Course description

You can add script to an Integration Services package in two main ways, both of which you’ll learn about in this course. First you’ll learn how to use the Script task to add script to a package’s Control Flow. Then you’ll learn how to use the Script Component to add script to a package’s Data Flow. These two components are quite different. The Script task usually executes once in the package, or perhaps once per loop in a looping container. The Script Component executes once per row in the Data Flow, and may end up executing millions of times each time the package executes if there is that much data to process. This is why there are separate components for the Control and Data Flows: the requirements of each are quite different. As a result, the code you’ll write for each is quite different, as you’ll learn in this 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 data and join data from multiple tables, and how to execute scripts using the query editor in Management Studio. You must also know how to connect to an instance of SQL Server 2012 or 2014 using the various connection dialog boxes in Management Studio and development tools. It will be very helpful, but not absolutely necessary, to have experience with .NET development using Visual Studio 2013 or later for the portions of the course that deal with SQL Server Data Tools (which is a lot of it). At the very least, we’ll assume that you are well familiar with the Visual Studio user interface. This course assumes no prior knowledge of SQL Server Integration Services beyond what is covered in the previous SSIS courses.
