Custom SSIS Component: Rownumber Transformation

Adding a rownumber in a data flow is an often seen activity. This isn't a standard feature of SSIS so you will have to use a Script Component or a Third Party Component for that. My Microsoft.Net Colleague Marc Potters and I created a custom component for that which should make thinks easier for those who have less programming experience.

Rownumber

You can either create a new rownumber column and specify the datatype or use one of the existing columns. In the second part you can specify the start number and in the increment. The startnumber can also be specified by a variable which is for example populated by a query in an Execute SQL Task. The last block if for storing the final rownumber in a variable. However this number will only be available when the data flow task has been finished.

Downloads:
You can download a SSIS 2008 and 2012 version on the download page.

Version 1.1: Added the option to add one increment at the end. This makes it easier to use if you want to continue with that number in the next data flow task.

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.

How add the task the the toolbox
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  Rownumber component and select it. Click ok to finish.

Choose Toolbox Items

Now the new component will appear in the toolbox. Ready to use! Have fun.

New component added
