Great video! You explained every concept with such confidence and clarity that it actually sounds easy, and I was able to finally understand how to use and create a partition. Thank you for taking the time to make these great videos and for sharing your knowledge.

thanks for the video tom..!! At 1:35 you said when we use ANSI csum with group by at the end, it errs. Actuall i tried and it does not errs however result are not as expected meaning not in useful order.

Sum(1) Over(Order By Product_Id, Sale_Date Rows Unbounded Preceding) As SumOver
