Descrizione dell’articolo da parte del venditore

Paperback. You know SQL. The problem is remembering it when you actually need it.You remember SELECT. You remember joins. But under interview pressure-or while staring at a query at work-can you immediately explain why WHERE cannot filter SUM(total), why a LEFT JOIN can accidentally behave like an INNER JOIN, or what NULL does to NOT IN?SQL in 10 Minutes is a fast visual refresher for people who have seen SQL before and want the useful parts back in working memory.This is not a from-zero SQL course. It is not a 600-page textbook. And it is not a flimsy cheat sheet.It is a compact, MySQL-leaning field guide built around practical examples, result sets, visual mental models, recall drills, and the mistakes that actually cause confusion in interviews and real work.Inside you'll refresh: - Logical query processing: FROM WHERE GROUP BY HAVING SELECT- NULL and three-valued logic- IN, BETWEEN, LIKE, EXISTS, operators, and precedence- ORDER BY, LIMIT, aggregates, GROUP BY, and HAVING- INNER, LEFT, RIGHT, and full-outer-join concepts- Join multiplication and duplicate-looking rows- INSERT, UPDATE, DELETE, TRUNCATE, and DROP- Transactions, COMMIT, ROLLBACK, and SAVEPOINT- MySQL numeric, text, and temporal data types- TIMESTAMP time-zone behavior vs. DATETIME- Primary keys, foreign keys, constraints, and referential actions- Indexes and EXPLAIN- Views, CTEs, CASE, set operations, and window functions- Important SQL Server-to-MySQL syntax differencesThroughout the book, recurring examples reduce context switching so you can focus on the SQL-not on learning a new toy scenario every page.Use it before a technical screen. Before an interview. Before a meeting. Or keep it beside your keyboard for the moment when you know the concept but cannot remember the exact syntax.Short enough to start now. Useful enough to keep nearby. This item is printed on demand. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability. …
