LAST is a method that returns the subscript of the last element in a collection.
The syntax for using LAST is as follows:
collection.LAST
collection is the name of a collection.
The following example displays the last element of the associative array:
DECLARE
TYPE sparse_arr_typ IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
sparse_arr sparse_arr_typ;
BEGIN
sparse_arr(-100) := -100;
sparse_arr(-10) := -10;
sparse_arr(0) := 0;
sparse_arr(10) := 10;
sparse_arr(100) := 100;
DBMS_OUTPUT.PUT_LINE('LAST element: ' || sparse_arr(sparse_arr.LAST));
END;
LAST element: 100
