NEWID() Generation Code

hi,
i want the code for newid() in sqlserver 2000 , if anyone knows about it please send me the code.I need it for my customised application . It will be of great help.
Could you explain what exactly you're trying to achieve? I can guarantee you no one will send you the code.|||If your customized application is managed code, Guid.NewGuid() generates a new GUID.

If your app is native, HRESULT CoCreateGUID(GUID *pguid) does the same thing.

NEWID()

Hi,

Can someone explain the generation method of a uniqueidentifier in the NEWID() function ?

This number is generated using identification number of computer network card and an unique number from the CPU clock. (The network card is unique too)|||

Why do you care?

The uniqueidentifier is guaranteed to be a unique hex identifier. It is not sequential and cannot be used for any other purpose than a unique id of an object or record.

Check out the following topics for description on the Win32API that SQL Server uses for NEWID and NEWSEQUENTIALID. The actual algorithm details can be found on the web.
