Very basic and limited

This is a very, VERY basic primer for a very specific version of SQL

Great help! Thank you

I’ve read most of the material before from books, but the way the explanations were laid out and the language used was so clear and matched my way of thinking. It’s the first time I have completely understood all the join types. Feeling like I’ve achieved something so thank you. I will be continuing to use the app as a reference for a long time.

Exactly what I was looking for

Simple, very very simple my only complaint is theres not enough content to really justify the app but I still like it

Отличная шпаргалка

Спасибо

Is what it says, elementary

Elementary SQL, very elementary. If you've written SQL on the job anywhere chances are this will teach you little to nothing. It's very bland though but is focused on simple presentation. If your learning or taking a class, the visuals are nice for things like outer joins. Good start!
