初始化對象，它是在其他物體PL SQL

Question

我有以下對象：

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

及以下對象：

TYPE m_seats IS TABLE OF o_seat; 


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

我初始化對象：

v_row o_row := o_row (NULL,NULL); 

哪有我在v_row中初始化seats_array？

Answer 1

喜歡的東西：

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;
