This example illustrates how you can create and use dynamic cursor in Oracle PL/SQL. The example is pretty simple, but I hope you can get the idea and apply it to more complicated cases.

DECLARE  t_cursor IS REF CURSOR;  my_cursor t_cursor;  v_customer RECORD (     customer_id NUMBER(18),	 amount NUMBER(22, 2)  );BEGIN  OPEN my_cursor FOR SELECT customer_id,                             amount                        FROM monthly_sales;  LOOP    FETCH my_cursor INTO v_customer;	EXIT WHEN my_cursor%NOTFOUND; 	dbms_output.put_line(v_customer.amount);  END LOOP;END;
