How to access MySQL shell?

Accessing the MySQL Shell

To access the MySQL shell, you need to have MySQL installed on your system. The MySQL shell, also known as the MySQL client or the MySQL command-line interface (CLI), is a tool that allows you to interact with a MySQL database server.

Step 1: Install MySQL

Depending on your operating system, you can install MySQL in different ways. For example, on a Linux system, you can use your package manager (e.g., apt, yum, or dnf) to install the MySQL server and client packages. On a Windows system, you can download the MySQL installer from the official website and follow the installation wizard.

Step 2: Start the MySQL Shell

Once you have MySQL installed, you can start the MySQL shell by following these steps:

Open a terminal or command prompt on your system.
Type the following command to start the MySQL shell:

mysql -u [username] -p

Replace [username] with your MySQL user account name. The -p option will prompt you to enter your MySQL user password.

Step 3: Interact with the MySQL Shell

Once you're in the MySQL shell, you can execute various SQL commands to interact with your MySQL database. Here are some common commands you can use:

SHOW DATABASES;: Lists all the databases available on the server.
USE [database_name];: Switches to the specified database.
SHOW TABLES;: Lists all the tables in the current database.
SELECT * FROM [table_name];: Retrieves all the data from the specified table.
INSERT INTO [table_name] VALUES (...);: Inserts new data into the specified table.
UPDATE [table_name] SET [column] = [value] WHERE [condition];: Updates existing data in the specified table.
DELETE FROM [table_name] WHERE [condition];: Deletes data from the specified table.
EXIT; or QUIT;: Exits the MySQL shell.

Here's a visual representation of the steps to access the MySQL shell:

By following these steps, you can easily access the MySQL shell and start interacting with your MySQL database. Remember to replace [username] with your actual MySQL user account name, and be sure to have the necessary permissions to perform the desired operations.
