Okay you guys are silly. I have probably a stupid basic question to ask.
How important is it to store data (let's say state codes, county codes with
leading zeroes as character versus numeric). What is the standard out
there? Does '02' mean the same thing as 2 for state code if you are
consistent throughout your warehouse or do we need to consider other
datasets out there that might be linked maybe sometime in the future? Can I
leave it as is numeric and create materialized views with it padded or
should I bite the bullet and reload into char/varchar2 datatypes?

Yeah, that's a common misconception. You actually have
to prop the book on your forehead since English flows
to the left and downwards. I have heard that Chinese
flows from right to left and upwards or something
though - you might consider taking it up as a new
language if you are set on the underpillow method of
knowledge transfer.
