能夠插入的數據：

Sql代碼 收藏代碼 mysql> use varchar_vs_char;
Database changed
mysql> select * from user;
+----+----------------------+
| id | username |
+----+----------------------+
| 1 | adminadmin |
| 2 | 我是中國人我是中國人 |
+----+----------------------+
2 rows in set (0.01 sec)

也就是說對於unicode來講一個英文字符和一箇中文字符是同樣大小的，並且varchar(10)中的10就是表示10個unicode碼！

由於是處理中文的，因此把D:\Program Files\MySQL\MySQL Server 5.1\my.ini編碼設置成以下gbk：

Sql代碼 收藏代碼 [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

附註：

更新的數據中有中文，出現以下錯誤： 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

相似這樣的錯誤，應該是數據庫表的charset和collation問題。嘗試把全部表的charset改成utf-8, collation改成utf8-unicode-ci。若是仍是不能解決，最好是重建數據庫，而後修改數據庫的屬性，選擇charset爲utf-8,collation爲utf8-unicode-ci。命令行：create database cc default charset utf8 collate utf8_unicode_ci; PS：我就是要重建數據庫才解決。
