Day 13 SQL Masterclass : Master User-Defined Functions, Transactions, and Stored Procedures

"Welcome to Day 13 of our SQL Masterclass! In today's session, we dive deep into User-Defined Functions (UDFs), Transactions, and Stored Procedures in SQL Server. Learn how to extend SQL functionality with custom functions, ensure atomic operations with transactions, and automate complex processes with stored procedures. From swapping employee salaries to transferring account balances, we cover it all with practical examples."

Explanation of Queries
User-Defined Functions: Functions extend SQL by enabling custom calculations and reusable logic. The total_customer_payments function, for example, takes customer names as input and calculates the total payment made by that customer.

Transactions: A transaction ensures that either all operations succeed or none do, maintaining data consistency. For example, swapping employee positions and salaries happens in a transaction to avoid data inconsistency in case of an error.

Stored Procedures: Procedures automate repetitive tasks in SQL, like transferring balances between accounts or swapping employee details. They are more powerful than functions, as they can modify the database state.
