ORA-00904: "CUSTID": 无效标识符

问题描述

create table Customer(
    Custid number (20) primary key,Custname char(20),phno number(10),pan varchar2(20),dob date
    );

create table HomeLoan(
    HLoanid number (20) primary key,Amount number(10),foreign key(Custid) references Customer(Custid)
    );
    
create table VehicleLoan(
    VLoanid number (20) primary key,foreign key(Custid) references Customer(Custid)
    );
    

在执行上述创建表查询时，我收到一个错误

ORA-00904：“CUSTID”：无效标识符

解决方法

您忘记在 Custid 和 HomeLoan 表中创建列 VehicleLoan：

CREATE TABLE Customer (
    Custid number(20) PRIMARY KEY,Custname CHAR(20),phno number(10),pan varchar2(20),DOB DATE
    );

CREATE TABLE HomeLoan (
    HLoanid number(20) PRIMARY KEY,Amount number(10),Custid number(20),CONSTRAINT fk_customer FOREIGN KEY (Custid) REFERENCES Customer(Custid)
    );

CREATE TABLE VehicleLoan (
    VLoanid number(20) PRIMARY KEY,CONSTRAINT fk_customer FOREIGN KEY (Custid) REFERENCES Customer(Custid)
    );
