1. MySQL garbled code problem
The default character set used by MySQL is Latin1, but in most cases, we need to use the UTF-8 character set , because the UTF-8 character set supports multiple language text encodings and can meet the needs of most applications. In MySQL, we can set the character set through the following steps:
Modify the MySQL configuration file my.cnf and add the following statement under [mysqld]:
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
Modify the MySQL default character set and execute the following command:
SET character_set_client=utf8;
SET character_set_connection=utf8;
SET character_set_database=utf8;
SET character_set_results=utf8;
SET character_set_server=utf8;
The above two methods are to modify the default character set of MySQL to UTF-8, thereby avoiding garbled characters when reading or writing data.
2. JSP garbled code problem
JSP garbled code problem most often occurs when the form submits data. This is because the data sent by the browser to the server is manually input by the user, and the character encoding may be a variety of possible encoding methods, including GB2312, Big5 and other encoding methods, resulting in garbled characters after the data is transmitted to the server.
The methods to solve the problem of JSP garbled characters generally include the following:
Add the following code to the head of the JSP page:
In the form Set the character encoding to UTF-8:

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') ”。

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。

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)..”。

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。
