Mysql Count(*) som Total HVOR Total?

Jeg tror, ​​du ville filtrere grupper. Brug HAVING COUNT(*) i stedet for WHERE :

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

Hvis du skal sortere grupper efter antal elementer, så brug ORDER BY :

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