需要有关 Oracle 10g Express 版本的帮助

当我尝试在下表中插入记录时，出现错误“ora-03001：未实现的功能”。我找了一整夜，还是没有成功。我使用的是 Oracle10g Express 版本。

create or replace type MajorsType As varray(20) of varchar2(10);

create or replace type studenttype as object (
stuID varchar2(5),
lastName varchar2(15),
firstName varchar2(12),
majors MajorsType)
INSTANTIABLE
NOT FINAL;

create table Student of StudentType (
constraint student_stuID_pk PRIMARY KEY(stuID));

INSERT INTO student values StudentType ('S999', 'Smith', 'John', MajorsType('Math', 'Accounting'));

I got error "ora-03001: unimplemented feature" when I try to insert a record on table below. I've searched all night, still no luck. I'm using Oracle10g express edition.

create or replace type MajorsType As varray(20) of varchar2(10);

create or replace type studenttype as object (
stuID varchar2(5),
lastName varchar2(15),
firstName varchar2(12),
majors MajorsType)
INSTANTIABLE
NOT FINAL;

create table Student of StudentType (
constraint student_stuID_pk PRIMARY KEY(stuID));

INSERT INTO student values StudentType ('S999', 'Smith', 'John', MajorsType('Math', 'Accounting'));

这是一个简单的语法错误：VALUES 子句要求将所有内容都括在括号中：

SQL> INSERT INTO student
  2  values ( StudentType ('S999', 'Smith', 'John', MajorsType('Math', 'Accounting')))
  3  /

1 row created.

SQL>

无论我们传递多个标量值还是单个类型，这都适用。

它不适用的一种情况是使用 RECORD 类型在 PL/SQL 中插入。这与您的情况无关，但我提及它是为了完整性。

插入一个 RECORD 变量看起来像这样

declare
    r23 t23%rowtype;  -- record declaration
begin
    r23.id := 1;
    r23.created := sysdate;
    -- insert using record variable
    insert into t23
    values r23; 
end;

It's a simple syntax error: the VALUES clause requires everything to be wrapped in parentheses:

SQL> INSERT INTO student
  2  values ( StudentType ('S999', 'Smith', 'John', MajorsType('Math', 'Accounting')))
  3  /

1 row created.

SQL>

This applies whether we're passing in several scalar values or a single type.

The one case when it doesn't apply is an insert in PL/SQL using a RECORD type. Which is not relevant to your situation, but I'm mentioning it for completeness.

Inserting a RECORD variable would look something like this

declare
    r23 t23%rowtype;  -- record declaration
begin
    r23.id := 1;
    r23.created := sysdate;
    -- insert using record variable
    insert into t23
    values r23; 
end;
