Jiatao Tao commented on CALCITE-4424:
-------------------------------------
Hi [~julianhyde], functions like current_time/current_date may be
deterministic, but rand must not be deterministic, we've met this: CALCITE-4413
and we need a non-deterministic function list, current only
SqlSequenceValueOperator override isDeterministic.
> Complete non-deterministic function
