oracle中一种集合类型//不知道其他数据库有没有

create type address_type as object

( city varchar2(15),

zip varchar2(5));

/

create type bbb as table of address_type;

/

create table ccc(

id integer primary key,

name varchar2(15),

address bbb)

nested table

address

store as

nested_addresses;

添加

insert into ccc values( 1, 'hi',bbb( address_type ('bki' , 't'),

address_type('bhy' , 'y')

)

);
