Microsoft SQL Server 2012 Integration Services: An Expert Cookbook

Overview of this book

SQL Server Integration Services (SSIS) is a leading tool in the data warehouse industry - used for performing extraction, transformation, and load operations. This book is aligned with the most common methodology associated with SSIS known as Extract Transform and Load (ETL); ETL is responsible for the extraction of data from several sources, their cleansing, customization, and loading into a central repository normally called Data Warehouse or Data Mart.Microsoft SQL Server 2012 Integration Services: An Expert Cookbook covers all the aspects of SSIS 2012 with lots of real-world scenarios to help readers understand usages of SSIS in every environment. Written by two SQL Server MVPs who have in-depth knowledge of SSIS having worked with it for many years.This book starts by creating simple data transfer packages with wizards and illustrates how to create more complex data transfer packages, troubleshoot packages, make robust SSIS packages, and how to boost the performance of data consolidation with SSIS. It then covers data flow transformations and advanced transformations for data cleansing, fuzzy and term extraction in detail. The book then dives deep into making a dynamic package with the help of expressions and variables, and performance tuning and consideration.

The Script Component as a Destination


Writing data at non-ordinal destinations and in special formats creates a need for some custom destinations in the Data Flow. The Script Component as Destination will help SSIS Developers get rid of such problems.

In this recipe, we read some data rows from a database query and load them into a text file destination in a specific format as shown here:

NationalIDNumber
FirstName|LastName|Gender|MaritalStatus
JobTitle;HireDate;DepartmentName;DepartmentGroupName;StartDate;EndDate

The first data row should have NationalIDNumber, the second data row should have personal information that's delimited by a vertical line ( | ), and finally the third row has professional information delimited by a semi colon ( ; ). Each data stream row will be separated into three output rows with different formatting. The regular Flat File Destination cannot handle this format of output, so we handle this problem using a Script Component as Destination.
