uniqueidentifier is used to store Global Unique Identifiers (GUID).  For example, the Unique ID's that are stored in your system's registry when a DLL is registered.
In order to fill it, you can try two things:
1) Use the NEWID function.
    Example:
       insert into <tablename>(<columnname>)
       values(newid())

2)  You insert a string with the following format:

xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, in which each x is a hexadecimal digit in the range 0-9 or a-f.
For example, 6F9619FF-8B86-D011-B42D-00C04FC964FF is a valid uniqueidentifier value.
