有以下两张表：
mysql> show tables;
+---------------+
| Tables_in_old |
+---------------+
| book |
| press |
+---------------+
2 rows in set (0.00 sec)
mysql> desc book;
+----------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+-------------+------+-----+---------+-------+
| id | int(11) | NO | PRI | NULL | |
| name | varchar(10) | YES | UNI | NULL | |
| press_id | int(11) | YES | | NULL | |
+----------+-------------+------+-----+---------+-------+
3 rows in set (0.00 sec)
mysql> desc press;
+-------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+-------+
| id | int(11) | NO | PRI | NULL | |
| name | varchar(10) | YES | UNI | NULL | |
+-------+-------------+------+-----+---------+-------+
2 rows in set (0.00 sec)
在往表里插数据时报错了：
mysql> insert into press(name) values
-> ('北京工业地雷出版社'),
-> ('人民音乐不好听出版社'),
-> ('知识产权没有用出版社')
-> ;
ERROR 1366 (HY000): Incorrect string value: '\xE5\x8C\x97\xE4\xBA\xAC...' for column 'name' at row 1
不支持中文，查看下字符编码：
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 | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
发现database的字符编码是latin1，修改字符编码：
mysql> SET CHARACTER_SET_DATABASE=utf8;
Query OK, 0 rows affected, 1 warning (0.00 sec)
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/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
现在看起来修改过来了，现在插入数据：
mysql> insert into press(name) values
-> ('北京工业地雷出版社'),
-> ('人民音乐不好听出版社'),
-> ('知识产权没有用出版社')
-> ;
ERROR 1366 (HY000): Incorrect string value: '\xE5\x8C\x97\xE4\xBA\xAC...' for column 'name' at row 1
发现还是报错，最直接的办法是删库跑路！！！！
不过需要查看当前库的字符编码，然后修改。
