Ah, ok. I was concerned about removing this procedure from SP. Now, the PK field has GUID() as default value. If I want to use class procedure, say, this.CreateGUID(), then I would need to adjust every single insert command to include PK field in it.

That I can do. I also can keep HexToChar and BinToHex procedures in SP...
