mysql应用学习-解决数据乱码

原因

mysql数据库character_set_database和character_set_server默认编码是latin1,所以导致乱码；

修改步骤

step1. 修改my.ini配置

　　在[mysqld]组下添加character_set_server=utf8;我的配置:

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

# *** default location during install, and will be replaced if you

# *** upgrade to a newer version of MySQL.



[mysqld]



# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M



# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin



# These are commonly set, remove the # and set as required.

# basedir = .....

# datadir = .....

# port = .....

# server_id = .....



basedir=D:/mysql-5.6.20-winx64

datadir=D:/mysql-5.6.20-winx64/data

character-set-server=utf8

#character-set-connection=utf8

#character-set-results=utf8



# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M 



sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

step2. 重新启动mysql服务

　　输入命令：net stop mysql

　　停止服务后，

　　输入命令：net start mysql

step3. 查看修改结果

　　重启mysql服务后，进入mysql,

　　输入命令：show variables like 'character%';

　　显示结果：

　　

　　这时以文本形式插入数据，显示正常：

　　

其他

　　在这提一下default_character_set，它在mysql5.5.3中已移除，详情请看--default-character-set=charset_name。
