能够插入的数据：

Database changed
mysql> select * from user;
+----+----------------------+
| id | username |
+----+----------------------+
| 1 | adminadmin |

+----+----------------------+
2 rows in set (0.01 sec)

也就是说对于unicode来讲一个英文字符和一个中文字符是同样大小的，并且varchar(10)中的10就是表示10个unicode码！

由于是处理中文的，因此把D:\Program Files\MySQL\MySQL Server 5.1\my.ini编码设置成以下gbk：

Sql代码 收藏代码 [client]

port=3306

[mysql]

default-character-set=gbk

SERVER SECTION

----------------------------------------------------------------------

The following options will be read by the MySQL Server. Make sure that

you have installed the server correctly (see above) so it reads this

file.

[mysqld]

The TCP/IP Port the MySQL Server will listen on

port=3306

#Path to installation directory. All paths are usually resolved relative to this.
basedir="D:/Program Files/MySQL/MySQL Server 5.1/"

#Path to the database root
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data/"

The default character set that will be used when a new schema or table is

created and no character set is defined

default-character-set=gbk

The default storage engine that will be used when create new tables when

default-storage-engine=INNODB

附注：

更新的数据中有中文，出现以下错误： OperationalError at /admin/blog/post/add/

(1366, "Incorrect string value: '\xE6\xB7\xB1\xE5\x85\xA5...' for column 'title' at row 1")

Request Method: POST Request URL: http://localhost:8000/admin/blog/post/add/ Exception Type: OperationalError Exception Value:

(1366, "Incorrect string value: '\xE6\xB7\xB1\xE5\x85\xA5...' for column 'title' at row 1")

Exception Location: C:\Python25\Lib\site-packages\MySQLdb\connections.py in defaulterrorhandler, line 35

相似这样的错误，应该是数据库表的charset和collation问题。尝试把全部表的charset改成utf-8, collation改成utf8-unicode-ci。若是仍是不能解决，最好是重建数据库，而后修改数据库的属性，选择charset为utf-8,collation为utf8-unicode-ci。命令行：create database cc default charset utf8 collate utf8_unicode_ci; PS：我就是要重建数据库才解决。
