Guide to Creating Roles in MySQL

Create a Role

Write a MySQL query to create a new role named "db_reader".

Solution:

-- This command creates a new role named 'db_reader' in the database system
-- Roles can be used to manage permissions for multiple users efficiently
CREATE ROLE 'db_reader'; 

Explanation:

• Purpose of the Query:
• The goal is to define a new role that can group specific privileges.
• This demonstrates the CREATE ROLE statement for easier privilege management.
• Key Components:
• CREATE ROLE 'db_reader' : Creates a role with the name "db_reader".
• Real-World Application:
• Roles simplify privilege assignment by allowing multiple users to inherit the same set of permissions.
