MySql 字符编码

MySql的字符编码设置与查看
1、查看字符集设置：
mysql> show variables like ‘collation_%’;
+———————-+—————–+
| Variable_name | Value |
+———————-+—————–+
| collation_connection | utf8_general_ci |
| collation_database | utf8_general_ci |
| collation_server | utf8_general_ci |
+———————-+—————–+
3 rows in set (0.02 sec)
mysql> show variables like ‘character_set_%’;
+————————–+—————————-+
| 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/ |
+————————–+—————————-+
8 rows in set (0.02 sec)
mysql>
2、修改数据库字符集
  
通过MySQL命令行修改:
mysql> set character_set_client=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_connection=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_database=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_results=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_system=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_connection=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_database=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_server=utf8;
Query OK, 0 rows affected (0.01 sec)
通过修改配置文件my.ini：
在安装数据库的地方找到my.ini并设置default-character-set=utf8有两处
