mysql 5.0 中文乱码问题 笔记_MySQL
使用的数据库不多,ms200 ,ms2005 和mysql 5.0 。在ms中都不曾遇到乱码的问题,没想到一转到了 mysql 中就猝不及防的来了。
首先,mysql默认的编码方式是latin 1,这在支持中文上有很大的问题。出现的都是乱码。如果在安装的时候就设置默认编码方式为 utf8 也是不行的,一样的乱码。
在找了一些资料后,总结在这里,以便以后查看使用。厚积薄发。
1、 进入到mysql命令行模式下,输入 password ,进入到命令操作模式。当然前提是开启了 mysql 服务,否则窗口会一闪而过的消失。 这里要先查看default的编码方式【命令】: 【 show variables like "character%"; 】 。语句的后面要跟上冒号,告诉服务器,这是一条语句。 看到的 8 项 variables_name 中value 7 项是 litin 1 。也就是说目前的编码方式是 latin 1.
?2、 进到安装mysql的文件下,找到?my 配置文件,以记事本打开。修改其中的 default-character-set 的值,改为 gbk .一共有两处。
3、 再到命令模式下查看编码方式【show variables like "character%";】 ,看到 variable_name的值都是 gbk 了。
4、新建表,create table user (
id int(11) PRIMARY key AUTO_INCREMENT ,
name varchar(30) not null,sex char(10)
) engine=innodb default charset=utf8;
插入中文数据,再查看的话就可以显示中文了。
5、当然、对于显示中文,设置为 gbk ,utf8,gb2312 都行。【说明】:mysql下utf-8 要写为 utf8 .
6、对于纯命令模式,在很多时候都不太方便。所以就会有很多图形界面的辅助工具。 我比较喜欢的是mysql-front ,在使用这工具的时候,在一开始登录的连接配置里,要把字符集设置为 utf8 ,不然输入的中文数据都会是乱码,也无法读取中文数据。
7、对于 mysql的两种存储引擎模式 ,myisam 和 innodb 。没有什么深入的运用,目前还不能体会出他们的差别。
路漫漫其修远兮,吾将上下而求索。

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
