Learn T-SQL from Scratch: A beginner’s guide to T-SQL querying, SQL Server development, performance tuning, and deployment - 2nd Edition

Start your SQL Server and T-SQL journey with a clear, simple, and step-by-step guide that helps you build practical database skills from the ground up. You will learn DDL to create databases, schemas, tables, constraints, and indexes, and DML to retrieve and modify data. You will build advanced querying and analytical skills with joins, subqueries, CTEs, built-in functions, pivot, unpivot, rollup, and ranking and window functions.

You will use T-SQL features including temporary tables, cursors, WHILE loops, CASE expressions, IF...ELSE statements, transactions, error handling, concurrency controls, and isolation levels. You will create stored procedures, views, functions, and triggers; process XML and JSON; improve performance through indexing and tuning; troubleshoot issues; and deploy database solutions.

Updated for SQL Server 2022, this edition covers relevant features and practical topics without promising exhaustive coverage. It expands coverage of built-in functions, pivot, unpivot, rollup, cursors, concurrency concepts, isolation levels, performance tuning, and tips for writing efficient stored procedures.
