Returns true when the current expression always return the same result for fixed inputs from children. The non-deterministic expressions should not change in number and order. They should not be evaluated during the query planning.
Note that this means that an expression should be considered as non-deterministic if: - it relies on some mutable internal state, or - it relies on some implicit input that is not part of the children expression list. - it has non-deterministic child or children. - it assumes the input satisfies some certain condition via the child operator.
