Welcome to our YouTube video on SQL subqueries!

In this video, we'll be discussing subqueries in SQL and how they can be used to retrieve data from multiple tables or perform more complex queries.

A subquery is a query that is nested within another query, allowing you to use the results of one query to filter or manipulate data in another query. This can be especially useful when working with large databases or when you need to combine data from multiple tables.

We'll cover the basics of subqueries, including how to use them in SELECT, WHERE, and FROM clauses, as well as some common use cases and best practices.

Whether you're new to SQL or just looking to expand your knowledge, this video is for you. We've designed it to be easy to follow and accessible to all levels of SQL users.
