Raymond is right (of course), you should be able to write your app in
such a manner that it is portable, but if you must know which database
you are using, then use cftry/cfcatch around two queries - one which
works in MS SQL only, and one which works in MySQL only, whichever one
doesn't fail is the database in force, so set a variable based on that.
You're on your own with the proprietary SQL though.
Good Luck
