MySQLのGROUP BYクエリで複数の列を使用できないのはなぜですか？

Question

私は、3つの異なる列によってそのグループのSQLを作成する必要があり、これは私のクエリです：

SELECT 
    notification.type, 
    notification.triggerer, 
    notification.to_what, 
    ANY_VALUE(user_data.name) AS name, 
    ANY_VALUE(user_data.surname) AS surname, 
    ANY_VALUE(user_data.avatarimage) AS avatarimage, 
    COUNT(*) AS counter 
FROM notification 
INNER JOIN user_data 
    ON notification.triggerer = user_data.owner 
WHERE notification.owner = "c6cecc891f6c4cc84cc0b62062578e52" 
    AND isdelete=0 
ORDER BY notification.id DESC 
GROUP BY notification.triggerer, notification.type, notification.to_what 
LIMIT 0,100 

しかし、私はこれを作るとき、それは私にエラーを示しています

> #1064 - You have an error in your SQL syntax; check the manual that corresponds 
to your MySQL server version for the right syntax to use near 
'GROUP BY notification.triggerer, notification.type, notification.to_what 
LIMIT ' at line 15 

私はどのように修正することができますそれ？

あなたはそれを使用することができますが、あなたのごgroup byがorder by

SELECT 
    notification.type, 
    notification.triggerer, 
    notification.to_what, 
    ANY_VALUE(user_data.name) AS name, 
    ANY_VALUE(user_data.surname) AS surname, 
    ANY_VALUE(user_data.avatarimage) AS avatarimage, 
    COUNT(*) AS counter 
FROM notification 
INNER JOIN user_data 
    ON notification.triggerer = user_data.owner 
WHERE notification.owner = "c6cecc891f6c4cc84cc0b62062578e52" 
    AND isdelete=0 
GROUP BY notification.triggerer, notification.type, notification.to_what 
ORDER BY notification.id DESC 
LIMIT 0,100
