tuple_selecttuple_selectTupleSelecttuple_selectTupleSelectTupleSelect selects one or more single elements of the tuple TupleTupleTupleTupleTupletuple and returns them with SelectedSelectedSelectedSelectedSelectedselected. At this, IndexIndexIndexIndexIndexindex determines the indices of the elements to select. Thus, IndexIndexIndexIndexIndexindex may only contain integer values (any floating point number within IndexIndexIndexIndexIndexindex must represent an integer value without fraction). Indices of tuple elements start at 0, that means, the first tuple element has got the index 0.
