SQL99 saith:
g) implementation-defined: Possibly differing between SQL- implementations, but specified by the
implementorfor each particular SQL-implementation.
h) implementation-dependent: Possibly differing between SQL- implementations, but not specified by
ISO/IEC9075, and not required to be specified by the implementor for any particular
SQL-implementations.
Behavior of nondeterministic functions falls in the second category ...
