Greetings,
Thanks Dan, but I searched for, and scoured, that page before asking
my question. It helped with some of the details, but not on the
general approach. I'll try to restate my problem in a better way:
What I want is SELECT statement that references no tables but returns
the days in a given month. I'm now thinking that I might be able to
come up with something using an IN clause and using EXTRACT, but
haven't figured it out yet.
