/***********************************************************************
tquery3.cpp - Similar to tquery1.cpp but uses unquoted parameters.
It's here more for code test coverage than because it shows
something interesting. We've historically had a problem with
tqueries with just one parameter; we cover the quoted case in
resetdb and the other tquery examples, so we get the unquoted
one here.
