Sharing an SSIS Package between Multiple Projects: A Comprehensive Guide

As a developer, it’s not uncommon to encounter situations where you need to share a component or package across multiple projects. In the context of SSIS (SQL Server Integration Services), this can be particularly challenging due to its unique architecture and requirements. In this article, we’ll explore some possible solutions for sharing an SSIS package between multiple projects, including using an EXE instead of a DLL and leveraging Execute Process Tasks.

Understanding SSIS Packages

Before diving into the solution, let’s quickly review how SSIS packages work. An SSIS package is essentially a collection of tasks, connections, and data flows that are executed by the SSIS engine. These packages can be created using various tools, including Visual Studio, SQL Server Data Tools (SSDT), or even manually using XML files.

When you create an SSIS package, it’s stored in a .dtsx file, which contains the package’s metadata and data flows. Other projects that want to use this package must reference it by including the .dtsx file in their own project’s Solution Explorer.

Using an EXE instead of a DLL

One possible solution for sharing an SSIS package between multiple projects is to create an executable (.EXE) file from the package. This can be achieved using tools like tspackage or SSIS Package Utility.

Here’s an example of how you can create an EXE file from an SSIS package using tspackage:

# Create a new directory for your project
mkdir ssis_package_share

# Navigate to the directory
cd ssis_package_share

# Create a new folder for your SSIS package
mkdir ssis_package

# Copy your SSIS package into this folder
copy /y path\to\your\package.dtsx ssis_package\

Next, run tspackage on your package using the following command:

tspackage /packageonly /targetdir:.\ /languagecode:0

This will create an EXE file in the same directory as your package. You can then reference this EXE file from other projects using an Execute Process Task.

Using Execute Process Tasks

To use the EXE file from other projects, you’ll need to add an Execute Process Task to each project’s Data Flow. Here’s an example of how to do this:

Open your project in Visual Studio or SSDT.
Right-click on your data flow and select “Add” > “Execute Process Task…”
In the dialog box that appears, navigate to the location where you saved the EXE file.
Select the EXE file as the executable file to run.
Configure any additional settings required for your specific use case (e.g., arguments, working directory).

Once you’ve set up the Execute Process Task, you can update your package by updating the DLL or EXE file that it references. This way, if changes are made to the package, they’ll be reflected across all projects that reference it.

Combining Projects into a Single Folder

As an alternative solution, you could combine all the projects into a single folder with different .dtproj files for each project. However, as the question highlights, this approach is not ideal due to the potential for merge conflicts and developer confusion.

If you still want to explore this approach, here are some general steps:

Create a new folder in your solution that will serve as the central location for all packages.
Move the .dtsx files from each project into this shared folder.
Update the package references in each project’s dtproj file to reference the shared package instead.

Conclusion

Sharing an SSIS package between multiple projects can be a challenging task, but it’s not impossible. By using an EXE instead of a DLL and leveraging Execute Process Tasks, you can update your package across all projects with minimal hassle. However, this approach requires some additional configuration and planning upfront.

While combining projects into a single folder may seem like a convenient solution, it’s essential to consider the potential drawbacks and weigh them against any benefits.

In conclusion, sharing an SSIS package between multiple projects is a common requirement in many development scenarios. By understanding how to use EXE files, Execute Process Tasks, and navigating the complexities of package referencing, you can effectively share your packages across different projects and ensure seamless collaboration among developers.

Additional Considerations

When working with shared SSIS packages, it’s essential to consider a few additional factors:

Versioning: How will you manage versioning for your packages? Will you use a unique naming convention or a more formal version control system?
Testing: How will you test your shared packages across different projects and environments?
Security: Are there any security concerns associated with sharing an SSIS package between multiple projects?

By carefully considering these factors, you can ensure that your shared packages are reliable, efficient, and secure.

Best Practices

Here are some best practices to keep in mind when working with shared SSIS packages:

Use a consistent naming convention: Use a consistent naming convention for your packages to make it easier to identify and manage them across different projects.
Keep package versions separate: Keep the version numbers of your packages separate from the build or project versions to ensure that you’re always working with the latest package revisions.
Test thoroughly: Test your shared packages thoroughly in different environments and scenarios to catch any issues before they become critical.

By following these best practices, you can ensure that your shared SSIS packages are reliable, efficient, and easy to manage.
