When I remember right (check the sources in "Shared/DC/ZRDB/DA.py"),
exceptions are not standardized by Z SQL Methods or (most)
Database adapters.

This means you will see most likely the exceptions of the Python-database
interface library.
These should be standardized. Consult the Python DB-API specification.
