Hello,

What is uniqueidentifier as a data type?

Also what is the data type for setting unique STRINGS ((nchar,
nvarchar), for example to be used for emails and user names in a user
registration system).

SQL Server does not allow me set primary keys for columns where data
types are not INT.

Thanks in advance.
