This book does exactly what it says on the tin. A really clear and well written introduction to T-SQL. I knew a bit of SQL from Access (mostly using the query builders) and this book was perfect for me. Very quicky you wonder how you ever managed with query builders and you see just how powerful proper SQL is. Read the contents page before buying. This book does not include everything about SQL Server (what book does?) but what this covers it does expertly. Highly recommended.
