Ask HN: What's the fastest way to learn SQL?

I like the SQL course at https://www.hackerrank.com/ see also books by https://en.wikipedia.org/wiki/Joe_Celko to learn how to write really advanced queries.

https://sqlbolt.com/ is a good place to start.

This question been asked multiple times here, go through my history and you will find detailed answers.

OpenAI is a better SQL query writer than any developer I’ve worked with, and it’s not close.

Kinda scary but maybe true. It reminds me of the place I worked at for a while that had built database-backed web sites for 10 years but I was the first person they hired who understood joins.

Make friends with your DBA (assuming you have one)
