All those shitty queries you tend to make with an ORM and some linked list garbage speed up tons.

[@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

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.

[@chrisobi02]

@@daniellewilson8527 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.

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 :)
