RE: Another how can I do this in SQL ?

Phone #'s that do not have a matching charge code/group code (there will
be many charge detail records for each phone #)

For example I would want all the phone #'s that do not have a specific
charge code or a group code (i.e. all customers who do not have touch
tone service, this is about 15 different charge codes, Group code=TONE)

Again easy to do if I want all those with tone, still easy but takes 2
passes want a "single" pass approach

:Can you say more? Do you want "charge code/group code that do
:not have a matching phone number"? or "phone numbers that do
:not have a matching charge code/group code"?
