Why ORDER BY Alone Can't Solve LeetCode 2159: SQL Sorting Explained! #viralvideo @tseries #coding

In this video, we dive into the intricacies of SQL's ORDER BY clause and why it can't independently sort two columns as required in LeetCode problem #2159. We'll explore how ORDER BY works, its limitations, and why it falls short for this specific problem.

You'll learn:

The basics of the ORDER BY clause and its default behavior.
How ORDER BY sorts multiple columns and the implications of this sorting method.
Why ORDER BY Alone Can't Solve the Problem: When you use ORDER BY with multiple columns, SQL sorts the entire result set based on the first column and then sorts within those results based on the second column. This means you can't independently sort two columns in different orders (one ascending and one descending) using a single ORDER BY clause. Instead, SQL will prioritize the first column's order and only sort the second column within groups of identical values from the first column.
An alternative approach using Common Table Expressions (CTEs) to independently sort columns and achieve the desired result.
