Minor thing, but let me point out…
The message for ORA-62432 seems not quite implemented in 23.26.
The new UUID (V4) can be displayed in hyphened format using RAW_TO_UUID.
And an old SYS_GUID, or a UUID-V7, should(?) results in an error message. That message comes out garbled on the latest container. The mesage on the web-page is correct… (but edited on the 13th of October ;-)
And allow me to make the two more points
point 1: a UUID-V7 would be nice to have, I expect that soon-ish.
point 2: a data-type UUID would also be nice to have..
demo file attached, can be used to reproduce.. (unless it is only my container..)
screenshot… to prove I Did have this phenomena (on my system…)
