Subj:   Re: Retrieving the Second Highest Amount
 
From:   Sonje, Zdravko

Megan, you can run two statements and then use union to get desired records.

with this you get second highest record:

     select max(amount), customer from table where (amount, customer) not in
     (select max(amount), customer from table group by customer) and date =
     some_date group by customer

and from this you get record where there is only one:

     select a.* from (
     select max(amount) mymax, min(amount) mymin, customer from table where
     date = some_date group by customer
     ) a
     where mymax = mymin

Thanks,

Zdravko Sonje
