Функция, позволяющая сгруппировать несколько столбцов.
Для столбцов, имеющих типы T1, T2, ... возвращает кортеж типа Tuple(T1, T2, ...), содержащий эти столбцы. Выполнение функции ничего не стоит.
Кортежи обычно используются как промежуточное значение в качестве аргумента операторов IN, или для создания списка формальных параметров лямбда-функций. Кортежи не могут быть записаны в таблицу.
tupleElement(tuple, n), оператор x.N

Выполнение функции ничего не стоит.
