Question

以下脚本会产生错误：

CREATE TABLE BOTTLE
(
    Bottle_ID VARCHAR(30) NOT NULL,
    BottleSize NUMBER(10,0) ,
    Shape VARCHAR(30) ,
    GlassColor VARCHAR(30) ,
    BottleInventory NUMBER(10,0) ,
    CostPerBottle NUMBER(5,2) ,

    constraint BOTTLE_PK PRIMARY KEY (Bottle_ID)
);

create table BOTTLE_VENDOR
(
    Vendor_ID VARCHAR(30) not null,
    VendorName VARCHAR(20),
    Vendor_Straddr1 VARCHAR(100),
    Vendor_Straddr2 VARCHAR(100),
    Vendor_City VARCHAR(20),
    Vendor_State VARCHAR(20),
    Vendor_Zip CHAR(5),
    Vendor_Phone VARCHAR(20),
    PrincipalContact VARCHAR(30),       

    constraint pk_BOTTLE_VENDOR primary key (Vendor_ID)
);

create table BOTTLE_ORDER
(
    Bottle_Order_ID VARCHAR(30) not null,
    BottleOrderDate DATE,
    Vendor_ID VARCHAR(30),

    constraint pk_BOTTLE_ORDER primary key (Bottle_Order_ID),
    constraint fk_BOTTLE_ORDER foreign key (Vendor_ID) references BOTTLE_VENDOR(Vendor_ID)
);

create table SHIPMENT
(
    Shipment_ID VARCHAR(30) not null,
    ShipmentDate DATE,
    ReceivedQuantity INTEGER,
    ReceivedDate DATE,
    Bottle_Order_ID VARCHAR(30),

    constraint pk_SHIPMENT primary key (Shipment_ID),
    constraint fk_SHIPMENT foreign key (Bottle_Order_ID) references BOTTLE_ORDER(Bottle_Order_ID)
);

create table BOTTLE_ORDER_LINE
(
    Bottle_Order_ID VARCHAR(30) not null,
    Bottle_ID VARCHAR(30) not null,
    BottleOrderQuantity INTEGER,
    ActualPricePerBottle NUMBER(5,2),

    constraint pk_BOTTLE_ORDER_LINE primary key (Bottle_Order_ID,Bottle_ID),
    constraint fk_BOTTLE_ORDER_LINE foreign key (Bottle_Order_ID) references BOTTLE_ORDER(Bottle_Order_ID),
    constraint fk_BOTTLE_ORDER_LINE2 foreign key (Bottle_Order_ID) references BOTTLE(Bottle_ID)
);

这是完全显示的内容：

错误从第37行开始：命令中约束 - 约束fk_SHIPMENT外键（Bottle_Order_ID）引用BOTTLE_ORDER（Bottle_Order_ID）
  错误报告 -
  未知命令

错误让我发疯，并且不知道如何处理它。

Answer 1

以下行（您发布的最后一行）与您的表定义不符：

constraint fk_BOTTLE_ORDER_LINE2 foreign key (Bottle_Order_ID) references BOTTLE(Bottle_ID)

应该是：

constraint fk_BOTTLE_ORDER_LINE2 foreign key (Bottle_ID) references BOTTLE(Bottle_ID)

＆＃34;未知命令＆＃34;创建外键约束时显示
