------解决方案--------------------
这是神马问题，居然还乱码。。。
------解决方案--------------------
mysql字符集编码不正确？
------解决方案--------------------
检查sql语句的语法
------解决方案--------------------
sql语句中有中文吧！更改字符集！
打开%MySQL_HOME%/my.ini

CSS code

[client]

port=3306

[mysql]

default-character-set=[color=#FF0000]utf8[/color]


# 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="C:/Program Files/MySQL/MySQL Server 5.1/"

#Path to the database root
datadir="C:/ProgramData/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=[color=#FF0000]utf8[/color]

# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB

# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

# The maximum amount of concurrent sessions the MySQL server will
# allow. One of these connections will be reserved for a user with
# SUPER privileges to allow the administrator to login even if the
# connection limit has been reached.
max_connections=100

------解决方案--------------------

修改两个地方的default-character-set为utf8

------解决方案--------------------
然后修改已有的表为utf8(GBK也可以)
