原来常常在群里看到MySQL的乱码问题,但是由于本人一直在用oracle和sql server所以没多在乎,昨天用了用MySQL结果就遇到了传说中的乱码…..。现在我们来讲讲MySQL的乱码问题。首先你进入的你MySQL
用show variables查看
这里可以查看到你的字符集,character_set_server是服务器编码。现在我们默认的是latin1要改变服务器的编码必须重新启动服务器,我们先用MySQLadmin –uroot shutdown关闭服务器,然后MySQLd –C GBK启动服务器 –C是character_set_server的一个简写(可以也可以写成MySQLd –character_set_server gbk).这样修改以后我们再进入MySQL查看就会显示:
这样我们就把服务器和数据库的编码改为了GBK。
现在我们就可以插入中文字符串了,但是为什么有时间还是会显示
<ol class="dp-xml"><li class="alt"> <span>Exception in thread "main" com.MySQL.jdbc.</span>MySQL<span>DataTruncation: <p></p>Data truncation: Data too long for column 'name' at row 1 </span> </li></ol>
MySQL中文乱码解决中出现上述情况,这是因为你只是修改了MySQL的服务器的字符编码,并没有修改已经有数据库的编码,这时候你需要手动的把data目录下的数据库中的db.opt中的编码改为
<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>
这样修改以后你在重启服务器就可以插入中文了。
但是这时候还有个问题就是在你应用程序当中显示的是中文字符,但是在命令窗口还是乱码。
这时候你注意我们上面图中的character_set_client字符还是latin1当然显示的是乱码咯哟。所以你进入MySQL客户端程序的时候因该把客户端默认的编码改为gbk才能显示正常。
你可以在MySQL里修改,也可以在登陆的时候MySQL –uroot –default-character-set=gbk修改
如此以来就解决了MySQL中文乱码解决了。

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

The key to installing MySQL elegantly is to add the official MySQL repository. The specific steps are as follows: Download the MySQL official GPG key to prevent phishing attacks. Add MySQL repository file: rpm -Uvh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm Update yum repository cache: yum update installation MySQL: yum install mysql-server startup MySQL service: systemctl start mysqld set up booting
