In this video, we will dive deep into subqueries in MySQL and understand how they work. Subqueries are an essential part of SQL that allow us to perform complex queries by nesting one query inside another.

We will explore the following types of subqueries:

Single-Row Subquery:

A single-row subquery returns only one row and one column. It is typically used with operators like =,greater than,less than etc., to compare a single value.

Multi-Row Subquery:

A multi-row subquery returns multiple rows. It's often used with operators like IN, ANY, ALL, and is helpful when you want to compare multiple values.

Correlated Subquery:

A correlated subquery depends on the outer query for its value. The subquery is executed for each row returned by the outer query, making it a bit more complex.

By the end of this video, you will have a clear understanding of these different types of subqueries and how to use them effectively in your SQL queries. Whether you're a beginner or an experienced MySQL user, this video will provide helpful tips and examples to level up your SQL skills!
