Frequently asked questions
Is a GUID the same as a UUID?
Yes. GUID is Microsoft's name for a UUID. Guid.NewGuid() in .NET produces a random version-4 UUID, exactly like the default here.
Which format does SQL Server use?
uniqueidentifier accepts 36-character hyphenated values, with or without braces, e.g. '6F9619FF-8B86-D011-B42D-00C04FC964FF'. Case does not matter.
Should GUIDs be clustered primary keys in SQL Server?
Random v4 GUIDs fragment clustered indexes. Switch to v7 (time-ordered) here, or use NEWSEQUENTIALID() in SQL Server, to keep inserts sequential.
