在Oracle中创建嵌套表时出错

下面是我创建的表格

CREATE TYPE ft_obj AS OBJECT (
    ftid         NUMBER(5),
    ftlocation   VARCHAR(30),
    country      VARCHAR(10)

    ftid PRIMARY KEY
) OBJECT IDENTIFIER IS PRIMARY KEY;
/

    prodid           NUMBER(6),
    ft_ref           ft_obj,
    proddesc         VARCHAR(50),
    costperitem      DECIMAL,
    labcostperitem   DECIMAL
);
/

CREATE TABLE frod_table OF frod_obj (
    prodid PRIMARY KEY
) OBJECT IDENTIFIER IS PRIMARY KEY;

CREATE TYPE wf_obj AS OBJECT (
    wfid           NUMBER,
    ft_ref         ft_obj,
    wfname         VARCHAR(30),
    taxcode        INT,
    yearlyincome   DECIMAL,
    yearlytax      DECIMAL

    wfid PRIMARY KEY

    jobhours        INT,
    jobhourlyrate   DECIMAL,

    wfid_ref        REF wf_obj

/

ALTER TABLE oprod_ntab ADD (

由于您已经完成了

多级

嵌套，因此在创建表时，您需要两级

存储

以及

嵌套的

表。请参见下面的操作方法

CREATE TABLE prod_objtab OF prod_obj (
    PRIMARY KEY ( prodoid )
) OBJECT IDENTIFIER IS PRIMARY KEY 
NESTED TABLE odetails_ntab STORE AS oprod_ntab ( ( PRIMARY KEY (NESTED_TABLE_ID, mfid )) 
ORGANIZATION INDEX COMPRESS
NESTED TABLE wfusage_ntab STORE AS  XX ) RETURN AS LOCATOR;
