AW: Data Types

Hi Santosh,  

VARCHAR and VARCHAR2 are pretty much the same, but Oracle has them both to be compatible ANSI types.
The N prefix indicates that you can store multibyte data in these fields
(like Unicode). The reason behind it is,
that you can either have the whole database be Unicode based or you don't and then you'll have to use the N
prefixed datatypes in order to have a Unicode / non-Unicode mix within tables.  

Regards,
Stefan
