Subject:      Re: Comparison across rows

Paul,

great question...ok, lets say i want all of the combinations where
difference is 60 days

in this instance the by group will be id, name, price. if we have multiple
rows for that group then we compare the dates. sample
group     date
101/01/2004
02/25/2004
05/01/2004
