Embark on a journey of SQL problem-solving in our latest tutorial! In this session, we unravel the mystery of missing numbers within a sequence using Recursive Common Table Expressions (CTE). Join us for a detailed walkthrough, where we demonstrate the power of SQL queries to identify and fill the gaps in a user-defined sequence.

📋 Problem Description:
The challenge involves generating a list of numbers using recursive CTE and identifying the missing numbers from a given user sequence. The "user_nums" table contains a subset of numbers, and our goal is to find the absent values.
