I would expect parsing and splitting your string into fields before
handing it to SQL would be faster than handing it into SQL, then using a
trigger to hack it into 2 fields. This would, of course, at least
partially depend on what sort of language that web service is written
in, if its in some hypothetical horribly inefficient interpreted
language, all bets are off.
Does all your data go through a web service now? if not, what data
path IS it coming from?
