SQL is not dead
Many developers who are excellent at the web can't write a simple JOIN. Yet SQL is one of the few languages that will still be here decades from now.

I’ve met many developers who are very skilled at web development but can’t even write a JOIN between two tables. The moment it’s a LEFT JOIN or a UNION, they’re lost.
Many developers trained at the height of the web era often have a limited grasp of relational databases and SQL. Yet SQL is one of the few languages that, in my view, will still exist decades from now. You might as well learn it and master at least the basics.
A simple, rewarding exercise
My advice: grab a free version of a database system — like PostgreSQL or MySQL —, create a small database with a few tables, and challenge yourself by building increasingly complex queries.
Along the way, you’ll also sharpen your data modeling skills. It’s an investment that will serve you throughout your career. Happy practicing!
