@@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)

This is about easy as it gets to understand, just need to practice so these techniques could stay inside my brain. Good Job, better than most college professor teachings.

[@techTFQ]

Thank you so much 🙏🏼 Glad to know you found this helpful 🙂

I have searched Udemy and many youtube channels to understand the Window functions and finally this video shed the light for an excellent clarity , Once again kudos to Taufiq for an excellent content and clarification :)

[@techTFQ]

Glad it helped!

This is how a tutorial should be. Concise and clear explanation. Greate Job!

I hav spent a lot of money on books a courses but you are the best teacher. I have learned things that were skimmed over elsewhere. Thank you!

[@tejaswi1995]

In the context of "unbounded preceding and unbounded following", this was the only time I understood it. Thanks a lot

[@techTFQ]

Happy to know that :)

[@avikkarmakar2278]

The goto channel to learn SQL. As a non-tech person, I really appreciate the ease of learning and understanding the language

[@sanjoysaha1697]

I have explored so many courses on udemy and on other online platforms but yours is unparallel. Excellent explanation, easy to understand making it stand out from the crowd. You rock man. Thanks for sharing the videos.

[@techTFQ]

Thank you Sanjoy. Appreciate the feedback

[@meghanaiitb]

Hello Thaufiq, I’m on my SQL learning journey and came across your channel, thank the KZbin 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.

[@techTFQ]

Hi Meghana , It means a lot to receive such amazing feedback.. thank you 🙏🏼 I am so glad my content helped you ..

[@artisartisworld8629]

one of the best and easy explanations, even better than what we pay for most of the Udemy courses.

[@ATVhasist-w5w]

[@vaibhavitatekar4700]

I love how you explained the frame clause. It's so easy to understand in your way. Thank you for that

[@deepikameher9343]

Best video ever found on KZbin!! I was scared of SQL queries for all interviews,after going through your videos I have got confidence and creaked interviews as well...Many many thanks to you...the way you explain is superb...Kudos to you !!

[@gojosatoru805]

What questions were asked ?

[@satyaece2007]

Exceptionally articulated starting with every query and data set explanation and I can't believe it's so easy after hearing to your explanation and it's impressive. 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.

For the PERCENT RANK window function example, I believe this would answer the question - How expensive the phone is with regards to the most expensive product rather than how expensive the phone is compared to all the phones(As every phone will have a different price). Liked the content and examples. Thank you.
