Mysql Count(*) som totalt VAR Totalt?

Jag tror att du ville filtrera grupper. Använd HAVING COUNT(*) istället för WHERE :

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

Om du vill sortera grupper efter antal element, använd ORDER BY :

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