This approach would seem wrong. If the Windows UUID functions is generating correct values, and those values are stored correctly in the database. Then it seems that the "raw" number and the text representation are not supposed to be match. So the problem is with the UUID to CHAR functions, not with how the value is stored/generated. Your proposal would have Firebird manipulate the stored value to match the text representation, which seems to contradict the RFC. I agree that the fact that the raw and text values would not look the same is a problem, but is not for this project to contradict the RFC. > I also consider better to say it's currently incorrect for Windows too, since > UUIDs nature is to be distributed and may be interchangeable with ones > generated in others platforms. But what is the basis for the interchange, the raw UUID value or the text representation? Both? Your solution expects that it is only the text representation.
