MySQL字符集设置

ERROR 1366 (HY000): Incorrect string value错误解决办法

通过命令查看Mysql默认字符集的相关设置：

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)

可以看到，我虽然设置了部分为utf8，但是还有一个默认为拉丁文，可以通过下面方法修改：
方法一：使用配置文件
在Mysql的安装根目录下，my.ini中：

default-character-set = utf8
character_set_server = utf8
Mysql默认字符集，可以在安装时配置，也可以通过Mysql自带的MySQL Server Instance Config Wizard重新配置，配置后重启服务才可生效。

方法二：使用命令修改

mysql> SET character_set_client = utf8 ;
mysql> SET character_set_connection = utf8 ;
mysql> SET character_set_database = utf8 ;
mysql> SET character_set_results = utf8 ;
mysql> SET character_set_server = utf8 ;
mysql> SET collation_connection = utf8 ;
mysql> SET collation_database = utf8 ;
mysql> SET collation_server = utf8 ;
由于版本不同，可能后面命令会执行错误，请忽略即可。修改完成后重启服务即可。

重启服务后再次查看：

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
