Overview of this book

ETL is one of the most common and tedious procedures for moving and processing data from one database to another. With the help of this book, you will be able to speed up the process by designing effective ETL solutions using the Azure services available for handling and transforming any data to suit your requirements. With this cookbook, you’ll become well versed in all the features of SQL Server Integration Services (SSIS) to perform data migration and ETL tasks that integrate with Azure. You’ll learn how to transform data in Azure and understand how legacy systems perform ETL on-premises using SSIS. Later chapters will get you up to speed with connecting and retrieving data from SQL Server 2019 Big Data Clusters, and even show you how to extend and customize the SSIS toolbox using custom-developed tasks and transforms. This ETL book also contains practical recipes for moving and transforming data with Azure services, such as Data Factory and Azure Databricks, and lets you explore various options for migrating SSIS packages to Azure. Toward the end, you’ll find out how to profile data in the cloud and automate service creation with Business Intelligence Markup Language (BIML). By the end of this book, you’ll have developed the skills you need to create and automate ETL solutions on-premises as well as in Azure.

Generating an SSIS package with Execute SQL Tasks

Now let's create an SSIS package with some more meat on it. The original SSIS package that I want to generate automatically, DailyETLMain.dtsx, contains multiple tasks within each Sequence Container, such as an Expression Task and Execute SQL Tasks, as shown in the following screenshot:

Figure 10.10 – A screenshot showing DailyETLMain.dtsx

We will begin with the Biml code that was started in the previous recipe and programmatically add precedence constraints, connections, variables, and tasks within each Sequence Container. What we want to accomplish in this recipe is generating an SSIS package with Sequence Containers that will run one after another on success. Each sequence container will contain four tasks: one Expression Task and three Execute SQL Tasks. The resulting package will be one more step toward using Biml to automatically generate a sample DailyETLMain.dtsx SSIS package from the Wide...
