uniqueidentifier data type in MS SQL 2005

I'm using MS SQL Server 2005 Management Studio Express to create a simple database that will manage customer-specific PDF documents that customers will have access to on the company website. The files will be stored on the server's file system and this database will just manage the links to those documents. I'm building this with MS Visual Studio Web Developer 2008 Express Edition. I'm just building a sample site on my local drive; not production at this point.

If I use the uniqueidentifier data type in a table, how is that unique identifier number generated? Do I have to manually generate it in code when I add an item to that table or is this a GUID that the system generates automatically? Thanks.

yes/no.

let me explain:
no -> you could use the newid() function as default.

however, if you want to retrieve/know the generated value, it will be better if you generate it in your (sql) code for the insert, and return it back to the application code.
