Subqueries in MySQL are very useful when data manipulation gets complicated. MySQL is among the most powerful and widely used relational databases. Still, retrieving the exact data you need can quickly become challenging, especially if it involves multiple tables or calculations.

Let's explore the different subquery types, and learn how to use them in your SQL query with many examples and tips. For demonstration, we will use dbForge Studio for MySQL, which provides features for accelerated code editing, building complex queries, and efficient syntax checks.
