Mysql Hitung (*) sebagai Total WHERE Total?

Saya pikir Anda ingin memfilter grup. Gunakan HAVING COUNT(*) bukannya WHERE :

SELECT Id, QId, UName, Ans, Date, Count(*) * 10 as Total
FROM question
GROUP BY UName
HAVING Count(*)

Jika Anda ingin mengurutkan grup berdasarkan jumlah elemen, gunakan ORDER BY :

SELECT Id, QId, UName, Ans, Date, Count(*) * 10 as Total
FROM question
GROUP BY UName
ORDER BY Count(*) DESC
