I've a database which contains tables:
-
Quest:
PK Name PK qName goal
-
Guild:
PK Name PK gName level
-
Game:
PK Name MaxPlayer levels uName
-
GuildQuest:
PK Name PK gName PK qName
I need to retrieve the game details that their level's value is higher than 1/10 the sum of guilds levels
This is what I've build so far:
SELECT
Name, MaxPlayer, levels, uName
SUM(level) AS guildsLevels
FROM
Guild
GROUP BY
level
I need to add the multiplication by 0.10 of the sum which I don't know how to do, and then check every game that its value is bigger than sum of guild levels multiplied by 10%.
I'm using MySQL (and PhpMyAdmin to run the queries).
