It was used to just show how "alter table" command works ! 😛
He just meant that as an example. However, you can use that column to keep some user hidden to all your users.
For example if you are going to use this table to create a list of all user for management, standard user will have access to user with variable visible=1 and administrators will have access to users with variable visible 1 and 0.

Hi
May I know what is the purpose of that visible column please.. why it is used for is there any specific reason for that column.
Since you can't be bothered to level your mic volume properly I'm skipping this since it's barely audible.
thanks for the videos it was EXTREMELY helpful!
i like the approach you take by taking things slowly, explaining evertyhing in detail and going through the process step by step. This way, beginners like myself are really able to understand how to do basic commands. great job!
i think you could do even better by explaining the installation process. personally, i was lost trying to figure out which SQL installer i needed. i got that sorted out though! 🙂
is this shit stops at chapter 5?
cuz the guys was good and all i need more plz PM if there's a thread so i can find more of this beginners stuff
so simple, thank you very much…

Hi there, thanks for uploading such informative videos. They are really useful for beginners. What i didn't get there is if we delete any rows then the id does not auto increment itself. i.e when you delete the first row then everything in the first row get deleted. That's OK but why doesn't that second row id(2) get changed to 1 after deletion the first row. How can i make it working? Hope, you will reply. Bye
