Talend Write into file with dynamic

Hi,

I have to make a tFileOutputDelimited with no rundown of fields or better with a dynamic rundown. That is on the grounds that every cycle the activity makes the question. The question goes to tSalesforceInput and the inquiry result (is a Select) ought to go to a CSV document. The fields and the table change every emphasis, so I can't provide for tFileOutput a rundown I don't know how much fields there are on each question.

Thank You

Hari
