Thank you for advice. In this case it's a flat file. I could start a new thread but since I've got your ear, I ran into another situation where I had to use a merge join with a SQL query and flat file. My Merge Join was in error because it the flat file wasn't sorted, so I had to throw a sorted between source and merge join. In this case the flat file was already in sorted order. Question: is there a what to tell SSIS that the flat file is already sorted to avoid having to add the Sort Transformation.
It's possible. Have a look here
for more detail than I can type out, particularly the section on setting the sort attributes manually.
