Question

create table divorced_females 
select cust_id, cust_first_name,cust_last_name, cust_gender, cust_marital_status from customers 
where cust_gender = 'F' and cust_marital_status = 'divorced';

我收到如下错误：

从第1行开始的错误-
  创建表divorced_females
  从客户中选择cust_id，cust_first_name，cust_last_name，cust_gender和cust_marital_status
  其中cust_gender ='F'和cust_marital_status ='离婚'

错误报告
  ORA-00922：选项丢失或无效
  00922. 00000-“选项缺失或无效”
  *原因：
  *操作：

谢谢。

Answer 1

您在表名后缺少'AS'。

尝试以下声明：

create table divorced_females as
select cust_id, cust_first_name,cust_last_name, cust_gender, cust_marital_status 
from customers 
where cust_gender = 'F' and cust_marital_status = 'divorced';

Answer 2

CREATE TABLE AS语句复制所选列的语法为：

CREATE TABLE new_table
  AS (SELECT column_1, column2, ... column_n
  FROM old_table);

因此，在您的情况下查询将为

create table divorced_females  AS 
 (select cust_id, cust_first_name,cust_last_name, cust_gender, cust_marital_status 
 from customers 
where cust_gender = 'F' and cust_marital_status = 'divorced');

在此SQL查询中我做了什么错？
