This should do the work:


select MAX(column)
from yourtable
where column> '1/1/12' and column<'7/31/12' and column is not null
OR
select MAX(column)
from dates 
where column between '1/1/12' and '7/31/12' and column is not null

THIS ONLY SELECTS ONE RECORD.. I NEED THE SCRIPT TO SELECT ONE RECORD FROM EACH NUMBER IN OTHER WORDS AFTER THE SCRIPT IS RUN I NEED TO HAVE THE FOLLOWING DISPLAYED

12/29/2011 C 10102 2/20/2012 2/20/2013 2/20/2012
6/21/2012 C 10344 2/2/2012 2/2/2013 3/1/2012
3/13/2012 C 10711 3/15/2012 3/15/2013 3/15/2012

group by NUMBER
OR
select NUMBER,MAX(column)
from dates
where column between '1/1/12' and '7/31/12' and column is not null
