This part-time, flexible program lets you learn SQL for data analysis, backend development, and business intelligence - perfect for working professionals.
Is the W3Schools SQL course worth paying for, or are there better options out there for learning SQL effectively?
W3schools has a pay option?? It used to be my goto for free training. You don’t need that SQL hosting to learn anything. Just go through the free tutorial. It doesn’t have advanced concepts. If you have a computer at home, you can always install MariaDB or MySQL to practice. More on reddit.com

May 9, 2025Is the W3Schools SQL course worth paying for, or are there better options out there for learning SQL effectively?
Currently doing the free course for W3schools, as was recommended to me on this sub reddit. It does a great job at walking you through and giving you tests & examples. I combine it with https://www.sql-practice.com/ and a sql textbook. The website gives you questions and a real database to try and query. More on reddit.com

May 9, 2025Is W3 schools SQL enough to get a job?
It's hard to tell, especially without knowing anything about the organisation at all but some kind of benchmark would be to see how well you can answer your way through DP-203 (or maybe DP-900, in your case?) questions. I suppose you could more or less ignore the Azure specific questions if you aren't going to use it but there are a bunch of good SQL questions sprinkled in there as well; https://www.examtopics.com/exams/microsoft/dp-203/view/ Edit: If you manage to get through DP-203 it'll definitely be enough for a lot of database related work tasks.

August 11, 2022Is W3 Schools a good resource for learning Python, or is there a better free resource available?
Far, far better resource: MOOC Python Programming 2022 from the University of Helsinki. A textual course that sets the main focus on checked practical exercises. W3Schools at utmost is reasonable for web dev, but not for other programming. More on reddit.com

r/dataanalysis on Reddit: Is the W3Schools SQL course worth paying for, or are there better options out there for learning SQL effectively?
May 9, 2025 -
I'm trying to build a strong foundation in SQL for data analytics and career purposes. I came across the W3Schools SQL course, which seems beginner-friendly and affordable. But before I invest in it, I want to know:
Is it detailed enough for practical, job-oriented skills?
Does it cover real-world projects or just basic syntax?
Are there better alternatives (like free or paid courses on Udemy, Coursera, etc.)?
I'd appreciate honest feedback from anyone who's taken it or has experience learning SQL through other platforms. I want something that can take me from beginner to confident user, ideally with some hands-on practice.
Thanks in advance!
