I read someplace that the CVS version may support it. Unfortunately,
gborg seems to be down for the past day or so. Looking through the
code, I see things like:
while (x_rset.next()) {
x_rset.previous()
function_that_calls_next(x_rset)
}
Is there a better way to do this? With result pointers from other
languages, like perl, python, php, I know the size of the result so I
can choose the type of loop I want to use. Is there a better way to
loop through a result set and have a another function call next?
