我得到的错误是：＃1054 - “字段列表”中的未知列'价格'

Question

对于我的CIS类，我有SQL项目，我仍然是SQL的新手，并试图学习它。任何帮助将不胜感激。

查询：编写一个查询，以显示居住在圣何塞或特洛克的客户所有订单的总价值。

这是我试过的并给我一个错误：

select SUM(price * quantity) as Revenue
FROM customer,salesorder
where customer.cno = salesorder.cno AND
        zip = 95124 AND zip = 95380
        AND zip = 95382

我得到的错误是：＃1054 - 未知列＆＃39;价格＆＃39;在＆＃39;字段列表＆＃39;

Answer 1

你可以试试这个。

没有意义

AND zip = 95124 
AND zip = 95380
AND zip = 95382

我想你想使用IN

从表架构加入Orderline和Book，您将获得price和quantity

select SUM(b.price * o.quantity) 
FROM customer c 
INNER JOIN salesorder s ON c.cno = s.cno
INNER JOIN Orderline o ON s.ono = o.ono
INNER JOIN Book b ON b.bno = o.bno
where zip IN (95124,95380,95382);

Answer 2

检查列价格所在的表格后......我会在表格书中看到它然而你没有在查询中使用表格书......所以你应该这样做..

O(sqrt(n))

Answer 3

我得到的错误是：＃1054 - “字段列表”中的未知列'价格'

根据您的查询，您尚未添加具有价格列的表格。如果您可以在book表中看到您的DDL语句价格列，则必须加入此表才能获得所需的结果。我想这应该有用

SELECT  SUM(book.price*orderline.quantity) AS "order value" from customer 
JOIN salesorder
ON salesorder.cno=customer.cno 
JOIN orderline
ON salesorder.ono=orderline.ono
JOIN book
ON orderline.bno=book.bno 
JOIN zipcode
ON customer.zip = zipcode.zip
WHERE city in ('Turlock', 'San Jose')

Answer 4

需要纠正的第一件事是像sum，avg等聚合函数也需要一个group子句。例如

选择总和（价格*数量）作为客户c，salesorder的收入 c.customer_no = s.customer_no group by c.customer_no

它将返回单个客户生成的总收入。第二件事是对于基于多个邮政编码的过滤，您可以使用IN子句，如

其中zip_no位于（'A'，'B'，'C'）

请检查您是否正在编写正确的列名和列的拼写以及价格

来自表的SQL查询
