#mysql错误

本文详细介绍了在使用Java连接MySQL数据库时遇到的字符集错误，包括未知的初始字符集索引'255'和未知的字段字符集索引'255'，并提供了通过调整连接参数和升级MySQL JDBC驱动版本来解决这些问题的方法。

开始出现错误（1）

java.sql.SQLException: Unknown initial character set index '255' received from server. Initial client character set can be forced via the 'characterEncoding' property.错误提示

根据提示在连接数据库时增加编码

useUnicode=true&characterEncoding=utf8

后出现错误（2）

Unknown character set index for field '255' received from server

错误（2）是我的mysql的jar版本太低了，由5.0.3换成5.1.47就没有错误了。

当你使用框架，用main方式执行sql语句，结果报错： java.sql.SQLException: Unknown initial character set index '255' received from server. Initial client character set can be forced via the 'characterEncoding' property. 那可能原因是数据库编码的问题， 可以在eeys（数据库名）后边加入： ?useUnicode=true&
