Name

tuple_uniqtuple_uniqTupleUniqtuple_uniqTupleUniqTupleUniq — Discard all but one of successive identical elements of a tuple.

tuple_uniqtuple_uniqTupleUniqtuple_uniqTupleUniqTupleUniq discards all but one of successive identical elements from the input tuple TupleTupleTupleTupleTupletuple and returns the remaining elements in UniqUniqUniqUniqUniquniq. For example, if TupleTupleTupleTupleTupletuple contains the values [0,0,1,1,1,2,0,1], the output tuple UniqUniqUniqUniqUniquniq will contain the values [0,1,2,0,1]. It is allowed to mix strings and numbers in the input tuple. To delete really all identical elements of the input tuple, use first the operator tuple_sorttuple_sortTupleSorttuple_sortTupleSortTupleSort.

Exception: Empty input tuple

If the input tuple is empty, the operator returns an empty tuple.
