sql delete duplicate records Interview questions using aggregate function

In SQL, to delete duplicate records using the aggregate function MAX, you can identify duplicates based on a unique key and retain the one with the maximum value in another column. Utilizing MAX helps preserve the record with the highest associated value, ensuring data integrity. This method is effective when duplicate records share common characteristics, offering a systematic approach to maintain relevant information and eliminate redundancies. Employing MAX streamlines the deletion process, promoting efficient data management and database optimization.
