This also fixes the cursor system to abandon iterators that will not produce meaningful results since the variables are all unknown types. This creates a weird behavior that existed in previous releases and we are keeping here for backwards compatibility. If a subquery referenced a field that didn't exist in the subquery, it will return nothing. But, if there are two subqueries and one of them has the field exist and the other doesn't, the second will return all null values.
