Hello,
I have been searching this newsgroup and trying some code
for a few hours but so far have been beating my head against
a wall it seems.
I need to get the greater value of two date fields, one of which
might be null. I've tried using greatest(date1, nvl(date2,0)) and
select greatest(date1, decode(date2,date2,null,0)) but neither are
working since dates and numbers are not the same datatypes. I've
been trying to find out how to convert a date to a simple number
but cannot find that either. I think that Oracle's starting date
is Jan 01, 1970; do I have to do something like this :
GREATEST(date1, nvl(date2, to_date('01-JAN-1970')) ?
That looks really ugly to me :)
Any help would be appreciated. Thanks!
