Question

此查询错误：我收到以下错误

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

您错过了在precision数据类型

中添加double

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