Use the MySQL console for database operations

MySQL is a popular relational database management system that provides a console interface for database operations. In this article, we will introduce how to use the MySQL console to perform common database operations, including creating databases, creating tables, inserting data, querying data, and updating data, etc. Below are detailed steps and corresponding source code examples.

1. Connect to MySQL server

Before starting, you first need to connect to the MySQL server. Open a terminal or command prompt and enter the following command:

mysql -u 用户名 -p 密码

Replace "username" with your MySQL username and "password" with your MySQL password. After pressing Enter, if the username and password are correct, you will successfully connect to the MySQL server and enter the MySQL console.

2. Create database

To create a new database, use the following command:

CREATE DATABASE 数据库名;

Replace "database name" with the name of the database you want to create. For example, to create a database named "mydatabase", you can run the following command:

CREATE DATABASE mydatabase;

3. Select database

Before doing any database operations, you need to select the database you want to use. Use the following command to select the database:

USE 数据库名;

Replace "database name" with the name of the database you want to use. For example, to select the "mydatabase" database you created earlier, you can run the following command:

USE mydatabase;
