其他对象PL SQL中的初始化对象

Question

我有以下对象：

TYPE o_seat IS OBJECT
(
    seat_id VARCHAR2 (8 BYTE),
    seat_category_name VARCHAR2 (32 BYTE)
)

以及以下对象：

 TYPE m_seats IS TABLE OF o_seat;


TYPE o_row IS OBJECT
(
    row_no NUMBER (2, 0),
    seats_array m_seats
)

我初始化对象：

   v_row   o_row := o_row (NULL,NULL); 

如何在v_row中初始化seat_array？

Answer 1

类似的东西：

o_row (12,m_seats(o_seat('x','y'),o_seat('y','z')) )

Answer 2

DECLARE
v_row   o_row := o_row (
                        '1',
                        m_seats(
                                o_seat('Seat1','Elite'),
                                o_seat('Seat2','Premium')
                                )
                        );
BEGIN

FOR I IN 1..v_row.seats_array.COUNT LOOP
        DBMS_OUTPUT.PUT_LINE('Row :'||v_row.row_no||
                            ' Seat: '||v_row.seats_array(I).seat_id||
                            ' Category: '||v_row.seats_array(I).seat_category_name);
END LOOP;
END;
