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?
