Описание к видео Find and Remove Duplicate Rows in SQL using Windows Functions | EssentialSQL

If you're interested in learning SQL, then why not hop on over and get our Windows Functions course today at: https://www.udemy.com/course/sql-wind...

SQL window functions allow you to find and remove duplicates in your data with ease. Using functions like ROW_NUMBER you can partition your data by a specific column or set of columns and assign a unique rank or row number to each row within that partition. You can then use this information to identify and remove duplicates from your dataset. This technique is particularly useful when dealing with large datasets and can help to ensure the accuracy and consistency of your data.
