Once a cursor variable is opened with a query statement, it will have the same attributes as a normal cursor and it can be used in the same way a normal cursor too. The following sample script shows you how to loop through a cursor variable:
CREATE OR REPLACE PROCEDURE FYI_CENTER AS
TYPE emp_ref IS REF CURSOR RETURN employees%ROWTYPE;
emp_cur emp_ref;
emp_rec employees%ROWTYPE;
BEGIN
OPEN emp_cur FOR SELECT * FROM employees
WHERE manager_id = 101;
LOOP
FETCH emp_cur INTO emp_rec;
EXIT WHEN emp_cur%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('Name = ' ||
emp_rec.first_name || ' ' || emp_rec.last_name);
END LOOP;
CLOSE emp_cur;
END;
