Well you can, but you wouldn't want to. Just do the logic yourself by seeing
if the grouping column has changed, if it has, you've moved onto the next
group.

Well that's okay then. But I was HOPING you'd tell me you had a way to group
using cfloop darnit!
Well you can do it...but it's not that efficientrole your own code that
keeps track of the LAST loops value of the field you want to group onwhen
LAST value is not equal to current value
First, thanks to all who communicate via cf_talk. I have learned alot about

I prefer CFLOOP for all my query looping needs (even when I'm
outputting) assuming I don't need the grouping provided by CFOUTPUT.
I don't know if it's more efficient, but I think it makes the code
easier to read.

IIRC, it doesn't matter anymore in terms of speed with CF6+
As a matter of personal preference, if there's no output I use a loop.
If there *is* output and I am using a loop I make sure I put the
cfoutputs outside the loop, but again I don't believe that makes any
difference unless you are on CF

You could just turn on debugging and compare the execution times of both.

Just use a conditional loop which is not over the query as a query, but

Eek, what about cfoutput group=? And what about page includes, those
would be out of the question (including a page with another cfoutput
without a group parameter would throw an error). This coding method has
quite a few consequences
with a query attribute IS easier to use if it suits your needs)

Structure your ColdFusion code with Fusebox. Get the official
ofcourse cfoutput,
that's why it doesn't allow alot of tags to be typed into it.
it's much more faster then CFLOOP, which lets you specify every cf tag you
want (CFMAIL, for example)

No question on that one, CFOUTPUT beats CFLOOP by a long shot, however
sometimes you have to use CFLOOP for things, like if you wish to have a
CFQUERY tag in your CFOUTPUT statement which wouldn't be possible, you'd
have to use CFLOOP
