Published by O Reilly in 2021, it focuses on the syntax and behaviors used to query and modify relational databases rather than presenting SQL as a slow, lesson-based course. Its central organizing value is comparative: it addresses important SQL usage in Microsoft SQL Server, MySQL, Oracle Database, PostgreSQL, and SQLite. The guide covers foundational querying and data modification alongside areas that often produce dialect-specific errors, including data types, conversions, regular expressions, window functions, and pivoting. This edition also acknowledges contemporary analytical workflows by adding material on connecting Python and R to relational databases and a task-oriented How Do I section. The result is best understood as a desk-side tool: a concise source for translating an intended database operation into usable, platform-aware SQL.
