Oracle：对象关系数据库，如何用外键插入表值？

Question

实际上，我有两个表 Branch 和 Account_table，我想插入带有外键 (bID) 值的 account_table 值，该外键值是分支表 (bID) 中的主键，但在插入值时出现错误。以下是我的代码。

create type bank_branch as object(
bID varchar2(10),
street varchar2(20),
city varchar2(20),
zipcode varchar2(10),
bPhone varchar2(20))
not final
/
create table branch of bank_branch(
primary key (bID),
/
insert into branch values(
'601','XYZ Street','Orlando','OR112AB','024771169');
/
insert into branch values(
'620','Terrace Road','California','CL229JH','548711131');
/
insert into branch values(
'630','Miami Street','Miami','M21334A','9665411211');
/

create type account_type as object(
accNum int,
accType varchar2(15),
balance number,
bID varchar2(10),
interest number,
overdraftLimit number,
openDate DATE)
/
create table account_table of account_type(
primary key (accNum),
FOREIGN key (bID) REFERENCES branch(bID));
/
insert into account_table 
select 'bID', b.BID
from branch b
where b.BID = 601,
'1001','current','630.87','0.009','400','10-Sep-14');
/

谢谢。

我使用了与您相同的代码。只有插入语句不同。对我来说效果很好。
