尝试运行通过 Oracle 11g 编写脚本

Question

我正在尝试运行 SQL 在 Oracle 11g Express 版本中创建表的语句。这是我的 SQL 代码：

    CREATE TABLE STORE
    (
    StoreID INT PRIMARY KEY,
    StoreName VARCHAR2(30) NOT NULL,
    City VARCHAR2(30) NOT NULL,
    Country VARCHAR2(30) NOT NULL CHECK Country in ('China','Egypt','United States','Spain','New Zealand','Mexico','Africa'),
    Phone VARCHAR2(30) NOT NULL,
    Fax VARCHAR2(30),
    Email VARCHAR2(50) UNIQUE,
    Contact VARCHAR2(30) NOT NULL,
    UNIQUE (StoreName, City)
    );

    CREATE TABLE PURCHASE_ITEM
    (
    PurchaseItemID INT PRIMARY KEY,
    StoreID INT NOT NULL REFERENCES STORE(StoreID) ON DELETE CASCADE ON UPDATE CASCADE,
    "Date" DATE NOT NULL,
    Description VARCHAR2(30) NOT NULL,
    Category VARCHAR2(30),
    PriceUsed NUMBER(15, 2)
    );

    CREATE SEQUENCE pur_seq
    START WITH 500 
    INCREMENT BY 5;

    CREATE OR REPLACE TRIGGER Purchase
    BEFORE INSERT ON PURCHASE_ITEM
    FOR EACH ROW
    BEGIN
    SELECT pur_seq.NEXTVAL
    INTO :new.PurchaseItemID
    FROM dual;
    END;

    CREATE TABLE SHIPPER
    (
    ShipperID INT PRIMARY KEY,
    ShipperName VARCHAR2(30) NOT NULL,
    Phone VARCHAR2(30) NOT NULL,
    Fax VARCHAR2(30),
    Email VARCHAR2(50) UNIQUE,
    Contact VARCHAR2(30) NOT NULL
    );

    CREATE TABLE SHIPMENT
    (
    ShipmentID INT PRIMARY KEY Auto Increment,
    ShipperID INT NOT NULL REFERENCES SHIPPER(ShipperID) ON DELETE CASCADE ON UPDATE CASCADE,
    ShipperInvoiceNumber INT NOT NULL UNIQUE,
    Origin VARCHAR2(30) NOT NULL,
    Destination VARCHAR2(30) NOT NULL,
    DepartureDate DATE,
    ArrivalDate DATE
    );

    ALTER TABLE SHIPMENT AUTO_INCREMENT = 100;

    CREATE TABLE SHIPMENT_ITEM
    (
    ShipmentID INT NOT NULL REFERENCES SHIPMENT(ShipmentID) ON DELETE CASCADE ON UPDATE CASCADE,
    ShipmentItemID INT NOT NULL,
    PurchaseItemID INT NOT NULL REFERENCES PURCHASE_ITEM(PurchaseItemID) ON DELETE CASCADE ON UPDATE CASCADE,
    InsuredValue NUMBER(15, 2) NOT NULL defaut 100,
    PRIMARY KEY (ShipmentID, ShipmentItemID)
    );

它只处理了 4 个语句，我不断收到这些错误消息：

    CREATE TABLE STORE ( StoreID INT PRIMARY K   -   ORA-00906: missing left parenthesis
    CREATE TABLE PURCHASE_ITEM ( PurchaseItemID INT   -   ORA-00907: missing right parenthesis
    CREATE SEQUENCE pur_seq START WITH 500 INCREMENT BY 5   -   ORA-00955: name is already used by an existing object   
    CREATE OR REPLACE TRIGGER Purchase BEFORE INSERT ON PURCHASE   -   ORA-00942: table or view does not exist

我对 Oracle 11g 完全不熟悉。我不确定我是否在其中使用了正确的应用程序来完成我的作业。我只会按照这些说明进行操作：

"For this assignment you are to write scripts to create tables and insert records. In oracle 11g I don’t want you to use the tools to generate the tables, you are required to write scripts to create the tables and records and will need to include the scripts for your submission."

拜托，我做错了什么？

让我总结一下你脚本的问题

首先你必须用大括号括起检查约束，如下所示

  CREATE TABLE STORE
        (
        StoreID INT PRIMARY KEY,
        StoreName VARCHAR2(30) NOT NULL,
        City VARCHAR2(30) NOT NULL,
        Country VARCHAR2(30) NOT NULL CHECK (Country in ('China','Egypt','United States','Spain','New Zealand','Mexico','Africa')),
        Phone VARCHAR2(30) NOT NULL,
        Fax VARCHAR2(30),
        Email VARCHAR2(50) UNIQUE,
        Contact VARCHAR2(30) NOT NULL,
        UNIQUE (StoreName, City)
        );

其次，Oracle 11g中没有ON UPDATE CASCADE所以需要从CREATE TABLE语句中去掉

第三，Oracle 11G 中没有 Auto increment 的列所以请参考此 SO 的解决方法

请通过这些更正让我知道您的问题是否已解决
