In this video, I dive into a commonly asked SQL interview question: how to find all employees who have the same salary. I solve this using a self join approach, which is a powerful technique when you need to compare rows within the same table. I walk through the SQL query step-by-step and explain the logic clearly using simple examples. This method helps avoid duplicates and ensures accurate results. Check out the example, try it on your own, and feel free to drop any questions in the comments.
