Hello all,

I have a simple and off-topic question. This platform has been very useful for me to overcome the challenges in my Julia projects. That is why I wanted to ask this question here. If you think that my question does not fit here, you can remove.

My questions is: Could you please recommend me online courses/resources to learn SQL? I am very familiar with Python, Julia, R, Matlab, C#, and other tools, but I have no idea about SQL. What would you recommend me? I would prefer a free course/resource, but if you think that resources which require payment are much better organized and more helpful, I am willing to pay as well.

I look forward to seeing your suggestions.

Kind regards

[SQLBolt](https://sqlbolt.com/) is very nice for getting started with SQL concepts and for trying them out interactively in the browser itself.

You might consider this:  
[https://datacarpentry.org/sql-ecology-lesson/](https://datacarpentry.org/sql-ecology-lesson/)

It’s “for ecologists” only in the sense that the examples use an ecology dataset, but really it’s for anyone, with no assumed background in databases.
