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.

In the Data Flow Task there are times when there is a need to run an SQL statement. This statement may just do something and not return any result, or may get input values and generate output values.

The OLE DB Command provides a way to execute SQL statements on OLE DB connections to databases. We will try to implement the Update part of the previous recipe's Upsert scenario in this recipe.

Getting ready

The previous recipe should be executed before beginning this recipe.

Execute the following command on the PacktPub_SSISbook database to create the stored procedure for updates in the Person table:

Create PROCEDURE dbo.UpdatePerson 
   @ID nvarchar(10),
   @FirstName nvarchar(50),
   @LastName nvarchar(50),
   @Email nvarchar(50),
   @Url nvarchar(50)
AS
BEGIN
   UPDATE [dbo].[SalesPerson]
      SET [FirstName] = @FirstName
        ,[LastName] = @LastName
        ,[Email] = @Email
        ,[Url] = @Url
    WHERE [ID]=@ID ...
