Looks promising, I'm gonna try it right now.

One thing I forgot to mention is, I need this total to be one field in the resulting cursor and there will but other fields too, like this:

JobNo Total
===== ==============
124345 12,510.65
643328 52,710.83


Like this:

Select Job.JobNo, (What Naomi said) as Total from Job where job.status='Active'

Will that work?
