我们曾在前一些文章对MySQL乱码的实际解决方案有一些相关的介绍，我们今天主要向大家描述的是MySQL乱码处理的经验总结，以及实际的解决办法，以下就是对其具体内容的分析，望你会有所收获。
MySQL乱码处理总结:
(1)java中处理中文字符正常,在cmd client中显示乱码是字符集的问题.
(2)字段长度设置够长,但插入中文字符时提示com.MySQL.jdbc.MySQLDataTruncation: Data truncation: Data too long for column错误是字符集的问题.
(3)乱码问题归根到底是字符集的问题,那就从字符集设置方面考虑,不外乎下面几个方面:server,client,database,connection,results.
解决办法
(1)修改 my.ini(MySQL Server Instance Configuration 文件)
<ol class="dp-xml"> <li class="alt"><span><span># CLIENT SECTION </span></span></li> <li><span>[client] </span></li> <li class="alt"> <span class="attribute">port</span><span>=</span><span class="attribute-value">3306</span><span> </span> </li> <li><span>[MySQL] </span></li> <li class="alt"> <span class="attribute">default-character-set</span><span>=</span><span class="attribute-value">gbk</span><span> </span> </li> <li><span># SERVER SECTION </span></li> <li class="alt"><span>[MySQLd] </span></li> <li> <span class="attribute">default-character-set</span><span>=</span><span class="attribute-value">gbk</span><span> </span> </li> </ol>
(2)修改data目录中相应数据库目录下的db.opt配置文件
<ol class="dp-xml"> <li class="alt"><span><span class="attribute">default-character-set</span><span>=</span><span class="attribute-value">gbk</span><span> </span></span></li> <li> <span class="attribute">default-collation</span><span>=</span><span class="attribute-value">gbk_chinese_ci</span><span> </span> </li> </ol>
(3)数据库连接串中指定字符集
URL=jdbc:MySQL://yourIP/college?user=root&password=yourPassword&useUnicode=true&characterEncoding=gbk
注:在MySQL4.1.0版 要加useUnicode=true&characterEncoding=gbk 如果是5.0版以上的，加不加都是没有关系的！
(4)在创建数据库时指定字符集
<ol class="dp-xml"><li class="alt"><span><span>create database yourDB CHARACTER SET gbk; </span></span></li></ol>
(5)在dos命令上要设置
<ol class="dp-xml"><li class="alt"><span><span>set names gbk </span></span></li></ol>
好了,经过检查上面四个方面的设置,应该 OK 了!不会出现诸如
com.MySQL.jdbc.MySQLDataTruncation: Data truncation: Data too long for column等问题.

How to solve mysql cannot be started
Apr 08, 2025 pm 02:21 PM
There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.
Does mysql optimize lock tables
Apr 08, 2025 pm 01:51 PM
MySQL uses shared locks and exclusive locks to manage concurrency, providing three lock types: table locks, row locks and page locks. Row locks can improve concurrency, and use the FOR UPDATE statement to add exclusive locks to rows. Pessimistic locks assume conflicts, and optimistic locks judge the data through the version number. Common lock table problems manifest as slow querying, use the SHOW PROCESSLIST command to view the queries held by the lock. Optimization measures include selecting appropriate indexes, reducing transaction scope, batch operations, and optimizing SQL statements.
How to use SUBSTRING_INDEX in MySQL
Apr 08, 2025 pm 02:09 PM
In MySQL database operations, string processing is an inevitable link. The SUBSTRING_INDEX function is designed for this, which can efficiently extract substrings based on separators. SUBSTRING_INDEX function application example The following example shows the flexibility and practicality of the SUBSTRING_INDEX function: Extract specific parts from the URL For example, extract domain name: SELECTSUBSTRING_INDEX('www.mysql.com','.',2); Extract file extension to easily get file extension: SELECTSUBSTRING_INDEX('file.pdf','.',-1); Processing does not exist
Does mysql need the internet
Apr 08, 2025 pm 02:18 PM
MySQL can run without network connections for basic data storage and management. However, network connection is required for interaction with other systems, remote access, or using advanced features such as replication and clustering. Additionally, security measures (such as firewalls), performance optimization (choose the right network connection), and data backup are critical to connecting to the Internet.
Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
The primary key of mysql can be null
Apr 08, 2025 pm 03:03 PM
The MySQL primary key cannot be empty because the primary key is a key attribute that uniquely identifies each row in the database. If the primary key can be empty, the record cannot be uniquely identifies, which will lead to data confusion. When using self-incremental integer columns or UUIDs as primary keys, you should consider factors such as efficiency and space occupancy and choose an appropriate solution.
Does mysql need a server
Apr 08, 2025 pm 02:12 PM
For production environments, a server is usually required to run MySQL, for reasons including performance, reliability, security, and scalability. Servers usually have more powerful hardware, redundant configurations and stricter security measures. For small, low-load applications, MySQL can be run on local machines, but resource consumption, security risks and maintenance costs need to be carefully considered. For greater reliability and security, MySQL should be deployed on cloud or other servers. Choosing the appropriate server configuration requires evaluation based on application load and data volume.
Can mysql return json
Apr 08, 2025 pm 03:09 PM
MySQL can return JSON data. The JSON_EXTRACT function extracts field values. For complex queries, you can consider using the WHERE clause to filter JSON data, but pay attention to its performance impact. MySQL's support for JSON is constantly increasing, and it is recommended to pay attention to the latest version and features.
