Developing SSIS Packages
Quick check
1 . How would you use SSIS to import a file from an fTP server to a SQL Server
table
2. you need to migrate a user-created Access database to SQL Server, but the Data
flow toolbox does not contain an Access source adapter. How do you import this data into SQL Server
3. The Multicast Transformation and the Conditional Split Transformation both can
have multiple outputs. Which transformation would you use if you needed to send rows matching certain conditions out one output and rows matching different conditions out another
4. Describe the transformations you could use to combine data from two different
database tables that exist on two different servers.
Quick check answers
1 . first, you would use an fTP Task to copy the file to the machine on which SSIS
is installed. you can then import the file into a SQL Server table by using a Data flow Task configured with a flat file Source adapter and either a SQL Server Destination adapter or an oLE DB Destination adapter.
2. Although not listed in the toolbox, Access is one of the many database sources
and destinations that SSIS works with. To extract data from Access, you first need to make a package connection to the Microsoft Jet oLE DB Provider. you can then use the oLE DB Source adapter to select the table or perform a custom query.
3. The Conditional Split Transformation lets you define expressions against which
the rows from the source are evaluated. for every row, the expressions are evaluated in order, and a row is sent out the first output when the matching expression evaluates to True. Therefore, any single row can go out only one output. With a Multicast Transformation, on the other hand, all rows go out every output.
4. To combine data from two different database tables that exist on two different
servers, you could use the Merge Join Transformation, which combines datasets by joining the rows across a set of common keys. This transformation allows an inner join, a left outer join, or a full outer join. you could also use a Lookup Transformation to associate data from two sources. The Lookup can cache a table in memory and, through matching columns, can return new columns to the data ow.
Lesson 3: Using Data Flow Adapters and Transformations
case scenario: creating an etL solution
The business development department of Adventure Works has requested that you implement a data mart that it can use to analyze reseller sales against salesperson sales targets. Your first task is to create a series of SSIS packages that move data from the source Enterprise Resource Planning (ERP) system to a data mart database that contains fact tables and dimension tables.
1. 2. 3.
How would you work within BIDS to create SSIS project structures, packages, project data sources, and package connections What transformations would you use, and how would you implement the data flow that loads dimension tables What transformations would you use, and how would you implement the data flow that loads fact tables
chapter summary
Creating SSIS packages involves working with BIDS and creating a new SSIS project. The main object in an SSIS project is a package, which contains the business logic to manage workflows and process data. Within a package, the control flow lets you create tasks and containers, which provide the ability to run process-oriented operations. The Data Flow Task is the second core object (behind the control flow) in an SSIS package, enabling data-processing operations. The data flow uses source adapters, destination adapters, and transformations.
Developing SSIS Packages
chapter 2
Debugging and Error Handling in SSIS
ackage development and implementation goes beyond using transformations to connect sources to destinations. You must also implement error handling and test and troubleshoot your packages as you develop them. SQL Server 2008 Integration Services (SSIS) provides several ways to handle errors at different levels of the SSIS architecture. For example, at the control flow level, you can add a failure constraint that, if an error occurs, redirects the workflow to a specified alternative task. Similarly, in the data flow, if a row causes an error in a transformation, you can send the row out an error path. SSIS even includes event-handling capabilities that let you trap OnWarning and OnError events, and you can have all these events logged to a table or a file for review and troubleshooting. In this chapter, you look at the various capabilities in SSIS for debugging packages during development and for dealing with errors during production execution, including execution logging. You begin by looking at how to configure package transactions and checkpoints and then see how to identify package status, handle task errors, and log your package execution. Last, you learn about data flow error handling and debugging.
