Mysql SQL-不正确使用Union和Order BY

我得到了错误“不正确使用UNION和ORDER BY”

我使用这个查询作为工具，我需要它来工作

我知道有一个解决方案，可以在两个查询的开头和结尾使用Parathesis（），但我的工具不能使用它

这就是为什么我需要一个其他的查询解决方案，而不是使用（）解决方案

还有其他解决办法吗

非常感谢您的帮助。。。从2天起就有这个问题了

干杯

试试这个：

SELECT Count(STATUS),
   STATUS,
   ROUND(Count(STATUS) * 100 /
           (SELECT Count(*)
            FROM call_view
            WHERE (create_month = Month(Now() - INTERVAL 1 MONTH))
              AND (create_year = Year(Now() - INTERVAL 1 MONTH))
              AND customer_company_name = "Company" ), 1) AS Percentage
FROM call_view
WHERE (create_month = Month(Now() - INTERVAL 1 MONTH))
AND (create_year = Year(Now() - INTERVAL 1 MONTH))
AND customer_company_name = "Company"
GROUP BY STATUS
ORDER BY COUNT(CALL_ID) DESC LIMIT 6
UNION
SELECT Sum(category_count),
   'Other',
   sum(percentage)
FROM
( SELECT Count(CATEGORY) AS category_count,
       COUNT(CALL_ID),
       CATEGORY,
       ROUND(Count(CATEGORY) * 100 /
               (SELECT Count(*)
                FROM call_view
                WHERE (create_month = Month(Now() - INTERVAL 1 MONTH))
                  AND (create_year = Year(Now() - INTERVAL 1 MONTH))
                  AND customer_company_name = "Company" ), 1) 
AS Percentage FROM call_view
WHERE (create_month = Month(Now() - INTERVAL 1 MONTH))
  AND (create_year = Year(Now() - INTERVAL 1 MONTH))
  AND customer_company_name = "Company"
GROUP BY CATEGORY
ORDER BY COUNT(CALL_ID) DESC LIMIT 6,
                                  1525125215) AS original_query

您是否试图根据完整的联合结果进行订购？（或者只是其中一个选择？）第一个查询检索调用最多的类别（位置1-6）。我希望它们按DESC排序。第二个查询检索别名“other”下的所有类别。所以我想按第一个查询排序，然后在结果末尾添加第二个查询非常感谢您的回复。我已经尝试过这个解决方案，它正在工作，但是parathesis（）在两个查询的开始和结束时都会给另一个工具带来问题。这就是为什么我需要一个不带（）的解决方案。括号在这里是必要的。是否有可能组合两个查询（如子查询）而不使用Union运算符？
