select <col>
from tab1, tab2
where tab1.id <http://tab1.id/> = tab2.id <http://tab2.id/>
and tab1.datefield between tab2.datefield - 5/86400 and tab2.datefield +
5/86400
(assuming my math is correct on seconds in a day!)

Subject: anyone know how to do a join where the data can be
different
I have two different data sets. They come from two different
feeds.
I have an ID field that I can join on that is the same in both.
However, I have a date field in each. Here is the catch, the dates can
be up to 5 second apart.
So I have
select <col>
from tab1, tab2
where tab1.id = tab2.id
and tab1.datefield is with in 5 seconds of tab2.datefield
anyone know a way to do this without a lot of complex pl/sql?
