Query: Hello World!

What I like most about this book is that the authors don't waste time (mine and theirs) with the trivial elements of TSQL such as select, insert, update and delete statements. Instead we get waluable information about how to use complex elements such as IF, WHILE, CURSOR, FUNCTION, new triggers, new data types and XML. But best of all, they showed me how to bring all of these elements together in stored procedures. I'd call this one a must have for SQL Server developers.
