If I unload only one column from a table and that column is the first
column of the clustering index, will the output DS be in physical order
of the table or in index order? My gut feeling is that it should be in
index order as the unload can be satisfied from the index alone, but I
can't find any confirmation in the documentation. It doesn't appear as
if I can specify an ORDER BY clause in UNLOAD as I could have done with
DSNTIAUL.
