This is Sanjeev, the creator of 'The SQL Freedom Course' ! For the past 10 years I've been coding with PHP and SQL. I also coach people on how to write SQL queries.. I started by coaching my clients who ran PHP/WordPress based ecommerce shops and had varied needs to query their data. I started creating The SQL Freedom Course initially to coach my students, who were having difficulty writing sql queries using the traditional 'code-based' method prevalent everywhere. So, as I found my no-code sql training working really well for my students, I decided to release it to the world as I know many will be benefited by learning this no-code way of creating complex sql queries.

F.A.Q
1. Can you connect WooCommerce?

WooCommerce is just MySQL under the hood, so you can just use the MySQL connector inside Flyspeed - I have quite a few students doing this already. This is true for other platforms like Prestashop, Wordpress, etc.

2. I use Google Sheets/ MS Excel for many aspects of my business. Why should I learn SQL?

You’ll get to a point with Excel and Google sheets where eventually the vlookup mess will get out of hand. And it's very hard to continuously keep all your spreadsheets up to date. The amount of copy paste and fiddling involved can get really tedious!

3.What advantage does this no-code sql system offer over a traditional code based system?

For my students whom I was coaching personally, the roadblock in learning SQL was this enormous 'wall of code' which the traditional way of learning SQL pushes in front of you. There is so much to learn, so much to remember...constantly needing to refer to SQL 'cheat sheets' to make sure you have syntax right, tripping over spelling mistakes, trying to remember the SQL 'query processing' order. All doable no doubt, but my student's days are often overloaded with to-dos, And all of this simply used to get in the way of them learning SQL.

4.Shouldn't I be focusing on some AI based Analysis Tool instead of learning SQL?

I think I will let some experts who are heavily invested in AI and ML do the talking for me, as to why you should learn SQL! :)
Read this article - “You don’t need ML/AI. You need SQL.”

That's why analytics tools like Segment, Amplitude and Google Analytics all offer SQL access.
