In this video, I walk you through a common SQL interview question: how to find duplicate records in a table. I demonstrate this using a sample employees table with 7 records, focusing on the employee name, department, and salary. I also explain how to use a SQL query with the COUNT function to identify duplicates effectively. Please make sure to follow along and try running the query yourself.
