Solution
Working with subqueries is an important skill for data analysts because it allows them to perform complex data manipulations and retrieve specific subsets of data from a larger dataset. Some benefits of using subqueries include improved query performance, increased flexibility in data analysis, and the ability to break down complex problems into smaller, more manageable parts. Additionally, subqueries can be used to combine data from multiple tables, making it easier to extract meaningful insights from relational databases.
