如何更正以下 SQL 脚本？

Question

我被分配根据我一周前研究并重新创建的 ERD 在 SQL 中创建一个数据库。我正在使用这个名为“Oracle SQL Developer”的应用程序，并尝试了解如何创建表、主键、外键、序列、视图等。我在开发人员身上测试了我的草稿，他们不断出现以下错误： [在此处输入图片说明][1]

[1]:https://i.stack.imgur.com/vk0cu.png这是由于部分识别规则导致的一些语法错误。

其他错误包括缺少右括号、具有多个主键的表等。到目前为止，这是我在启动数据库方面的最大努力：

/* CREATE A TABLE FOR CUSTOMER INFORMATION FROM THE GREETING CARD CUSTOMIZATION APPLICATION */
CREATE TABLE CUSTOMER
(CUST_EMAIL VARCHAR(10) PRIMARY KEY,
CUST_NAME VARCHAR(10) NOT NULL,
CUST_PHONE NUMERIC(10) NOT NULL,
CUST_ADDRESS VARCHAR(10) NOT NULL,
CUST_CITY VARCHAR(10) NOT NULL,
CUST_STATE VARCHAR(10) NOT NULL,
CONSTRAINT PK_CUSTOMER PRIMARY KEY (CUST_EMAIL)
);
/* CREATE A TABLE FOR GREETING CARD AND ENVELOPE ORDER INFORMATION */
CREATE TABLE PRODUCTS
(ORDER_NO NUMERIC(10) PRIMARY KEY,
CUST_EMAIL VARCHAR(10) FOREIGN KEY,
TRACK_ID NUMERIC(10) NOT NULL,
CONF_NO NUMERIC(10) NOT NULL,
ORDER_DATE DATE(10) NOT NULL,
SHIP_DATE DATE(10) NOT NULL,
CONSTRAINT PK_PRODUCTS PRIMARY KEY (ORDER_NO)
CONSTRAINT FK_PRODUCTS_CUST_EMAIL FOREIGN KEY (CUST_EMAIL) REFERENCES CUSTOMER);
/* CREATE A TABLE FOR PAYMENT INFORMATION */
CREATE TABLE PAYMENT
(PAY_ID NUMERIC(10) PRIMARY KEY,
ORDER_NO NUMERIC(10) FOREIGN KEY,
CARD_TYPE VARCHAR(10) NOT NULL,
PRICE NUMERIC(10) NOT NULL,
PAY_DATE DATE(10) NOT NULL,
PAY_CONF INTEGER(10) NOT NULL,
CONSTRAINT PK_PAYMENT PRIMARY KEY (PAY_ID),
CONSTRAINT FK_PAYMENT_ORDER_NO FOREIGN KEY (ORDER_NO) REFERENCES PRODUCTS);
/* CREATE A TABLE FOR PRODUCT DELIVERY INFORMATION */
CREATE TABLE DELIVERY
(DEL_ID NUMERIC(10) PRIMARY KEY,
ORDER_NO NUMERIC(10) FOREIGN KEY,
SHIP_DATE DATE(10) FOREIGN KEY,
DEL_DATE DATE(10) NOT NULL,
STATUS VARCHAR(10) NOT NULL,
DEL_MODE VARCHAR(10) NOT NULL,
INVOICE_NO INTEGER(10) NOT NULL,
CONSTRAINT PK_DELIVERY PRIMARY KEY (DEL_ID),
CONSTRAINT FK_DELIVERY_ORDER_NO FOREIGN KEY (ORDER_NO) REFERENCES PRODUCTS
CONSTRAINT FK_DELIVERY_SHIP_DATE FOREIGN KEY (SHIP_DATE) REFERENCES PRODUCTS);
/* CREATE A TABLE FOR RECIPIENT INFORMATION */
CREATE TABLE RECIPIENT
(STREET_ADDRESS VARCHAR(10) PRIMARY KEY,
NAME VARCHAR(10) NOT NULL,
CITY VARCHAR(10) NOT NULL,
STATE VARCHAR(10) NOT NULL,
ZIP INTEGER(10) NOT NULL,
CONSTRAINT PK_RECIPIENT PRIMARY KEY (STREET_ADDRESS)
);

如果应用正确地说我遗漏了一些括号，我应该把括号放在哪里？我什至在哪里有多个主键，我如何改写我的行以减少它们？如何将我的规则从部分认可变为完全认可？

这是针对关系数据库系统的大学项目。我只需要创建一些表、主键和外键，以便允许我创建序列。

Answer 1

• DATE 和 INTEGER 没有精度。
• 声明 PRIMARY KEY 内联或外联，但不能同时声明。
• 外键也是如此（内联外键需要 REFERENCES 关键字，而不是 FOREIGN KEY 关键字）。
• VARCHAR 会更好VARCHAR2
• FOREIGN KEY 不能引用非主键、非唯一列（即 SHIP_DATE）。虽然您可以在 ORDER_NO 和 SHIP_DATE 上创建一个 UNIQUE 复合键并引用它（下面的示例）；从DELIVERY 表中完全删除SHIP_DATE 可能会更好（然后您不需要外键）并将其保存在一个表中，以便表处于第三范式。如果您希望信息显示，则使用ORDER_NO 外键JOIN 表。
