在MySQL數據庫中， 當插入數據無法支持中文時， 可將該數據庫的編碼集設置為utf8， 故在創建數據庫時， 將數據庫編碼集及其他字符編碼設置為utf8。
如果之前創建的數據庫的數據庫編碼集不為utf8， 可以進行如下設置：
mysql> alter database 數據庫名 character set utf8;
或刪除原有舊的數據庫， 再重新創建新的數據庫並將默認的編碼集設置為utf8:
mysql> create database 數據庫名 DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
* 刪除數據庫：
mysql> drop database dbname if exists dbname;
* 創建數據庫：
mysql> create database dbname if not exists dbname；
為確保 create database dbname 命令創建的數據庫編碼集為utf8， 我們可對mysql的配置文件進行修改windows下的mysql配置文件為my.ini， my.ini存在於mysql的安裝目錄下linux下的mysql配置文件為my.cnf， mysql.cnf存在於mysql的安裝目錄下或/etc/下在my.cnf或my.ini下找到[mysqld]， 在其下方添加一行：
character_set_server=utf8
然后保存退出， 並重啟mysql服務即可。
查看字符編碼：
mysql> show variables like '%character%';
或
mysql> show variables like 'character_set_%';
或
mysql> use 數據庫名；
mysql> \s
或
mysql> use 數據庫名
mysql> status;
具體操作如下：
mysql> SHOW VARIABLES LIKE 'character_set_%';
+--------------------------+----------------------------------+
| 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/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)
mysql> set character_set_database = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server = utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW VARIABLES LIKE 'character_set_%';
