A SELECT DISTINCT isn't possible in this case, though it's a good idea and something we'd thought of.
The DB we're using is global, and belongs to a different group to the one I work in. It has data stored how they need it for their reporting, not how we need it for ours - hence the need to concatenate data when duplicates occur on one (of our) orderids.
It's for a fairly specific use, actually: we're trying to have their systems interface with ours for reconciliation purposes, and it's proving to be a lot less simple than I originally thought :)
It'd make a lot more sense if the company had data storage standards, as we're all essentially in different areas of the the same business, but that'd make life easy ... *grin*
