继续获取ORA-00904：“DISTRICT_ID”：无效标识符

Question

我不断收到该错误消息，并且经历了很多次，我无法弄清楚解决问题的最佳方法是尝试更改它一堆。

CREATE TABLE dealerships(

dealer_ID number(10)NOT NULL, 
location varchar2(20)NOT NULL, 
region_ID varchar2(20)NOT NULL, 
address number(10)NOT NULL, 
street varchar2(20)NOT NULL, 
city varchar2(20) NOT NULL, 
state varchar2(2) NOT NULL, 
zip number(10)NOT NULL, 
phone number(10), 
sq_ft number(10), 
date_opened varchar2 (30), 
manager varchar2 (30), 
distric_ID number(10), 
CONSTRAINT dealershipsID_pk PRIMARY KEY(dealer_ID)); 

INSERT INTO dealerships(dealer_ID, location, region_ID, address, street, city, state, zip, phone, sq_ft, date_opened, manager, district_ID) VALUES(001, '001', 'RG001', 001, 'STR001', 'Detroit', 'Michigan', 48307, 256897456, 55, '21March2016', 'Tom Petty', 001); 

INSERT INTO dealerships(dealer_ID, location, region_ID, address, street, city, state, zip, phone, sq_ft, date_opened, manager, district_ID) VALUES(002, '002', 'RG002', 002, 'STR002', 'Hollywood', 'California', 98290, 2565675309, 85, '1March2011', 'Randy Gilman', 002); 

Answer 1

认真吗？看看你的代码：

distric_ID number(10) 

和

district_ID) 

有错字。
