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.

Executing T-SQL commands: Execute SQL Task


One of the most useful tasks in SSIS is the Execute SQL Task. This task can be used for executing every T-SQL command on an underlying database. Underlying databases can vary because there is a wide variety of connection managers that have SQL Task support. In this recipe, we will see some of the most useful scenarios such as the execution of T-SQL commands and fetching results, or passing input and output parameters.

How to do it...

  1. Open SSTD and create a new Integration Services Project type at the following location: C:\SSIS\Ch02_Control Flow Tasks\ and name the project R01_Execute SQL Task.

  2. Rename the package as P01_SingleRowResultSet.dtsx.

  3. From the SSIS menu select Variables; the Variables pane will appear. Create a new variable with the Name RowCount and Data type Int32 at the package Scope.

  4. In the empty package's Control Flow tab, drag-and-drop a Execute SQL Task from the toolbox under Favorites into the Control Flow.

  5. Double-click on Execute SQL...
