Only thing to watch out for is that Oracle (as of ver 7, haven't used 8
myself) disables indexes on functions
i.e
select * from my_table where upper(surname) = 'SMITH';
will disable any index on the surname column (I think it also happens if
it's part of a composite index). If it's a problem you could have something
like a SurnameEntered column and a SurnameUpper (which you could use to
search on). You really need to watch out when using the TRUNC function to
strip the time component out of dates that only go in as SYSDATE.
