I was asked a question where I have to show only those product_id, product_name where there a constant growth in sales_amount each year. If there is a decline in sales in any year, it shouldn't be included in the output. Let's say the data is from 2011 to 2021. Need to know the approach for this question.

[@LearnatKnowstar]

You can first calculate the YoY growth for each product in a CTE. Then you can filter on products for which there is a negative growth in any of the years. In the last step, Select all products where product NOT IN ( the products returned in the negative growth scenario)
