Özet
 Learn SQL in a single focused day — no computer science degree required.SQL is the language behind almost every app, website, and business report on earth. If you’ve ever wanted to pull your own numbers, answer your own questions, or finally understand what a “join” is, this book gets you there fast.What’s SQL? Learn It in 8 Hours is a hands-on, beginner-friendly crash course from computer science professor John Rouda. Instead of dry theory, you learn by doing: every example runs against one small sample database — the Daily Grind, a neighborhood coffee shop — so each new idea builds on the last.Inside, you will learn how to:Write your very first SELECT statement in minutesFilter, sort, and summarize data with WHERE, ORDER BY, and aggregate functionsCombine tables with every kind of JOIN — and know which one to reach forUse subqueries, set operations, views, and CTEs to write elegant queriesDesign your own tables, keys, and constraints the right wayProtect your data with transactions and understand the basics of securitySpeed up slow queries with indexes and read a query planMove confidently between MySQL, PostgreSQL, SQLite, and SQL ServerYou’ll also get checkpoints to test yourself, a full statement and function reference, a glossary, hands-on exercises with solutions, and a complete capstone project.Perfect for students, career changers, analysts, developers, and anyone who needs to get answers out of a database — fast. Open it this morning; write real queries by tonight.©2026 John Rouda (P)2026 John Rouda
