    This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its RawEnumerable.enumerator() method directly or by using for (... in ...).
    If an element cannot be cast to type TResult, the Enumerator.current() method will throw a ClassCastException a exception when the element it accessed. To obtain only those elements that can be cast to type TResult, use the ExtendedEnumerable.ofType(Class) method instead.

    Description copied from interface: ExtendedQueryable
    
    Projects each element of a sequence to an Enumerable<TSource> and invokes a result selector function on each element therein. The resulting values from each intermediate sequence are combined into a single, one-dimensional sequence and returned.
    NOTE: Renamed from selectMany because had same erasure as ExtendedQueryable.selectMany(org.apache.calcite.linq4j.tree.FunctionExpression, org.apache.calcite.linq4j.tree.FunctionExpression)
