SQL错误 - 缺少关键字

Question

这个查询有什么问题:我收到了以下错误

SQL错误:ORA-00905:缺少关键字00905. 00000 - "缺少关键字"

它在第4行说错误.请指教

CREATE TABLE ORDERS
(
ID INT        NOT NULL,
ord_date    DATE, 
AMOUNT     double,
CUSTOMER_ID INT references CUSTOMERS(ID),
PRIMARY KEY (ID)
);

Answer 1

你错过了添加precision的double数据类型

CREATE TABLE ORDERS
(
   ID INT        NOT NULL,
   ord_date    DATE, 
   AMOUNT     double precision,
   CUSTOMER_ID INT references CUSTOMERS(ID),
   PRIMARY KEY (ID)
);
