Mary,

I can't see how distinct can help in this case.  If this is a one time 
requirement you could write the keys and max(date) to a temporary file and then 
select the records from the original file using a correlated subquery to join 
back to the temporary records.  If it is not temporary you should be able to 
create a view and join back to that in the same way.  It may be possible to do 
in one statement using a quantified expression but you would be restricted to 
one column which means you would have to do some concatenating which would 
probably be more trouble than it is worth.

Does anyone know the ins and outs of  'SELECT' and 'SELECT DISTINCT'
keywords? 

I have a file with duplicate records and I want the most recent record to
float(ordering it on a descending date) to the top BUT I also want to select
additional fields  that I don't want SQL to consider when it does the
'SELECT DISTINCT'. Is this possible?
