Well this is not that novel but might be worth including we use external
tables as our "staging" tables for our data warehouse; It saves us from
duplicating space as we can manipulate the data directly from the flat file
and it allows us to do it all in one pass rather than two.

external tables to read archive data.
users normally always want the data even though they'll never actually use
it .
We've moved some data to flat files and given them views to access the data.
works like a charm.
Saved a lot of database apace and maintainence.

Dear list,
Due to a presentation I have promised to give, I am gathering ideas on novel uses for external tables.
I already have 2 good examples to work with, but it would be nice to have some more to work with.
What I already have:
Using external tables to muck about with the alert.log and trace files.
See http://www.dbazine.com/still1.shtml if interested in that.
Along similar lines is using external tables to read trace files. There's a bit of a twist to that one though, as the trace files have extra markers in them, and the SQL to query them uses analytic functions to group the data.
So, any other novel uses I should consider?
Thanks,
Jared
