| Replace Null |
Doing that a dozen times for each fact package over and over is boring, so my collegue Marc Potters developped a Replace Null Transformation (a.k.a. Defaulter Transformation) that can replace null values in several columns at once. We made it a bit more general so it can be used to replace null values for all data types.

Downloads:
You can download a SSIS 2008 and 2012 version on the download page.
BETA2: solved bug that could result in double output.
BETA3: solved bug that could result in value 0 if only one column is selected.
Installation
The installer registers the DLL in the GAC and copies it to the component folder of SSIS (example: C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\). After that you have to close Visual Studio/BIDS because it caches the GAC on startup. (Restart not required for SSDT)
How add the transformation to the toolbox (2008 only)
When you open a SSIS project in Visual Studio/Bids, right click the toolbox and choose "Choose Items...". After this Visual Studio will be busy for a couple of seconds!
 |
| Right click toolbox |
When the Choose Toolbox Items window appears, go to the SSIS Data Flow Items
and search for the newly installed transformation and select it. Click ok to
finish.
 |
| Choose Toolbox Items |
Now the new transformation will appear in the toolbox. Ready to use! Have fun.

| New component added |
