Although I learn SQL language in my BI journey, there are still a lot extra knowleadge for me to learn.
Because there is no shortcut for success, just work harder.
There are so many courses online for us to learn SQL, for example:
How can we choose the best one from so many sources?
This blog I want to recommend the best SQL course, which I studied.
It is on Udemy, which is the biggest online learning platform on the world. It has 4.5 ratings and more than 18000 students enrolled.
What we will learn from it?
- SELECT statements
- WHERE clause
- INNER JOIN, LEFT/RIGHT OUTER JOIN, and FULL OUTER JOIN
- GROUP BY clause
- ORDER BY
What is the difference between it and other sources?
- Video lessons to teach you the contents.
- Practice problems or additional tutorials to help you reinforce.
Of course, it isn’t enough to make you a professional, but it’s enough to get you started in your SQL journey.
