Difference between VARCHAR & NVARCHAR using data type code

472553Nov 29 2005 — edited Apr 1 2008

I am tryin to retrieve metadata from Oracle using OCI in my code written in C#. It has been specified that VARCHAR & NVARCHAR has same data type code, both having 1 (same goes for CHAR & NCHAR). How to distinguish between the two when we can not have different codes or is there any way to have different code values?

Thanks & Regards
Mohit
