Welcome to SQL Part 3! This tutorial focuses on the procedural control and Data Manipulation Language (DML) that power robust database applications.
We dive deep into Stored Procedures—compiled SQL statements used to encapsulate reusable business logic, enhance security, and improve performance. You will learn how to create and execute procedures, including passing input parameters to perform specific tasks like getting total sales by customer or updating segments.
We also cover the fundamentals DML commands: INSERT, UPDATE, and DELETE. This knowledge is essential for every backend developer and database administrator!
