| Multiple Expressions Task |
We, me and my colleague Marc Potters, have created a new cool task to set the values of multiple variables in a single task. You can a either use a value or the Expression Builder.
 |
| Enter a value or use an expression |
 |
| Or use the SSIS Expression Builder |
You can also create variables within the task via a context menu.
 |
| Create variables |
Other features of version 0.1:
- Clearly shows faulty expressions, but you can close the editor without losing it.
- Create new rows to set the value of existing variables.
- Delete rows via the context menu
- Indicator to show that an expression is used

Downloads:
You can download a SSIS 2008 and 2012 version on the download page.
Installation
The installer registers the DLL in the GAC and copies it to the task folder of SSIS (example: C:\Program Files\Microsoft SQL Server\100\DTS\Tasks\). After that you have to close Visual Studio/BIDS because it caches the GAC on startup. Restarting SQL Server Data Tools is not necessary.
How add the task the 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 Control Flow Items and search for the newly installed Multiple Expressions Task and select it. Click ok to finish.
 |
| Choose Toolbox Items |
Now the new task will appear in the toolbox. Ready to use! Have fun.

Bugs or feature suggestions
Please contact me or leave a comment if you have any suggestions or found a bug in this Custom task.
It appears, at first look, that your muti-variable component freezes when used in a for each file container. The second iteration stops at the multi-variable component.
ReplyDeleteI've had a similar issue using a ForEach loop. The task worked the first time, but on the second time, it didn't work. It throws an error for each expression one at a time (with like 30 sec in between). The error was "The expression for variable '[variable name]' failed evaluation. There was an error in the expression." I know this is definitely not the case as (1) it works the first time, and (2) the package works using the standard Expression Task.
