Do I have to use NVARCHAR..? What is Difference between VarChar and Nvarchar(). Please explain about UNIcode as well.

Answer 1

The column type nvarchar allows you to store Unicode characters, which basically means almost any character from almost any language (including modern languages and some obsolete languages), and a good number of symbols too.
