Readme_Create DataFlow Package Sample
This sample works only with SQL Server 2005 and SQL Server 2008. It will not work with any version of SQL Server earlier than SQL Server 2005.
The Create DataFlow Package sample demonstrates how to programmatically create a package and add a Data Flow. The package that is created in this sample performs the following actions:
- Extracts data from the Products table of the AdventureWorks database.
- Creates a variable to identify the column used to sort the output.
- Saves the results to a flat file destination.
- Executes the package in memory.
- Saves the package for later review.

Running the Sample
If you already know how to locate, build, and install code samples, you can go directly to the section, testing
, and read about how to configure and run this code sample. If you have not used code samples before, you should review the prerequisites first.
Before you run this code sample, ensure that the following conditions are met:
- Open SQL Server Configuration Manager; Click Start, point to All Programs, point to Microsoft SQL Server 2008, point to Configuration Tools, and then click SQL Server Configuration Manager.
- Expand the SQL Server Network Configuration. Select the Protocols for MSSQLServer. Right-click TCP/IP and then click Enable. Stop and restart the service. For more information, see "How to: Set Properties of Integration Services Service Using the Services Snap-in" in SQL Server Books Online. or Open the main.cs file, and replace the localhost value given to the Source parameter in the adventureWorks.ConnectionString with the name of your server.
- The code sample and its associated sample data must first be installed to the local hard disk. For more information, refer to "Installing and Compiling Integration Services Programming Samples" in SQL Server Books Online.
- You must have attached and have administrative permissions to the AdventureWorks database. For more information, see "Installing AdventureWorks Sample Databases and Samples" in SQL Server Books Online. To compile the coding samples, you will need .NET Framework SDK 2.0 or Microsoft Visual Studio. You can obtain .NET Framework SDK free of charge. See the Books Online topic, Installing the .NET Framework Documentation.
If the code sample was installed to the default location, the sample is located in the following directory:
C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Programming Samples\Control Flow\CreatePackage Sample
The C# solution for the code sample is located in the CS directory, and the Visual Basic solution is located in the VB directory.
For information about the two-step process required to install the samples, see Considerations for Installing SQL Server Samples and Sample Databases
Building the Sample
If you have not already generated a strong name key file, use the following procedure to generate this key file.
To generate a strong name key file
- To open a Microsoft Visual Studio command prompt, click Start, point to All Programs, point to Microsoft Visual Studio 2008, point to Visual Studio Tools, and then click Visual Studio 2008 Command Prompt.- or -To open a Microsoft .NET Framework command prompt, click Start, point to All Programs, point to Microsoft .NET Framework SDK 2.0, and then click SDK Command Prompt.
- At the command prompt, use the change directory (CD) command to change the current folder of the Command Prompt window to the Samples folder. The key file that you create in this folder will be used by all Microsoft SQL Server code samples. Note: To determine the folder where samples are located, click Start, point to All Programs, point to Microsoft SQL Server 2008, point to Documentation and Tutorials, and then click Samples Directory. If the default installation location was used, the samples are in <drive>:\Program Files\Microsoft SQL Server\100\Samples.
- At the command prompt, run the following command to generate the key file:sn -k SampleKey.snk Important: For more information about the strong-name key pair, see "Security Briefs: Strong Names and Security in the .NET Framework" in the .NET Development Center on MSDN.
To build the sample
- Open Microsoft Visual Studio 2008.
- From the File | Open menu, click Project and open the solution (.sln) for the desired sample, which is CreatePackageCS.sln from the CS folder or CreatePackageVB.sln from the VB folders, depending on the language you want.
- Click Build / Build CreateTask<lang> on the menu.
Testing the Sample
When the code sample is run, the package that is programmatically created is executed in memory and is saved to the local computer.
You can review the saved version of the package created by this code sample by opening the package in SSIS Designer. For more information about how to open a package in SSIS Designer, refer to the topic, "How to: Add an Existing Integration Services Project to a Solution," in SQL Server Books Online.
The package is saved to the following location:
C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Programming Samples\Control Flow\CreatePackage Sample\<language>\CreatePackage\bin\Debug\SampleRuntimePackage.dtsx
The results created by the package are saved to the following location:
C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Programming Samples\Control Flow\CreatePackage Sample\<language>\CreatePackage\bin\Debug\SampleRuntimeData.txt
You can verify that the package has executed successfully by examining the results in the destination flat file. The column specified by the SortColumn
variable determines how the results are sorted. Subsequent running of the sample will overwrite both the saved package and the previous results in the flat file.
During execution, information about package status, including the number of rows written, is sent to the console. The following is an example of the information that is output to the console.
Description: "component "FlatFileDestination" (221)" wrote 504 rows.
