Can I access the values from the dataset that has been passed to For each loop container outside for each loop container in SSIS 2012
HI!
I have a select statement that gets a list of columns from a table and this dataset is passed to a for each loop container and the each column is assigned to a variable created at the package level.
The question is, can the value of these variables be accessed outside the for each loop container. If so, what values do they hold? Is it the most recent value?
If my for each loop container fails, I should update a column in a table based on the value of a column that has been passed and is being accessed in a for each container.
Any code/logic/examples are greatly appreciated!
Thanks a million in advance.

Have you tried Script task. Seems like you have a complex business req. for these kind of things Script task is the best option.

Not sure! how the script task would solve the problem. I'm trying to access the variables that have been assigned from an object dataset passed to a for each loop. I'm trying to access them outside the for each loop container. I'm not able to access them outside the for each loop, is there any property I'd need to set?
You should be able to access the variables anywhere within the scope in which they are defined. They should contain the last values assigned to them, although you will need to test and see exactly what that is after exiting the loop.
If the variables are defined at the scope of the For Each container then they will not exist outside that container. Package level variables, on the other hand, will be available anywhere in the package.
You can use the Variables window to see the scope of variables, and to move them from one scope to another.

Good Suggestion from Megan. Try if this works for you.

Hi! Megan,
Thank you very much! But here's what happening!
I have a SQL statement in the execute SQL task, that pulls a list of files that start with say 'ABC' and today's date. At any given time, the SQL statement pulls atleast 4 files. This dataset is passed to a FOR EACH LOOP ADO enumerator and then if the package fails in any part of the for each loop container it is supposed to insert rows into a table saying failure on the file that's being currently looped through, if a row does not already exist in the table, for that file and if exists update. When I try inserting rows for failure on a file, it is inserting the name of the next file or randomly any of the 4 files, other the name of the current file. If I just try updating instead of inserting, if the row does not exist, it does nothing or updates a row that was existing with the maximum date.
Is there any property I should be setting or is there anything that I'm missing.
Greatly appreciate your help! It's very urgent!
Best Regards,
Amukta

There should be some point within the For Each loop, such as at the beginning of an iteration, where you have the name of the file that should appear in the error output, should the current iteration fail. Can you copy that value to another variable that is outside the scope of the For Each container and available to the error handling component, and that is not otherwise updated each iteration?

HI! Megan,
I've tried that, but looks like it doesn't seem to work.

Thanks Pawan for your input as well! But I'm not sure, how it can be handled in a script task outside the for each loop container and it resolves this issue.
