What will I learn?

Beginner SQL Course gives you practical skills to query real subscription and payment data fast. You will learn SELECT, WHERE, ORDER BY, joins, and set operations, then move into GROUP BY, aggregates, and HAVING for powerful reporting. You also handle dates, NULLs, and open-ended subscriptions, plus defensive query design and testing so your SQL is accurate, efficient, and ready for everyday analytics.
