So no matter what your level of expertise is in SQL, you would find several different SQL questions to solve depending on your skill level.
In this video, I will solve 2 different SQL questions,
First we shall solve the “Users By Avg Session time” question. Now I will be providing 2 different solutions to this problem. One solution using subqueries and the second solution using JOINS. Hopefully this gives you an idea of how to solve a problem using different approaches.
Secondly, we shall solve the “Seat Availability” question. We shall solve this problem using self JOIN and UNION operator.
I will explain in detail my thinking behind solving these problems and also the reasoning behind using certain logic.
