Course description

In this course you’ll learn about transaction concepts and the ACID test that SQL Server uses to protect the integrity of data. You’ll also learn about locking and blocking, and how to avoid these inevitable effects of heavily used relational databases. You’ll see how to use transactions in applications, as well as how to handle compile and run time errors caused by your code. Then you’ll learn about how to take control of transactions and defined them explicitly in your code. Then we’ll wrap with a look at a relatively new feature of T-SQL, structured exception handling that has long been a feature of general purpose programming languages.


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.
