Why this one

The data is sitting in tables. The questions keep coming. What you lack is the language between the two — and the confidence that your query says what you think it says. This book teaches both in one run: 289 pages and 21 chapters from SELECT and WHERE through aggregates, GROUP BY, every kind of JOIN, subqueries and CASE, to indexes with real query plans, transactions, views, window functions and database design with normalization. Every query was run against the book's own practice database before it reached the page, and the real output is printed next to it, so you learn to read results, not just write queries. The 7 projects are an online shop database, a library system with overdue reports, payroll reports, sales analytics with window functions, a student results system, a movie rental analysis and a clinic database capstone.
