If you take of the where clause, you get the same result. I don't think this answers the question.

SQLWKS> select 'IT DOES' from dual
     2>
     3>

'ITDOES

IT DOES
1 row selected.

Try running:

select 'IT DOES' from dual where 2 = '02';

I guess that SQLPlus is doing an implicit data conversion.

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.
