If you have a cursor opened ready to use, you can also use the FETCH statement in a loop to retrieve data from the cursor more efficiently. But you need to remember to use an EXIT statement break the loop when the cursor pointer reaches the end. The script below gives you a good example:
CREATE OR REPLACE PROCEDURE FYI_CENTER AS
CURSOR emp_cur IS SELECT * FROM employees
WHERE manager_id = 101;
emp_rec employees%ROWTYPE;
BEGIN
OPEN emp_cur;
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;
