SQL Learning Resources Thread
As a Beginner learning Data Analysis, Data Science + SQL, it is always good to connect the dots through projects and use cases.
In this growing thread, I will first share some resources with possible SQL projects to test your skill

It will be good to start with a foundational course. there are lots of resources in this space so I will list them:

Foundation
1. Udacity Free SQL Course: udacity.com/course/sql-for…

2. W3Schools. Don't joke with this site. highly valuable and resourceful. You also have the opportunity of trying out the queries without installing any software on your laptop.
w3schools.com/sql/

3. SQLCourse: This is another amazing site with easy-to-read instructions just like W3Schools and an online SQL interpreter.

4. SQLBolt
Still on the fundamentals. there are lots of resources out there and SQLBolt is one of them

sqlbolt.com

All Levels
1. Hackerrank:
I love the hackerrank approach to learning SQL. You learn by solving challenges and acrrued points to move across levels.

A 30 minutes on hackerrank everyday for 60 days will make a significant impact

before I move on from Hackerrank, companies today access your SQL skill by sending you tasks on hackerrank. so, the faster you've gone learning and practicing there, the better you are to write efficient queries

2. Leetcode: This is yet another superb SQL learning resource. select different tasks to solve.

very similar to hackerrank, some organizations also test your SQL skill with Leetcode assessment

3. Select Star SQL:

This is an interactive book that aims to be the best place on the internet for learning SQL. It is free of charge, free of ads, and doesn't require registration or downloads.

I will also recommend Danny Ma's 8 Weeks SQL Challenge as a good resource:
