🧠 Advanced Features in MySQL: Stored Procedures, Triggers & Views

MySQL offers advanced database functionalities to encapsulate logic and simplify complex operations.

🛠️ Stored Procedures

Precompiled SQL scripts that perform repetitive tasks:

DELIMITER //
CREATE PROCEDURE GetUsers()
BEGIN
  SELECT * FROM users;
END //
DELIMITER ;

✅ Improves performance and maintainability

⚡ Triggers

Automatically execute in response to data modifications:

CREATE TRIGGER before_insert_users
BEFORE INSERT ON users
FOR EACH ROW
SET NEW.created_at = NOW();

✅ Enables data auditing and validation

🪞 Views

Virtual tables created from SELECT queries:

CREATE VIEW active_users AS
SELECT * FROM users WHERE status = 'active';

✅ Provides simplified interfaces and abstraction over underlying data

🎯 Mastery of these features allows developers to design sophisticated, efficient, and secure database applications.
