Dynamic SQL Using OPEN FOR in Oracle PL/SQL

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;
