Folks,
Thanks for your suggestions. Apparently I wasn't clear enough about
what I'm trying to do:
> >

> >
>

>
> select date from xx where to_char(date,'fmdy') = 'wed';
This doesn't solve my problem, as the suggestion above presupposes that
I have a temp table of all possible dates in the range, or
misunderstands that I am trying to find all Wednesdays in column x.
I am trying to list all Wednesdays that are *not* in column x.
This requires me to build a list of all possible Wednesdays (within a
date range), preferably *without* first having a table of all dates in
existance! Some sort of manipulation of the date processor should be
possible, shouldn't it?
