＃1111 - 无效使用组功能：MAX COUNT不适用于MYSQL5.5

Question

我有一个表userInteret，我想在用户之间选择最大的联系方式。 我试过这个问题：

SELECT nomInteretUser,idUser,COUNT(nomInteretUser) FROM `userInteret` 
WHERE nomInteretUser IN('piano','flute','chien') GROUP BY idUser

但是当我尝试这个时，我想要这个COUNT的MAX：

SELECT MAX(COUNT(nomInteretUser))FROM userInteret 
WHERE nomInteretUser IN('piano','flute','chien') GROUP BY idUser;

总是会出错：
