Learning SQL does not need a course fee or an install. It needs one hour a day and a plan you actually follow.
This plan gives you 14 days, one topic a day, in ONE AI chat you keep for all 14 days, so it remembers your plan and your mistakes. Days 1 to 5: SELECT, WHERE, ORDER BY, LIMIT and GROUP BY. Days 6 and 7: combine them and practise. Days 8 to 10: JOIN two tables. Days 11 to 14: a mini project on a marks table. Inside: the Day 1 setup prompt, the one-line daily message, a query for each day, practice tables you paste in, and four free places to practise online.
