@@techTFQ does the way of window clause not work in SQL SERVER as I am getting error while doing so?? Below is the query I am using @techtfq select distinct product_category, FIRST_VALUE(product_name) over w as most_expensive_product_in_each_category, FIRST_VALUE(price) over w as price_of_most_expensive_product, LAST_VALUE(product_name) over w as least_expensive_product_in_each_category, LAST_VALUE(price) over w as price_of_least_expensive_product from products window w as (partition by product_category order by price desc range between unbounded preceding and unbounded following)

It's not easy to watch an hour of new concept continuously but your videos are exception. It's really interesting though I'm pretty new to these concepts. Thanks a lot for making these videos.

Hello Thaufiq, I’m on my SQL learning journey and came across your channel, thank the KZfaq algo lords. Previously, I used to refer to the documentation pages to learn SQL and would easily get lost in understanding nuances. Your succinct explanation on LAST_VALUE() default frame just saved me loads of time. Huge thanks. Subscribed.
