how to compare date which date is greatest date with example
can i use to_char to compare date
SELECT eno, ename, GREATEST (TBLE.MAX1, TBLE.MAX2) recent_date "
FROM (SELECT TBLA.eno, TBLA.ename, "
MAX (TO_CHAR (TBL.date1, 'MM/DD/YYYY HH24:MI') "
) MAX1, "
MAX (TO_CHAR (TBL.date2, 'MM/DD/YYYY HH24:MI') "
) MAX2 "
FROM dual TBL, dual2 TBLA
in above query if any one of the date having null value then recent_date is showing 'null'
and also it showing wrong value
example
date1='08-22-2009' and date2='01-23-2010' then it showing wrong recent_datel ike='08-22-2009'
as according my knowledge it is comparing with month it sholud not be like this wat i have to do pls explain with example my o/p should come for recent_date like =''01-23-2010''
