My app runs on all my companies PCs every month a scan is performed and
the resulst are stored in a database. So the first time a scan is
performed for any PC it will be an insert, but after that it will
always be an update. I tried using openxml in my insert statement but
kept getting an error stating my sub query is returning more than one
result... So since I couldn't do it that way I'm trying this method.
All the relevent openxml is there I just couldn't figure out how to
insert each column using it. If you have any suggestions I'm open to
give it a try.
