A 10/01/2015
B 01/01/2012
B 04/08/2013
B 01/06/2014
C 01/07/2015


I need to get as result:

Hi vegafacundodaniel,

the answer lies in the subject of your thread ;)

DB2 offers you the max() aggregate function. If you add a 'group by' clause to the query, it will work as desired:

select code ,max(datecol)
from   table1
group  by code
