Whether you're just getting started or looking to streamline your database queries, this video walks you through the complete process of working with SQL views from start to finish. I demonstrate how to create your first SQL view, alter existing views, delete views when needed, and most importantly, how to use views as part of larger queries to simplify complex database operations. We start with a practical example using three related tables—product distribution, store information, and product details—and transform a complex join query into a simple, reusable view. You'll learn the key differences between SQL views and stored procedures, with views offering the unique ability to be used within other queries just like regular tables, while stored procedures allow for parameters but can't be nested in SELECT statements. I also cover important limitations, like why ORDER BY clauses can't be used directly inside view definitions and how to work around this. Throughout the video, I show real examples of querying views with WHERE clauses, aggregate functions like SUM, and GROUP BY statements to extract meaningful business insights. By the end, you'll understand exactly when to use SQL views and how they can make your database queries cleaner, more maintainable, and easier for stakeholders to access important data without dealing with complex SQL joins.
