Question

我收到以下错误消息：

Msg 8120，Level 16，State 1，Line 1 专栏＆＃39; customers.member_category＆＃39;在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。 Msg 104，Level 16，State 1，Line 1 如果语句包含UNION，INTERSECT或EXCEPT运算符，则ORDER BY项必须出现在选择列表中。

如何通过案例订购结果？

由于

SELECT
Date,
order_id,
member_category,
COUNT(*) AS no_items, 
SUM(item_amount) AS total_amount
FROM 
order_items OI (NOLOCK) JOIN customers C (NOLOCK) 
ON OI.CUSTOMER_NO = C.CUSTOMER_NO
WHERE 
DATE = '01 FEB 2014'
GROUP BY 
order_id, 
member_category
UNION
SELECT
    '',
    '',
'Total',
COUNT(*) AS no_items, 
SUM(item_amount) AS total_amount
FROM 
order_items OI (NOLOCK) JOIN customers C (NOLOCK) 
ON OI.CUSTOMER_NO = C.CUSTOMER_NO
WHERE 
DATE = '01 FEB 2014'
GROUP BY Date WITH ROLLUP
ORDER BY Date ASC, CASE member_category WHEN 'VIP' THEN 1
                    WHEN 'STD' THEN 2                   
                    WHEN 'GLD' THEN 3 
           END

Answer 1

UNION语句的第二部分不包含字段member_category。这违反了UNION的基本原则，即每个语句中列的数量和顺序应该相同。

要解决此问题，您需要在检索到的列列表和member_category子句中添加GROUP BY。
