如何创建一个简单的mysql数据库
这篇文章主要介绍了操作MySQL日志的一些方法,对日志的删除操作做了重点讲解,需要的朋友可以参考下。
一.创建数据库
注:已经安装好mysql。
windows下运行cmd进入命令窗口,本人用的是win7系统,先输入F:进入F盘,然后输入“cd F:\mysql\mysql-5.7.18-winx64\bin”(注:不要引号,路径为自己解压mysql的路径)。
输入net start mysql 启动服务,输入net stop mysql 停止服务,
输入mysql -u root -p后会提示输入密码,输入密码后进入mysql控制台。
二.创建数据库
输入create database student ;创建数据库(student为数据库名)
使用 show databases;查看有哪些数据库
输入use student命令出现这个即可以创建一个数据库表,
输入create table tb_stu1 (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(30) DEFAULT NULL,
`sex` varchar(2) DEFAULT NULL,
`birthday` date DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;
注:tb_stu1位表名
使用show tables查看test下的表名,
建好之后使用describe tb_stu1;查看(注:一定要使用use student进入数据库之后才能使用这个命令)
使用INSERT INTO tb_stu1(id,name,sex,birthday) VALUES ( 1,'小明', '男', '2015-11-02');加入数据,
使用select * from tb_stu1;查看数据
使用TRUNCATE TABLE tb_stu1;清空数据

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.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

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.

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.

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.

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
