mysql在where where条件下按列使用group

Question

如何使此查询起作用:

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
