完美解决MySQL数据库中文乱码问题

在使用MYSQL时,插入中文字符,经常会出现乱码,中文全被用?代替。出现这种情况的原因,多是字符集不匹配造成的。
在MYSQL中,如果使用缺省的字符集,在建库、建表时,默认使用的是latin1字符集,为ISO 8859-1西欧字符集。插入中文字符时,与之不匹配,就会出现乱码。
要解决此问题,就必须手动将数据库Server和Client的字符编码改为gb2312。配置方法如下:
打开MYSQL安装目录下的my.ini文件,找到如下段落:
# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]
port=3306
[mysql]
default-character-set=latin1
# 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:/MySQL/MySQL Server 5.0/"
#Path to the database root
datadir="D:/MySQL/MySQL Server 5.0/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=latin1
将其中的default-character-set=latin1改为default-character-set=gb2312,然后重启MYSQL,运行MySQL Command Line Client:
输入show variables like 'character_set_%';可以查看数据库的字符编码如下:
mysql> show variables like 'character_set_%';
+--------------------------+-----------------------------------------+
| Variable_name | Value |
+--------------------------+-----------------------------------------+
| character_set_client | gb2312 |
| character_set_connection | gb2312 |
| character_set_database | gb2312 |
| character_set_filesystem | binary |
| character_set_results | gb2312 |
| character_set_server | gb2312 |
| character_set_system | utf8 |
| character_sets_dir | D:/MySQL/MySQL Server 5.0/share/charsets|

ok,解决之~~~~
