Is 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.

May 9, 2025How much is SQL used for data analysis?
Thank you for the quick response. My follow-up question is: in practice then, why aren't these calculations done in the BI tool instead? Is that because the BI tool is somehow not powerful enough or is it because you sometimes need to run some quick one-off analysis so the BI tool doesn't need to be involved?

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!

r/learnSQL on Reddit: Is W3 schools SQL enough to get a job?
August 11, 2022 -
I've just been given a job in data quality assurance but the pay is really bad and I want to move into a better position.
The data manager said that if I learn advanced excel and/or SQL then I would be elligible for better pay and a new role.
If I were to go through https://www.w3schools.com/sql/default.asp and complete all of the content, would that be sufficient to be considered for a job at most companies or is there much more beyond w3schools that would be required to study on a different platform? I know experience matters, but lets ignore that for the sake of the question. Would I know enough to be useful to them?
I would also like to know if there is a minimum amount of the content listed that would be sufficient to become considered useful, or if I need to know everything there because of how things interact with each other.
I don't know anything about SQL so it's difficult for me to know the path forward.
Thanks!

I think that learning the language (SQL) itself is almost useless (and will be an exercise in frustration) if you don't have a solid understanding of the theory of relational databases. Which of course you can learn by yourself, from a book or online, if you are clever and motivated which I assume you are. But it might be better to take a proper course in it. Is this something with which your employer can help? I would also like to know if there is a minimum amount of the content listed that would be sufficient to become considered useful, If I had to evaluate you for a junior position working with databases, I would ask you to normalise a heap of related data into (at least) 3NF, and draw an ERD from the DDL of an existing database. I would also ask you to explain in your own words what a tuple is, and how a JOIN in SQL results in a Cartesian product. Nothing too algebraic, you don't have to be a mathematician, but you'd have to at least be clear about the concepts. So if none of the above makes sense to you, time to study up ;-) And don't be intimidated because it can be a lot of fun actually.
