ORA-00907: 缺少右括号 .. 当我没有缺少任何括号或拼写错误时 [关闭]

Question

当我运行这个 SQL 时，它给了我这个错误，我想不通

CREATE TABLE PAYMENT (
Payment_ID int(16) not null,
Amount_paid varchar2(30) not null,
Payment_ReceivedBy varchar(30) not null,
Payment_ReceivedFrom varchar(30) not null,
Payment_Date datetime not null, 
Card_Number varchar2(20) not null,
Card_Holder_Name varchar2(30) not null,
Is_CreditCard number(20) ,
Is_DebitCard  number(20),
Online_Payment varchar(10),
CashOnDelivery varchar(10),
CONSTRAINT PaymentID_PK PRIMARY KEY (Payment_ID)
);

错误：

ORA-00907: missing right parenthesis

Answer 1

错误消息不是很好，实际上问题并不在于括号 - 它与数据类型有关。 Oracle 没有 int 和 datetime 类型。相反，您可以使用number(16) 和date：

CREATE TABLE PAYMENT (
Payment_ID number(16) not null, -- Here
Amount_paid varchar2(30) not null,
Payment_ReceivedBy varchar(30) not null,
Payment_ReceivedFrom varchar(30) not null,
Payment_Date date not null,  -- And here
Card_Number varchar2(20) not null,
Card_Holder_Name varchar2(30) not null,
Is_CreditCard number(20) ,
Is_DebitCard  number(20),
Online_Payment varchar(10),
CashOnDelivery varchar(10),
CONSTRAINT PaymentID_PK PRIMARY KEY (Payment_ID)
);
