No matter how you slice it it's too much stuff for such a simple
concept. Here's another slice with TOO much stuff:
select case when next_day(round(sysdate,'MM'),'WEDNESDAY') < sysdate
or round(trunc(sysdate,'MM'),'W')
= NEXT_DAY(TRUNC(sysdate,'MM')-1,'WEDNESDAY')
then next_day(round(sysdate+16,'MM'),'WEDNESDAY')
else next_day(round(sysdate,'MM'),'WEDNESDAY')
end
from dual;

This should fix the flaw:
select CASE WHEN to_char(to_date('09/04/2003','MM/DD/YYYY'), 'DD') <= 6
THEN CASE WHEN to_char(to_date('09/04/2003','MM/DD/YYYY'),
'DY') = 'WED'
THEN to_date('09/04/2003', 'MM/DD/YYYY')
ELSE CASE WHEN
to_char(next_day(to_date('09/04/2003', 'MM/DD/YYYY'), 'WED'), 'DD') > 6
THEN
next_day(last_day(to_date('09/04/2003','MM/DD/YYYY')),'WED')
ELSE next_day(to_date('09/04/2003',
'MM/DD/YYYY'), 'WED')
END
END
ELSE
next_day(last_day(to_date('09/04/2003','MM/DD/YYYY')),'WED')
END
from dual;

Jared,
If you will closely examine the specs, the assumption is not
documented. Therefore, the application code must take into account that
the 1st Wednesday of the month may still be in the future.
select CASE WHEN to_char(to_date('08/07/2003','MM/DD/YYYY'), 'DD') <= 6
THEN CASE WHEN to_char(to_date('08/07/2003','MM/DD/YYYY'),
'DY') = 'WED'
THEN to_date('08/07/2003', 'MM/DD/YYYY')
ELSE next_day(to_date('08/07/2003', 'MM/DD/YYYY'),
'WED')
END
ELSE
next_day(last_day(to_date('08/07/2003','MM/DD/YYYY')),'WED')
END
from dual;
Of course, there is a flaw in this logic. Can anyone spot it?
It's particularly nasty...
