Hello, At the 1:55 to 2:05 mark of the video the following query shows on the screen: ALTER TABLE sales ---> ADD...; Is this a mistake, if not, what is the relevance to it for running the alternative CASE query? Thanks, Matt

Hi Matt! Thanks for reaching out. Thank you for pointing this out. We have to correct and upload this video and will do as soon as possible. Currently, there's no relation between ALTER TABLE query and what has been shown at the back. Best,Martin
