mysql在where条件下按列分组

Question

我怎样才能使这个查询工作:

SELECT column1.....,SUM(Hits) AS Hits   
FROM table 
WHERE  SUM(Hits) > 100
GROUP BY column1.....

问题是where子句，mysql显示错误:

Error Code : 1111
Invalid use of group function

我尝试将查询更改为:

 SELECT column1.....,SUM(Hits) AS Hits   
    FROM table 
    WHERE  Hits > 100
    GROUP BY column1.....

它没有帮助。

谢谢
