Unfortunately, Oracle does not provide a native UUID data type. As such, you'll often see RAW(16) or VARCHAR2 used to store GUID/UUID data. As for using it from ADO, I've never had a problem.

I have found in the past that ADO will not automaticity convert GUID columns in a dataset to/from RAW(16) or VARCHAR2 columns in a oracle database.

Ian, you are correct, I had to do the conversion. While I haven't used it in awhile, I don't believe there is any automatic conversion.
