Solution to Chinese garbled characters when mysql saves data:
The problem lies in the current CMD client window, because the current CMD client input GBK encoding is used, and the encoding format of the database is UTF-8. Inconsistent encoding results in garbled characters.
The encoding format of the current CMD client cannot be modified, so the encoding set of connection, client, and results can only be modified to inform the server that the currently inserted data uses GBK encoding, and although the server's database uses UTF-8 encoding, but it can identify the GBK encoded data notified to the server and automatically convert it to UTF-8 for storage. You can use the following statement to quickly set the encoding set related to the client:
set names gbk;
After the setting is completed, the client can insert data or display data. There is a garbled code problem, but we will soon find that this form of setting will only be effective in the current window. When the CMD client is reopened after the window is closed, the garbled code problem will appear again. So, how to make a once and for all setting?
There is a my.ini configuration file in the MySQL installation directory. By modifying this configuration file, you can solve the garbled problem once and for all. In this configuration file [mysql] is related to the client configuration, and [mysqld] is related to the server configuration. The default configuration is as follows:
[mysql]
default-character-set=utf8
[mysqld]
character-set-server=utf8
At this time, you only need to change the default encodingdefault-character-set=utf8
Change to default-character-set=gbk
and restart the MySQL service.

在mysql中,可以利用char()和REPLACE()函数来替换换行符;REPLACE()函数可以用新字符串替换列中的换行符,而换行符可使用“char(13)”来表示,语法为“replace(字段名,char(13),'新字符串') ”。

方法:1、利用right函数,语法为“update 表名 set 指定字段 = right(指定字段, length(指定字段)-1)...”;2、利用substring函数,语法为“select substring(指定字段,2)..”。

mysql的msi与zip版本的区别:1、zip包含的安装程序是一种主动安装,而msi包含的是被installer所用的安装文件以提交请求的方式安装;2、zip是一种数据压缩和文档存储的文件格式,msi是微软格式的安装包。

转换方法:1、利用cast函数,语法“select * from 表名 order by cast(字段名 as SIGNED)”;2、利用“select * from 表名 order by CONVERT(字段名,SIGNED)”语句。

在mysql中,可以利用REGEXP运算符判断数据是否是数字类型,语法为“String REGEXP '[^0-9.]'”;该运算符是正则表达式的缩写,若数据字符中含有数字时,返回的结果是true,反之返回的结果是false。
