MySql Sql MAX 和 SUM 错误

Question

select sum(value) as 'Value',max(value)
from table_name where sum(value)=max(sum(value)) group by id_name;

错误是:组函数的使用无效(ErrorNr.1111)

有什么想法吗？

谢谢。

你可以试试吗

SELECT Value, MXValue
FROM (
       select sum(value) as 'Value',max(value)  MXValue
       from table_name 
       group by id_name
     ) as t1
order by value desc
LIMIT 0,1

或者你可以尝试类似的东西

SELECT  id_name,
        Value
FROM    (
            select id_name,sum(value) as 'Value'
            from table_name
            group by id_name
        ) t
WHERE   Value = (
                    SELECT TOP 1 SUM(Value) Mx 
                    FROM table_name
                    GROUP BY id_name 
                    ORDER BY SUM(Value) DESC
                )

甚至使用内部连接

SELECT  id_name,
        Value
FROM    (
            select id_name,sum(value) as Value
            from table_name
            group by id_name
        ) t INNER JOIN
        (
            SELECT TOP 1 SUM(Value) Mx 
            FROM table_name
            GROUP BY id_name 
            ORDER BY SUM(Value) DESC
        ) m ON Value = Mx
