What does the COUNT method do?

The COUNT method returns the number of elements currently held by a collection.

Syntax:

collectionname.COUNT

Example:

DECLARE
   TYPE NbrLst IS TABLE OF INTEGER;
   n NbrLst := NbrLst (1,2,3,4,5);
BEGIN
   DBMS_OUTPUT.PUT_LINE(’There are ‘ || n.COUNT || ‘ elements.’);
   n.DELETE(4); — fourth element is deleted
   DBMS_OUTPUT.PUT_LINE(’Now, there are ‘ || n.COUNT || ‘ elements.’);
END;
/
