MySQL - The Basics // Learn SQL in 23 Easy Steps

Have you ever written pages long SQL queries? If so, what were the use cases? I really wonder :)

[@makotv6898]

@@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.

[@Rawyu]

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

[@passionatebeast24]

@@Rawyu you can use HTML form along with php in your web app and sanitize your data . This way you can get user inserted data but avoid sql injection.

9:12 "country" should be CHAR(2) instead of VARCHAR(2) Because country ID always has 2 characters and CHAR absolutely meant for fixed character length. Thus, long term disk usage + performance efficiency.

[@toopkarcher]

[@naturegirl1999]

@@xNaii1 how do you find how many bites one type takes up compared to another?

[@chrisobi02]

@@naturegirl1999 google is the way. Different types use different numbers of bytes to store them, and with regards to char vs varchar, if it's variable the system likely needs to set aside some extra space on the hardware to account for potential resizing etc

[@deadeye8]

​​@@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.

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.

@Mr. Mehi arch is famous for really difficult to install and use (which is not entirely true) so telling "I use arch" is more of a flexing.

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 :)

I think UPDATE, GROUP BY and COUNT should also have made it into the video as they are very bread-and-buttery for SQL. Another thing: I really much prefer working with something like JooQ than an ORM. You get safety and flexibility at the same time. 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.
