@@keremardicli4013 Speed, in MSSQL for example procedures and triggers tend to be a lot faster then using a shit language like php. since everything is done within sql. All those shitty queries you tend to make with an ORM and some linked list garbage speed up tons. For example recently I had to generate questions for something based on the database that was being used. Alas I did it in MSSQL with procedures and triggers to build the whole procedure.

Cool. I have a question if you don't mind i just started SQL out of curiosity. I understood how to make a database. My question is how do i make it user friendly i mean what if some one has to enter a data into my database but they shouldn't use insert statement. Something like a data entry form ? How do i make connections to database and data entry form ? Sorry if this is a stupid question

2 things for anyone still trying to use this guide in 2022 for Windows. The installer does not set the PATH variable for MySQL! You have to add the bin folder to your path variables manually. Also be sure to select the legacy authentication system when installing or else the VSCode extension he recommends won't work and give you a "Client does not support authentication protocol requested by server" error.

​​@@toopkarcher he means that varchar can have a number of characters upto the length you specify, which means that if you tell it to have 255 it will go upto that number while also can be less for eg 200, 15 or even 0 which is Null. But char will always have fixed number not more not less and since no country code comprises less than two letters/chars you can tell dbms to have exactly two characters for country code. But as far as i think it won't save space and it it does it would be varchar instead.

Fun trivia: the "My" in MySql stands for the Swedish author's daughter who was named My, which is pronounced like regular "M", plus the initial "Y" note from "You". It's not a pronunciation you have to change. Keep calling it MySql, as in "SQL that is mine", no need to confuse your coworkers about the native pronunciation of the app. It's like you have imported the name into your language, but haven't changed the spelling :P like how most languages do for other country names, ex Sweden vs Sverige, Germany vs Deutschland, MySQL vs MySQL :)

And SQL is actually really easy to learn (as you have shown), so no need for an ORM! They'll only slow you down by being a weird black box you'll have to mess with after some point.

16:40 The code here is incorrect and will NOT work the way you intend it to, because: the "Rooms.owner_id = guest_id" part will find rooms where the owner is also the guest (i.e. owner books his/her own room), instead, it should be replaced with "Rooms.id = room_id" which matches room ID in Rooms table and Bookings table. Otherwise, excellent informative video!

Since you typically only create a DB or table once it's usually easier to use a visual tool, like drawsql, to design the database and export the code. Writing the create commands by hand for something you're only going to run once is a PITA.

This video is a great supplement. I am currently reading Designing Data Intensive Applications and a lot of what is shown here is mentioned in the early chapters of the book but in a more practical way.

I would like to briefly note that in almost every video you get equally good suggestions, as far as extensions for VSC are concerned. Thanks for that!

If you're using MySQL, I'd recommend using MySQL Workbench for modelling and server management. As you can do anything from synchronizing a deployed MySQL server to your model, to transferring schemas across servers seamlessly.

Thank you for this video I watched a few others before this one popped up and this is the only one that didn't assume prior knowledge despite being titled as for beginners. While I won't master the subject in a 17 minute video I finally know a place to start.
