Jiatao Tao updated CALCITE-4424:
--------------------------------
Description:
Func like RAND doesn't override isDeterministic, these func seems are not
deterministic(the list comes from "isDynamicFunction"):
1. SqlAbstractTimeFunction
2. SqlBaseContextVariable
3. SqlCurrentDateFunction
4. SqlRandFunction
5. SqlRandIntegerFunction
was:
Current RexUtil#isDeterministic only considers SqlOperator#isDeterministic, but
func like RAND doesn't override isDeterministic, but use
isDynamicFunction(org.apache.calcite.sql.fun.SqlRandFunction)
Here the list of isDynamicFunction:
1. SqlAbstractTimeFunction
2. SqlBaseContextVariable
3. SqlCurrentDateFunction
4. SqlRandFunction
5. SqlRandIntegerFunction
> RexUtil#isDeterministic should consider SqlOperator#isDynamicFunction
