If you want to know how to write query within another query, then this tutorial is for you.

In this PostgreSQL video tutorial, I have started with an introduction to the concept of subqueries in PostgreSQL. A subquery, also known as the inner query or a nested query is used within another query. Also, I have explained the general format of subqueries. Additionally, I have explained how to use the subqueries with SELECT and FROM clauses.

I have covered the following topics:
What is a subquery in PostgreSQL?
Subquery in the WHERE clause of PostgreSQL
Subquery in the FROM clause of PostgreSQL
Subquery in the SELECT clause of PostgreSQL
