You can use a SQL SELECT statement to read data from one or more tables in a relational database. This is such a common operation that SQL provides a way to save a SELECT statement as a persistent database object, called a view. In this course you’ll learn how to make use of these views. We’ll start by exploring how to create views, reviewing the syntax and the various options you can use. Then we’ll look at the Management Studio tools that help create views. Next you’ll learn how to create a view with a select statement. A computed column in SQL Server is a column that is computed using an expression that uses other fields in the table, a function, or constant values. You’ll learn how to use these columns virtually store data without duplicating it. Next you’ll learn how to use these special indexes to significantly enhance the performance of queries, whether a query uses the underlying view or not.
Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
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.
