A uniqueidentifier in MS SQL is basically a guid. I am generating them via System.Guid.NewGuid().ToString(N") in the Dot Net framework which now returns me a string of 32 characters (hex). Internally I understand it is a 128-bit integer. As an option I could store that in MySql. What data type would that be?
How would one convert to binary char(16)? In what documentation would I find this? I do not know enough yet to write a UDF.
