A structure that represents a GUID, which maps to the SQL Server uniqueidentifier data type. Any generated GUID is statistically unique. A GUID converts to strings in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, in which each x is a hexadecimal digit in the range 0-9 or A-F, e.g., 6F9619FF-8B86-D011-B42D-00C04FC964FF.
