In this course you’ll learn how to write various kinds of code modules using C# code. You’ll learn the details of creating SQLCLR code manually as well as with Visual Studio. You’ll learn about the Sql data types and how using them can avoid data conversion issues. Most of the code you write will use basic ADO.NET for data access, but there is a special context connection you need to make to the database where the code is executing. I’ll take a close look at creating triggers and user-defined functions, then will explore the security issues of running SQLCLR code in the SQL Server process, and how to make it work. The course wraps up with some recommendations about how to decide whether to use T-SQL or SQLCLR code to create different kinds of code modules.

This course assumes that you have a basic familiarity with the concept of relational databases and a basic understanding of what SQL Server is and the high-level tools in it, as well as how to create and manage objects using Management Studio. You should also have a basic understanding of how SQL Server implements security, including its authentication and authorization schemes, and how to assign permissions on securable objects to principals. You should know the fundamentals of Transact-SQL to write queries to retrieve and update data, and how to execute scripts using the query editor in Management Studio. It will be very helpful, but not absolutely necessary, to have experience with .NET development using Visual Studio 2010 or 2012 for the portions of the course that deal with SQLCLR development. The .NET code included in this course is written in C#, but if you prefer Visual Basic it should be fairly easy to convert the code.
