FileExporter Attachement export - Need to filter on Cases fields

[SupportGuy]

Hello,

We are using the ticketing module to manage our support cases.

We are migrating to another external application and want to retrieve attachment from a set of cases.

I know on which Case field to make a filter, but up to now I have'nt succeded in making a filter with FileExporter (modification of "beans.xml" file to modify SQL queries)

I have 2 questions :

1) Is it possible to make SQL join with FileExporter with another table thant "Attachment"?

2) If the response to above question is yes, how could I make a query to filter Attachments depending on Cases fields?

The join I'm trying to do looks like this:
SELECT Case.Type, Attachment.Id, Body FROM Attachment, Case WHERE Case.Type='IPTV' AND Attachment.ParentId=Case.Id

Without this filter atempt, FileExporter is working fine.

May be I'm not in the propoer forum. Should I post this topic elsewhere? Is it that complicated to make simple SQL request in SalesForce?

Hello, I am trying to do something similar, I was wondering if you found an answer?  I am trying to do the same I want to export 1200 attachments from particular account records. I have a custom field on the account which I can reference. If I don't apply this filter I will end up with over 200,000 attachments which neither I or my harddrive needs...
