I primarily read this book to see what specifically SQL Server 2005 has as far as CLR integration is concerned. This book was a good overview of all aspects of SQL Server development. It covered T-SQL stored procedures and general SQL queries. From a CLR perspective, it covered the following:
- CLR development (about 12 pages)
- CLR stored procedures (about 20)
- Functions and stored procedures (about 30)
- Advanced topics (about 40)
I guess the point is that there is not much extra stuff you need to know to utilize the .NET CLR in SQL Server 2005.
