里的参数。
‘utf8mb4’ 是一个兼容性更好的字符集,与 .Net Framework 更好地兼容。我们需要在应用程序的连接字符串中修改字符集。 假设我们的连接字符串如下所示: stringconnectionString="Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;CharSet=utf8mb3;"; 1. 我们需要将 ‘utf8mb3’ 修改...
2. 服务器接收到客户端发送来的请求其实是一串二进制的字节,它会认为这串字节采用的字符集是character_set_client,然后把这串字节转换为character_set_connection字符集编码的字符。 由于我的计算机上character_set_client的值是utf8,首先会按照utf8字符集对字节串0xE68891进行解码,得到的字符串就是'我',然后按照cha...
当你在数据库操作中遇到“character set 'utf8mb3' is not supported”的错误时,这通常意味着你正在使用的数据库系统不再支持utf8mb3字符集。utf8mb3是MySQL数据库系统早期版本中使用的一种字符集,它只支持最多三个字节的UTF-8编码,因此不能完全支持所有Unicode字符。随着数据库系统的更新,推荐使用utf8mb4字符集...

Character set utf8mb3 is not supported by Net Framework Even thought everything is already set to utf8mb4. Any idea how to fix it? Sorry, you can't reply to this topic. It has been closed.
There are three options in this group: character_set_client, character_set_connection, and character_set_results. The first two options are used by MySQL for writing to tables: The server takes the character_set_client system variable to be the character set in which statements are sent by...
