Assign Database Privileges for MySQL User

Grant Privileges to a User

Write a MySQL query to grant SELECT and INSERT privileges on the SalesDB database to the user "gaioz_amira".

Solution:

-- This command grants specific privileges to the user 'gaioz_amira' connecting from localhost
-- Grants permission to SELECT (read) and INSERT (add) data in all tables of SalesDB
GRANT SELECT, INSERT ON SalesDB.* TO 'gaioz_amira'@'localhost';

Explanation:

• Purpose of the Query:
• The goal is to provide the user "gaioz_amira" with the ability to read and add data in the SalesDB database.
• This demonstrates the GRANT statement for assigning specific privileges.
• Key Components:
• GRANT SELECT, INSERT : Specifies the privileges to be granted.
• ON SalesDB.* : Applies the privileges to all tables within the SalesDB database.
• TO 'gaioz_amira'@'localhost' : Identifies the user who receives these privileges.
• Real-World Application:
• Used in systems where users need limited access to perform specific operations on a database.

Notes:

• Always grant only the necessary privileges following the principle of least privilege.
