Itzik Ben-gan T-sql Fundamentals ((hot))
Key Concept 1: The Declarative Nature of SQL Explain how Ben-Gan contrasts imperative programming (telling the computer how to do it) vs. declarative programming (telling the computer what you want). This is the biggest hurdle for new SQL developers.
With tools like ChatGPT and Copilot generating SQL, why learn fundamentals? Because AI generates average SQL. It often produces LEFT JOIN when EXISTS is faster, or uses SELECT * because the prompt was lazy.
Versions like the 2012 or 2016 editions remain highly relevant for core syntax and theory.
