mysql将表的字符编码转换成utf-8


alter table tb_anniversary convert to character set utf8;

修改数据库mysql字符编码为UTF8

步骤1:查看当前的字符编码方法

mysql> show variables like'character%';

+--------------------------+----------------------------+

|Variable_name           |Value                     |

+--------------------------+----------------------------+

|character_set_client    |latin1                    |

| character_set_connection |latin1                    |

| character_set_database   |latin1                    |

| character_set_filesystem |binary                    |

|character_set_results   |latin1                    |

|character_set_server    |latin1                    |

|character_set_system    |utf8                      |

|character_sets_dir      | /usr/share/mysql/charsets/ |

+--------------------------+----------------------------+

8 rows in set (0.00 sec)

 字符编码为latin1时,用户在给数据表插入一条字符类型(char)的记录,在显示此记录时可能会无法正常显示字符类型的数据,故此处我们将mysql字符编码修改为UTF8。操作如下:

步骤2:修改my.cnf配置文件,修改后如下(/etc/my.cnf):

[client]

#password      = your_password

port           = 3306

socket         = /var/lib/mysql/mysql.sock

default-character-set=utf8     #设置默认编码为UTF8
