I want to learn SQL for data analysis(I've understood company's database organization)

[oslon]

A beginner product support engineer wants to enhance his SQL data analysis skills.

All I can do is do some subqueries between n tables and WHERE and LIKE clause.

I tried hackerrank and stratascratch but no avail. But the issue that I was facing is that I could only solve unguided problems using chatgpt. I need a set of problems in exactly ascending order of difficulty.

I'm from Nepal and SQL developer roles are in high demand here.

There's a beginners' SQL tutorial in my forum signature. It may help.
